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 />

2. Fixture specifications:<br />

a) 2’X4’ fixtures, recessed parabolic, 3” deep min., 70% min. efficiency<br />

b) Direct/Indirect Pendant baffled, 80% min. efficiency<br />

c) Surface mounted Baffled, Wide Distribution, 64% min. efficiency<br />

3. Ballast specifications:<br />

a) High-frequency electronic ballasts using instant start or program rapid<br />

start circuitry<br />
