Grounding Conductors
Grounding conductors shall be bare, except where installed in conduit with
associated phase conductors. Insulated conductors shall be of the same
material as the phase conductors and green color-coded, except that
conductors shall be rated no more than 600 volts. Bare conductors shall be
ASTM B 8 soft-drawn unless otherwise indicated. Aluminum is not acceptable.

LIQUID DIELECTRICS
**************************************************************************
NOTE: Select 2 ppm for Air Force projects.
**************************************************************************
Liquid dielectrics for transformers, capacitors, reclosers, and other
liquid-filled electrical equipment shall be non-polychlorinated biphenyl
(PCB) mineral-oil or less-flammable liquid as specified. Nonflammable
fluids shall not be used. Tetrachloroethylene (perchloroethylene) and 1,
2, 4 tetrachlorobenzene fluids shall not be used. Liquid dielectrics in
retrofitted equipment shall be certified by the manufacturer as having less
than [50] [2] parts-per-million (ppm) PCB content. In lieu of the
manufacturer's certification, the Contractor may submit a test sample of
the dielectric in accordance with ASTM D 923 and have tests performed per
ASTM D 4059 at a testing facility approved by the Contracting Officer.
Equipment with test results indicating PCB level exceeding [50] [2] ppm
shall be replaced.
2.22
FACTORY TESTS
**************************************************************************
NOTE: Delete tests that are not applicable to the
project. Refer to TM 5-811-1. Tests must be
justified.
**************************************************************************
Factory tests shall be performed, as follows, in accordance with the
applicable publications and with other requirements of these
specifications. The Contracting Officer shall be notified at least [10]
[_____] days before the equipment is ready for testing.
a.
Transformers: Manufacturer's standard [routine] [design] [and]
[other] tests in accordance with IEEE C57.12.00.
b.
Transformers rated 200 kVA and above: Reduced full-wave,
chopped-wave, and full-wave impulse test on each line [and
