1. Structure. The enclosure shall be free-standing and floor supported, with front and/or

rear access as specified. An adequate number of anchor bolt holes shall be designed
to place the base in direct contact with the foundation when bolted. The flatness of
the floor surface upon which the equipment is installed shall deviate no more than

0.125 inches per 10 feet in any direction. All doors shall be formed from sheet stock,
provided with sufficient hinges to support the door, and able to swing open more than
90 degrees. Front doors shall be supplied with a lockable handle. Rear doors, if
applicable, shall be supplied. All door locks shall be keyed alike, with one key
supplied for each lock. All panel covers shall be formed type, and secured with
screws as necessary. The sheet steel used for the finished assembly shall be
degreased and thoroughly cleaned through a minimum five stage aqueous process.
The finish shall be ANSI-61, light gray, electrostatically charged powder paint over a
phosphate coating, at an average of 2.0 mils thick. Finish shall be suitable for indoor
and outdoor environments, enclosure Type as specified.

2. Bus. Distribution main bus shall be silver plated copper and have a maximum

current density of 1000 amperes per square inch. Main bus shall be rated for [1200 |
3000 | 4000] amperes and braced appropriately.

3. Wiring. Control wiring shall be UL 1015 rated for 600 volt. Current transformer

wiring terminations, where applicable, shall be ring type; shorting terminal blocks
shall be included where applicable.
Control wires shall include identification every eight (8) inches or less, permanently
marked with wire designations. These designations shall include the device and
connection point where the wire is terminated. All wire markings shall be permanent
and not noticeably fade or smudge. Low level signal circuits shall be separated and
