DIVISON 26: ELECTRICAL<br />
A. Electrical Gear<br />
1. Preferred Br<strong>and</strong>s<br />
a) Square D*<br />
b) Eaton<br />
c) GE<br />
d) Siemens<br />
2. Specify Arc Flash Hazard, Coordination Study <strong>and</strong> Labeling for all new<br />
electrical panel boards <strong>and</strong> switchboards<br />
B. Upgrade existing utility services (electric, water, gas (excluding kitchen); do not add<br />
meters; single site service preferred, if economically feasible; consider future expansion<br />
(Plan for Ease-of-Expansion with alternative layout locations for future added classroom<br />
additions. Preference is for existing metering to be monitored for real-time retrieval <strong>and</strong><br />
archiving of kW peak dem<strong>and</strong> <strong>and</strong> kWH use; same for new metering should it be<br />
required if economically not feasible to do so without.)<br />
1. Data Pulse-type Meter (Duke Energy Spec)<br />
C. Transient Voltage Surge Suppression (TVSS)<br />
1. Preferred br<strong>and</strong>s<br />
a) DITEK<br />
b) Liebert<br />
c) LEA International<br />
d) Current Tech<br />
e) Square D<br />
f) Eaton<br />
g) GE<br />
h) Siemens<br />
2. Surge suppression devices shall be designed into electrical <strong>and</strong> low voltage<br />
devices<br />
3. Specify or provide surge suppression on all panel boards feeding roof mounted<br />
or exterior equipment<br />
D. Lighting Fixtures<br />
1. Lamp specifications:<br />
a) No U shape lamps; St<strong>and</strong>ard Bulbs Only. T8 bulbs<br />
b) Minimum Color Rendering Index (CRI) of 80<br />
c) Color Temperature (CCT) 4100 Deg. Kelvin<br />
d) Mean lamp lumens (at 40% of rated life) at least 94% of initial lumens<br />
e) 36,000 hour @ 3hrs/start to 42,000 hour @ 12 hrs/start<br />
f) Low Mercury content<br />
