26 30 00 FACILITY ELECTRICAL POWER GENERATING AND STORING EQUIPMENT

.01 Essential (Emergency and Standby) Power Systems

1. Emergency power source at the University Park Campus should typically be the campus “emergency” and, when required, the campus “standby” cable systems (4160Y/2400V).  Coordinate availability with Engineering Services.
2. Where the emergency cable system is not available an engine driven generator shall be provided.  Emergency system distribution voltage should be 480Y/277V or 208Y/120V for three phase installations (greater than 50 KVA) and 240/120V for single phase installations (less than 50 KVA).  For further requirements, refer to 26 32 13 Engine Generators. 
3. Wiring from each branch of the essential power systems shall be kept separate from each other and the normal power system.

.02 Life Safety Power

1. The Life Safety (NEC 700, code required emergency systems) power source at the University Park Campus shall be the campus “emergency” cable system (4160Y/2400V) wherever possible.  Coordinate availability with Engineering Services.
2. When provided by the University “emergency” cable, installation shall include:
1. Primary fused disconnect switch with current limiting fuses and lighting arrester
2. Dry type, high-efficiency transformer
3. Secondary overcurrent protection
4. Transfer switch
5. Provide provisions for power meter (meter provided by PSU).  Provisions shall match those as noted in Electricity Metering section.
3. Life Safety service Loads shall include, but not be limited to:
1. Egress lighting
2. Exit signage
3. Fire alarm system
4. Sprinkler equipment
5. Smoke detection system
6. Telephone equipment
7. Building Automation System infrastructure equipment

.03 Critical Power

1. Installation only to occur when approved by Engineering Services.  The Critical Branch (NEC 701, legally required standby systems) power source at the University Park Campus shall utilize the campus “standby” cable system (4160Y/2400V), wherever possible.  Coordinate availability with Engineering Services.
2. When provided from the “standby” cable, installation shall include same components as the Life Safety Power system. 
3. Critical service Loads shall include, but not be limited to:
1. Elevator, but only when required by AHJ
2. Animal rooms
3. Other loads as required by AHJ

.04 Standby Power

1. The Standby Branch (NEC 702, non-required standby systems) power source at the University Park Campus shall utilize the campus “standby” cable system (4160Y/2400V) wherever possible.  Coordinate availability with Engineering Services. 
2. When provided from the “standby” cable, installation shall include same components as the Life Safety Power system.
3. Standby service loads shall include, but not be limited to:
1. Class 1 (irreplaceable) research loads shall be determined by each College.  Utilize dedicated breaker and single twist-lock receptacle per “Devices” section.  Coordinate these loads with the Engineering Services so that they can be numbered and tracked.
