from the editorDo we really have a labour squeeze?Recognize that youwill need to train.One of the things that makes my job interesting isI never know what may cross my desk. The otherday, I received a statement from the CEO ofActionCoach Canada, Greg Kopchuk, who has surveyedover 1000 business owners across the country. He askedthem what was most challenging about running theirbusinesses, and always among the top answers was:Finding good people.Which led Kopchuk to wonder whether there wasreally an employment problem, or whether businessessimply couldn’t find people who were willing to workhard and be trained.“Canadian employers need to take the time to trainpeople in their industry,” concludes Kopchuk, addingthey also have to take a more active role in the recruitmentprocess.He’s definitely right about taking a bigger interest inthe recruitment process, though he’s not the first to bringthis to light. Back in January 2008, for example, I wroteabout a session on “Recruitment Interviewing” deliveredby Cheryl Crumb at NETCO’s (National <strong>Electrical</strong>Trade Council’s) 2007 National Training Symposium.She explained the nuances of interviewing, particularlyas it relates to a potential apprentice candidate, orapprentice for your company (though these techniquescan apply to anyone, anywhere). Like onions, peoplehave many layers, and she identified the three layerswith which interviewers should be concerned.Let’s cut to the chase: it’s Level 3 we want.A person’s third layer (Level 3) reveals their attitudesand job beliefs; this ultimately tells you the kind ofperson you’re bringing on board, and whether you’ll behappy with them.“We must learn to ask Level 3 questions from theoutset,” Crumb said, arguing we shouldn’t place toomuch importance on resumes, which only serve to listthe basic things the candidate must have. “Beyond that,[resumes] tell you nothing of the individual [and] let’sface it: an electrical apprentice won’t consider resumewritingan Essential Skill.”Several years later, Kopchuk is providing the sameadvice for finding the best employees. “Look for attitudefirst. If you find talented/hardworking people, hire themright away,” he says, adding those people are out there—you just need to put some effort into recruiting them.Recognize that you will need to train. Everyone hastheir own way of doing things, and schools—howeverwell-meaning—simply cannot keep pace with businessand technology. Use this to your advantage whenrecruiting. “Offer to give [candidates] the skills theyneed,” says Kopchuk. “That way, you’ll get the employeeyou want and skills that will benefit your business.”And, again, Kopchuk emphasizes attitude over skills,and I couldn’t agree with him more: “Don’t hire skillsover attitude. One person with hustle is worth 10 peoplewho don’t care”.ContentsFEATURESDEPARTMENTSStock photoOn the coverand page 14Smart gridoutlook 2010:<strong>Business</strong> benefit, data,analytics and customercentrictechnologies aheadSeveral trends will continueto drive smart grid activity in2010, based on the notion thatthe smart grid is really justan integrated toolset toefficiently plan, design andreliably operate the grid in asustainable manner.18 The role of overcurrent protectivedevices in electrical safetyProperly spec’d and installed overcurrent protective devices can go a long way in helping minimizethe catastrophic effects of an accidental arc flash/blast.22 Continuing education & training keyto information technology successForward-thinking electrical contractors are addingdatacom to their list of one-stop services; but to keeppace with technological change, they face the sameeducational challenges as students just entering careers incommunications infrastructure.24 They say “class-leading” and“segment-best”, but you decideEBMag was pleased to have the opportunity to sit in on amedia-only, sneak peek of Chevrolet’s new 2011 Silverado HDbefore it was officially shown off at the Chicago Auto Show...and Chevy execs are pretty pleased with whatthey’ve assembled.4 Industry News7 Calendar10 Mind Your SafetyHard hats and jerking knees... again12 From the Legal DeskDuty of fairness restored in tender situations16 Letters to the Editor26 Products30 Code FileInterconnecting solar power systems30 The Code Conundrumpage 26www.EBMag.com • April 2010 • 3

mind your safetyBy Dave SmithHard hats and jerkingknees... againMy column regarding foam-insert hard hatsseems to have created a bit of controversy(EBMag Dec/January 2009/10, “Heads upand hats off with foam inserts”). I received anemail from an individual who was concerned mycolumn may be misconstrued. He writes:I am very worried that your article will [push]the electrical community to [a] knee-jerkreaction, and many workers—as you say—[may] exercise the right to refuse unsafe work.In that column, I advise that when you arewearing a foam-insert hard hat inside theLimited Approach Boundary or Flash ProtectionBoundary, you should ensure that it has been arcflash or flame-resistant tested. Since there ispresently no standard for testing these materials,this cannot be done.A sidebar to the article referenced a video clipof a foam-insert igniting and melting the plastichard hat. The result was a hard hat that drippedto the floor around the test mannequin.Critics of the video have focused on the factthat it showed a 15-calorie test, claiming it isinvalid because, with 15-cal exposure, you wouldbe required to wear Category 3 FR clothing.(Which, by the way, is absolutely correct if youknew you were being exposed to 15 calories ofincident energy. If you identify the incidentenergy as 15 cal, then you definitely need to bein a Category 3 suit with a minimum rating of25 cal, plus other PPE listed in Table 5, page 48of CSA Z462, “Workplace <strong>Electrical</strong> Safety”.)But if you thought you were being exposed toa Category 0 HRC (based on the tasks in Table4, page 43, or incident energy below 1.2 cal, asstated on an equipment label), then the presentindustrial standard is to only wear a hard hat andsafety glasses. If that hard hat was of the foaminsert variety, you would have a risk.The first step prior to doing any electricalwork is to perform a Hazard/Risk Evaluation (pg22, 4.1.7.6 and pg 99, Annex F). You need tounderstand that, when the incident energy at 18in. from the source of the energy is determinedIdeal_EB_April10.indd 110 • April 2010 • www.EBMag.com3/17/10 1:30:37 PM


mind your safetyI do not espouse knee-jerk reactions,but I’m all for some kind of reaction...to be 1.2 cal then, as you move closer tothe source, the incident energy would—theoretically—increase by the inverse ofthe distance squared (1 ÷ distance ratio 2 ).So at 9 in., the distance decreases by half(9 in. versus 18 in.), and the incidentenergy shoots up to 4.8 cal. At 5 in., theincident energy rockets up to 15.6 cal!These distances are easily achieved whenyou lean forward to take a close look atsomething while troubleshooting anenergized circuit. When that happens,trust me—your exposure is no longer amere 1.2 cal.In addition, when you are workingdownstream from an older circuit breakerthat’s out of spec, you would have no idea:a) how fast that circuit breaker wouldactually operate, or b) whether it actuallycan operate.Several years ago, members of NETA(InterNational <strong>Electrical</strong> TestingAssociation) conducted a study in whichthey performed tests on 34,000 circuitbreakers; of those, 10.5% did not operateat all, and a further 23% did not openwithin their specifications.This means that 33.5% of 34,000breakers would constitute a serious hazardto any worker working downstream who isalso relying on an arc flash hazard studythat says 1.2 cal or task tables indicatingCategory 0.So why is this 15-cal video clip valid?Because 1.2 cal at 18 in. and 2 cycles ofclearing time becomes 19.2 cal by leaningin within 9 in. of equipment protected bya device that takes 8 cycles to open.There is chaos and uncertainty withinall of the arc flash work we do. Ourequipment is getting older and older. Youknow the age of the equipment you faceevery day, and you know the last time itwas properly maintained. Even when yougo into a facility whose maintenancehistory is a mystery, it does not take youvery long to get an understanding of whatit looks like, smells like, feels like andsounds like.In truth, I am astounded that anyonewould be react negatively to that column; itis a slam dunk that you do not wear meltingmaterials on your body when you may beexposed to energized electrical systems. Ido not espouse knee-jerk reactions, but I’mall for some kind of reaction... preferably onethat leads to action.Let’s face it... every safety interventionhas had its opponents and detractors:steel-toed boots are too heavy; hard hatsmake you bang your head; safety eyewearis a scratchy waste of time; gloves are bulky; FRclothing is hot; if we do this, our productivity willsuffer... ad infinitum, ad nauseam!Kurt Lewin’s Force Field Analysis shows that, forevery good intention, there will be a force thatopposes it, and the former must possess greaterforce to override the negativity of the latter. It hastaken many deaths, disfigurements and amputationsto get electrical safety to where it is today.But there’s more to do.Arc flash danger is based on time, current anddistance, and to turn a 1.2-cal danger into a 15-calflash, it takes two things: move in closer, and havea poorly operating protective device. Regardless, ifit can melt (like the foam insert), keep it awayfrom your electrical systems.Until next time, be ready, be careful and besafe.©Canada Training Group has been providing consultingservices to industry since 1980; Dave Smith, thepresident, can be reached at davesmith@canadatraining-group.ca.At www.canada-training-group.ca,you will find this article (and others) available to you.Feel free to use them to support your own safetyprogram and other initiatives.A pioneer in the design of teck cablefittings, the Thomas & BettsSTAR TECK ® product line remainsan indisputable industry standard tothis day.All STAR TECK ® fittings are designedand manufactured in Canada forCanada.STAR TECK ® cable fittings.A tradition of industry firsts.CTG_EB_March10.indd 12/16/10 10:01:21 T&B_vert_EB_April10.indd AM1www.EBMag.com • April 2010 • 113/9/10 2:02:58 PM


from the legal deskBy Stephen Tatrallyay, LLBDuty of fairness restored in tender situationsAfter nearly a year’s wait, the Supreme Courtof Canada released its decision in TerconContractors v British Columbia Ministry ofTransportation, 1 in which it essentially declared: a)that the duty of fairness applies in RFPs as well astender situations; b) an exclusionary clause must bereviewed on its own merits to determine whether itcan function to set aside the usual duty of fairness;and c) the Contract A/B form of analysis subsists. Thatanalysis requires the owner or others submitting arequest for tender to treat all those submitting tendersfairly; specifically, they cannot apply undisclosed rulesor criteria when judging those bids ([2010] SCC 4).The majority of the court also ruled that thisAs the recognized leader in the lighting industry,our mission is to deliver consistently superior valueto our customers.

All rights reserved.decision should settle the issue“once and for all”.Background to Tercon caseThis case involved a road constructionproject for which BC’s Ministryof Transportation issued calls fortender. Of the six bids received, notone came even close to budget, sothe ministry withdrew the project,redesigned it, and reissued it as anRFP, advising all concerned thatonly bids from the six original tendererswould be considered.The RFP contained an exclusionaryclause to the effect that the meresubmission of a bid constituted arelease of any claim against theCrown as a result of participating inthe tender.One of the original bidders enteredinto a joint venture with a companythat specialized in certain aspects ofthe work, enabling him to reduce hisprice. He, not Tercon, was subsequentlyawarded the work.Tercon conclusionThe court held that, in interpretingsuch a clause, it should first bereviewed to determine whether itactually applied to the persons andsituations under review by looking atboth the facts of the situation andthe rest of the contract under review.The evidence was that the BCCrown knew perfectly well of thefacts surrounding the joint ventureand proceeded to award the contractanyway. Indeed, there wasevidence they ‘covered up’ the facts.The concepts that only compliantbids will be considered, and theimplied obligation to treat all biddersfairly, are factors thatcontribute greatly to integrity andbusiness efficacy. By submittingtheir joint venture bid, the bidder—who wasn’t Tercon—had submittedan unqualified bid which was incapableof acceptance.It is to be hoped that this definitivepronunciation will finallysettle the question, and eliminatedebate on the adequacy or acceptabilityof any tender.Stephen Tatrallyay is certified by theLaw Society as a specialist in ConstructionLaw, and has been presidentof the Canadian College of ConstructionLawyers (CCCL) and both theNational and Ontario branches of theConstruction Law Section of the BarAssociation.

However, based onour work at Telvent with hundreds ofutilities in North America and around theworld, we have found several trends thatshould continue to drive activity in 2010.We base these observations on our ownstraightforward definition of smart grid,which is:An integrated toolset to efficiently plan,design and reliably operate the grid ina sustainable manner.While there are many factors that affect griddevelopment—such as a diverse customerbase, cost of power, operational hurdles ofincreasing demand to a stressed deliverynetwork, and peak demandmanagement—we believe one of the mostsignificant factors driving smart grid trendsin 2010 will be the shift in governmentregulations. Government regulation isevolving away from creating generalmandates and moving toward judging thebusiness and social benefits of additionalsmart grid investments suggested by utilities.It is likely those investments will fit thetrends described below.More customer-centric technologyUtilities will continue to invest in customercentrictechnologies, including smart meters,home-based smart devices, demand-responsedevices and associated networks. Some ofthese are mandated by governmentregulation (as in Canada) while otherutilities are aggressively pursuing theseinvestments to enhance customercommunication, to better understandconsumption patterns, and to enabledemand response. Dozens of requests forproposal, contract announcements andimplementation projects have been initiatedover the past two years, and that trend islikely to continue for at least two more, asmany of the projects will be completedwithin that period.Better analytics to reduceoperations costsUtilities are beginning to understand thatanalytical engines such as DistributionManagement Systems (DMS) will bringdetailed knowledge about distributionnetworks that has not existed in the past.Dispatchers will be able to manage thenetwork to avoid overloads, balance loads,manage voltage and determine the mosteffective use of demand response (at peakand at other times).In addition, DMS enables stronger outagemanagement capability and identifiespotential loss points for investigation. Up tonow, there has been a rush to collect datafrom the field, which has led to a massivesurge in the demand for smart meters andother devices. Utilities now understand that14 • April 2010 • www.EBMag.com


a better approach is to installmeasurement devices inconjunction with analytic software;they not only measure but provideintelligence regarding theoperation of the network in realtimeand into the future.The recent use of DMSsoftware at Progress Energy andthe University of Michigan in theUnited States (and at severalutilities worldwide) demonstratesthis trend.Data managementand securityThe smart grid brings with it agreat deal of additional data tomanage, plus many additionalattributes and data types. Newassets like smart meters and smartswitches will be added, andinformation must be maintainedabout those devices. Data will becollected from those assets morefrequently than they are today, andwill raise challenges for managingthe data for many uses.Utilities will start to deal moreaggressively with the reduction ofthe number of databases to ensurethe integrity of the data that ismaintained, including automatingwork processes that update assetinformation. Also, governmentregulation and common businesspractice will force a dramatic risein the attention given to security ofboth the data and of the devicesthat collect it.Utilities will focus smart gridefforts on business benefitUntil now, the priorities for thesmart grid were often set by governmentregulators. Once these initialinvestments are completed, however,utilities will continue with incrementalinvestments that providestrong business benefit. For someutilities, the investment will result incost savings, such as the cancellationof power plant construction or ofcircuit reconstruction to handleincreasing demand (for example, theinflux of electric vehicles and theircharging stations).For other utilities, increased reliability,reducing outages andinterruptions, and managing voltagecarefully to improve quality of servicewill be the objective. And, forothers, success will be defined bystronger customer interaction, whichwill provide both new revenue andconservation opportunities, andchange the demand patterns toenable growth of consumption withoutsignificant investment.In all instances, these changeswill provide the ultimate benefit of addedsustainability to our already fragileenvironment.New technology to monitordistribution networkUtilities will add technologies to moreclosely monitor the distribution network toenhance its management and integrity.Coupled with DMS analytical functionality,SCADA systems will grow through additionalRemote Terminal Unit (RTU)deployments to provide a more comprehensiveview of the power deliverynetwork.Because voltage management willrequire RTUs to employ more precisesensors, the industry is responding withthe development of smart RTUs; theaddition of motorized switches inconjunction with those RTU deploymentswill enable the level of ‘self-healing’ thatimproves the integrity of the powerdelivery network.Of course, utilities will have to deal withthe challenges that these smart gridadvancements will bring. For example,traditional ‘silo’ functions in utilities willneed to integrate more effectively.Customer service, system operations,engineering, maintenance and otherfunctions will be collaborating on smartgrid issues in a manner that is differentthan traditional work practices of the past,and may, as a result, be one of the moredifficult goals to achieve.Utilities will simply have to organizethemselves around important businessprocesses (new service design andInterop_EB_April10.indd 1<strong>Business</strong> benefit,data, analytics andcustomer-centrictechnologies aheaddeployment, outage management) whileretaining traditional organizations tocultivate and grow important skill sets.Intense growth aheadThe smart grid era is driving significantchanges to utilities and their customers,and these trends provide a level ofunderstanding of where we are today andwhat to expect in 2010—and beyond. Thenext few years should be, as a result, aperiod of intense growth and change in anotherwise unchanging industry.Andy Zetlan has more than 35 years of utilityindustry experience and an advancedknowledge of smart grid technology.

lettersPlug-n-play not meantto replace electriciansI was very interested in your editorialregarding plug-n-play inthe electrical installation industry(EBMag February 2010, “Is electricityever plug-n-play?”). The term‘plug-n-play’ is also being banteredabout in the heavy industrial installationindustry.Technically, it pertains to thesame type of technology—namely,end devices with ‘plug-in’ receptaclesand connecting cables withpre-terminated connectors. Theintention is to reduce expensiveinstallation/termination hours inthe field with far less costly hoursin a shop where the receptacles andconnectors would be installed.Make theSwitchThe savings from the use of theplug-n-play in the field instead ofthe typical cable glands and terminalstrips would more than pay for theinstallation of the receptacles and connectorsin a controlled shopenvironment. This new plug-n-playtechnology is not meant to removeelectrical work from trained electricians,but to move the work to moreeconomical locations.I agree that this move to moreefficient termination procedures (suchas that being touted in the solarindustry) should not be seen as anopportunity to move work away fromproperly trained electricians who areresponsible for the proper installationof the equipment.While policing the Average Joehomeowner electrician is an ongoingissue with the local inspectiondepartments, it should not hinder theongoing effort to make electricalinstallations as efficient as possible.George Morlidge, Chief <strong>Electrical</strong> EngineerSubject Matter Expert, Codes andInstallations, Fluor Canada Ltd.BeforeAfterElectricity demandselectrical workersJust read your Editor’s article re.

Figure 4aFigure 4bTEST 1: Staged test protected by LPS-RK-30SP, Low-Peak current-limiting fuses (Class RK1). These fuses were in current-limiting range and cleared in approximately 1⁄4 cycle (0.004 s).Analysis results in incident energy of less than 0.25 cal/cm 2 and arc flash protection boundary of less than 6 in. per IEEE 1584 (simplified fuse equations).Figure 5Salisbury_EB_April10.indd 120 • April 2010 • www.EBMag.comArc-flash testsThe photos and recorded sensor readings fromactual arcing fault tests illustrate this pointvery well. An ad hoc electrical safety workinggroup (within the IEEE Petroleum andChemical Industry Committee) conductedtests to investigate arc fault hazards. (Thesetests and others are detailed in “Staged TestsIncrease Awareness of Arc-Fault Hazards in<strong>Electrical</strong> Equipment”, IEEE Petroleum andChemical Industry Conference Record,September, 1997, pp. 313-322.) One finding ofthis IEEE paper is that current-limitingOCPDs reduce damage and arc fault energy(provided the fault current is within thecurrent-limiting range).To better assess the benefit of limiting thecurrent of an arcing fault, it is important tonote some key thresholds of injury for humans.Results of these tests were recorded by sensors3/17/10 11:39:49 AMon mannequins and can becompared to these parameters:• Just-curable burn threshold:80°C (0.1 s)• Incurable burn threshold:96°C (0.1 s)• Eardrum rupture threshold:720 lb/sf• Lung damage threshold:1728 to 2160 lb/sf• OSHA required ear protectionthreshold: 85 db (for sustainedperiod). Note: an increase of3 db is equivalent to doublingthe sound level.All three tests were conducted onthe same electrical circuit set-upwith an available bolted threephase,short-circuit current of22,600 symmetrical RMS amps at480V. In each case, an arcing faultwas initiated in a size 1combination motor controllerenclosure with the door open, asthough an electrician wereworking on the unit ‘live’ or beforeit was placed in an electrically safework condition.Tests 4 and 3 were identicalexcept for the overcurrentprotective device protecting thecircuit. In Test 4, a 640-amp circuitbreaker with a short time delay isprotecting the circuit; the circuitwas cleared in 6 cycles. In Test 3,KRP-C-601SP, 601-amp, currentlimitingfuses (Class L) areprotecting the circuit; they openedthe fault current in less than 1⁄2cycle and limited the current. Thearcing fault was initiated on theline side of the motor branchcircuit device in both Tests 4 and3. This means the fault is on thefeeder circuit but within thecontroller enclosure.In Test 1, the arcing fault isinitiated on the load side of thebranch circuit OCPDs, which areLPS-RK 30SP, 30-amp, currentlimitingfuses (Class RK1). These


fuses limited this fault current to amuch lower value and cleared thiscircuit in about 1⁄4 cycle or less.The following results wererecorded from the various sensorson the mannequin closest to thearcing fault. T1 and T2 recordedthe temperature on the bare handand neck, respectively. The handwith T1 sensor was very close tothe arcing fault. T3 recorded thetemperature on the chest underthe cotton shirt. P1 recorded thepressure on the chest. And thesound level was measured at theear. Some results “pegged themeter”, meaning the specificmeasurements were unable to berecorded in some cases becausethe actual level exceeded therange of the sensor/recordersetting. These values are shown as(>), which indicates the actualvalue exceeded the value given,but it’s unknown how high of alevel the actual value attained.Conclusions drawnfrom testingA couple of conclusions can bedrawn from this testing.First, arcing faults can releasetremendous amounts of energy inmany forms in a very short period.Look at all the measured valuescompared to key thresholds ofinjury for humans given in theparagraph above. Test 4 wasprotected by a 640-amp, noncurrent-limiting device thatopened in 6 cycles or 0.1 s.Second, the overcurrentprotective device’s characteristicscan have a significant impact onthe outcome. A 601-amp, currentlimitingOCPD protects the circuitin Test 3. The current that flowedwas reduced (limited) and theclearing time was 1⁄2 cycle or less.This was a significant reductioncompared to Test 4.Compare the Test 3 measuredvalues to the key thresholds ofinjury for humans, then the Test 4results. The measured results ofTest 1 are significantly less thanthose in Test 4, and even those inTest 3. The reason is that Test 1employed a much smaller(30-amp), current-limiting device.Tests 3 and 1 both show there arebenefits to using current-limitingOCPDs. Test 1 just proves thepoint that the greater the currentlimitation,the more the arcingfault energy may be reduced.Both Test 3 and Test 1 employedcurrent-limiting fuses, but thelower amp-rated fuses limit thecurrent more than the larger ampratedfuses. It is important to notethe fault current must be in the currentlimitingrange of the overcurrent protectivedevice to receive the benefit of the lowercurrent let-through.

To theinformation transport systems (ITS)industry, your understanding of thetransmission of infrared bandwidthlight pulses or electrical signals needsto keep up with changes impactingtransmission. The productivity, profitabilityand credibility of today’s ITScompany is impacted by its employees’ability to make informed decisionsabout installing IP-addressable deviceson good quality, properly designed ITinfrastructure.Productivity and liability are integralcomponents of ITS and many otherindustries. Knowing how to simplymake connections quickly with compatibleproducts is as important as itever was; however, knowing ‘best practices’defined by subject matter experts(SMEs) is a very productive way ofbecoming the best in the industry.Install times are still important, butonly when there are no repair calls ordata throughput issues.Whether you have been in theindustry for decades or you are juststarting to consider a new career in ITat the infrastructure level, it is importantthat you are aware of, and staycurrent in, new and changing lifesafety codes, performance-focusedstandards and best practice information—allof which combine withindustry expertise to maximize productivityand minimize liability.BICSI is a globally focused associationthat works to improve anindividual’s knowledge specific to ITinfrastructure. <strong>Electrical</strong> contractorsand electricians can benefit from theefforts of BICSI staff and the hundredsof BICSI volunteers who makeup its board of directors and committees.The efforts of these individualsnot only provide direction to theindustry as a whole, but produce contentfor technical publications thatprofessionals worldwide use to keeppace with technological advancements.RCLighting_EB_April10.indd 122 • April 2010 • www.EBMag.com3/23/10 8:48:06 AM

This 360 W lamp, which operates on atraditional 400 W ballast, has 29 % higher maintained lumensthan that of a traditional 400 W universal metal halidelamp, in turn, resulting in a longer usable lamp life. As aresult, this increase in lamp life extends the relampcycle thus, substantially reducing maintenancecosts. Ignitek is a direct replacementfor existing metal halide lamps. Due to thepatented and time tested FEC ignitor insidethe lamp, which generates a starting pulsenecessary to ignite its high performance arctube, no installation of a special ballast orignitor is needed.www.standardpro.comRAYLEWPOWER SYSTEMS INC.Electric Power Generating Equipment Inc.www.raylewpower.comWANTEDMolded Case Circuit Breakers.

code fileKris Paszkowiak, P.Eng.Interconnecting solar power systemsEver-increasing electricity bills are causingsome concerned homeowners to considerthe installation of solar panels on theroofs of their homes. Whether motivated bythe impact on their pocketbook or the desireto be greener and, thus, reduce their carbonfootprint, these homeowners are embracingnew ideas for alternative energy generation.Whatever their motivation, their goal wouldultimately benefit all ratepayers by reducingdemand on the provincial power grid.In Ontario, for example, the Ontario PowerAuthority has introduced a Feed-in Tariff(FIT) program for renewable energy projects.One component of that program is somethingcalled ‘microFIT’, which applies to small,renewable power-generating projects of10kW or less. Prices under the microFITprogram range from $0.11/kWh for landfillgas projects to very substantial $0.80/kWh forsolar photovoltaic systems.(More information, including the limits onthe domestic content requirements for PV systems,is available at www.powerauthority.on.ca.)Questions and answers compiled by the <strong>Electrical</strong> Safety Authority VISIT WWW.ESASAFE.COMTackle The CodeConundrum...if you dareAnswers to this month’squestions in May’s<strong>Electrical</strong> <strong>Business</strong>.How did you dowith March’s quiz?Are you a...Master Electrician ?

For example,Section 50 contains specific rules pertaining tothe installation of solar photovoltaic systems,while Section 84 deals with interconnecting theelectric power production sources with thesupply authority system.Also, we need to remember all of the otherapplicable sections, such as Sections 4, 10, 12,14 and 26.The ability to disconnect the photovoltaicsystem is critical; the visible single point ofisolation provides safety for the supplyauthority’s staff, as well as any person whomight be performing any repairs orcomponent replacements. Rule 50-012“Disconnecting means”, requires that adisconnect switch be provided to disconnectall equipment—including the powerconditioningunit—from all ungroundedconductors of all sources. When theAnswers to Code Conundrum<strong>Electrical</strong> <strong>Business</strong> March 2010Q-1: Armoured cable is permitted to befished into a wall cavity containing nonmetallicsheathed cable.b) False. Rule 12-612.Q-2: Where receptacles exposed to theweather are installed in surface-mountedoutlet boxes, the cover plates shall beheld in place by two screws or by someother equivalent means.b) False. Rule 26-702(2) requires thecover plate be held in place by fourscrews, or some other equivalent means.Q-3: The branch circuit supplying acathodic protection system rectifier shallbe permitted to supply additional outlets.b) False. Subrule 80-008 states thebranch circuit shall be provided solely forthe cathodic protection system rectifier.equipment in question is energized from morethan one source, the disconnecting means shallcomply with Rules 14-414 and 14-700.The second critical requirement is the use ofa grid-dependent inverter certified to CSAC22.2 No. 107.1-01 “General Use PowerSupplies”. Where inverters approved for gridinterconnection are used, the anti-islandingfeature will automatically isolate the solarpanels from the supply authority upon loss ofsupply authority voltage. However, varioussupply authorities and inspection authoritiesinsist on enforcing Rules 84-022“Disconnecting means – Supply authoritysystem” and 84-024 “Disconnecting means –General” because they do not want to rely onthe electronics, and because of the concern thateven a small generator can magnetize thedistribution transformer primary, resulting in ahazard to linemen.The installation of even a small solarpoweredsystem can get complicated, andthere’s major cost involved. A typical 3kW to4kW solar panel system can have a price tag ofabout $40,000 to $65,000. Other concerns aretechnical in nature and some are not, such asassessing the solar panels’ exposure to the sun,available roof area and roof integrity, buildingcode requirements, insurance and taximplications, etc.Kris Paszkowiak is principal of CodeSafetyAssociates, a consulting firm serving the needs ofthe electrical industry.
