Due to the magnitude of the load for the HCL it will be necessary to obtain serv ce from one of the 4kV i
buses in the turbine building.
In addition, a second source of 480 volt power will be used to provide redundant service to selected essential building loads.

6.14.2.2 A unit substation, 4160 to 480 volt, single ended, 3 phase, will be provided to supply 480 volt power and lighting loads.
This unit substation will normally power the majority of the facility loads.
Those loads requiring a backup source of power (the drainage transfer pumps, building exhaust fans, perchloric acid hood fans, glove box booster fan, normal lighting, and bench and hood power receptacles) shall normally be connected to a separate 480 volt source.
Provision will be made within the facility to manually transfer these loads to the HCL unit substation, which will be rated to carry all facility loads simultaneously.
6.14.2.3 A motor control center will be energized directly from a 480 volt substation.
The 480/277 volt lighting and distribution panels shall be energized via 480 to 480/277 volt transformers from this sub-station and the motor control center.
The 120/240 volt lighting and distribution panels shall be fed from the motor control center or distri-bution panelboards via stepdown transformers.
Branch circuits shall be supplied through individual circuit breakers within the panel boards.
6~.14.2.4 Voltage sensitive loads requiring a regulated and isolated power source will be supplied from voltage regulating /isclating trans-formers.
In addition, these loads will be connected such that, upcn loss of voltage, a manual reset will be required to re energize the equipment following a restcration of power.
6.14.2.5 125-volt de power from the existing plant de panels will be provided for substation breaker control power.
