Miscellaneous
Standard accessories and components in accordance with IEEE C57.15 shall be
provided. The regulator subbase shall elevate the lowest live part of the
regulator to a height of at least 2.7 m 9 feet above the concrete pad on

Station Battery
**************************************************************************
NOTE: Normally, an 8-hour requirement will be
sufficient. Indicate required annunciator system
connections on the project drawings. Coordinate
battery types and characteristics with the
manufacturer.
**************************************************************************
The station battery installation shall include a battery, battery racks, a
battery charger, and protective equipment. The station battery
installation shall be housed [in the metal-clad switchgear] [where
indicated].
2.9.2.1
Battery
The battery shall consist of the required number of [lead-calcium]
[nickel-cadmium] cells interconnected with proper connectors provided by
the battery manufacturer to provide a nominal battery rating of [48] [125]
volts. Rubber or plastic numerals, of at least 1 inch in height, shall be
provided by the battery manufacturer for field attachment to permit proper
cell identification. The battery shall have an ampere-hour capacity equal
to at least 125 percent of the station's direct-current requirements
including normal continuous loads plus intermittent loads. Normal
continuous load capacity shall be adequate for an [8-hour] [_____] period.
Intermittent load capacity shall be adequate so that at least [three]
[_____] openings and [three] [_____] closings of each of the station's
associated circuit breakers [and motor-operated] [switches] can occur in
[an 8-hour] [_____] period with no more than [three] [_____] circuit
breaker [or switch] units simultaneously operating. Battery circuits shall
be ungrounded. Batteries shall have a 20-year minimum life and a 5-year no
cost replacement warranty.
2.9.2.2
Battery Racks
Battery racks shall have welded steel frames and rails finished with two
