NAMEPLATES
2.3.1
General
Each major component shall have the manufacturer's name, address, type or
style, model or serial number, and catalog number on a nameplate securely
attached to the equipment. Equipment containing liquid-dielectrics shall
have the type of dielectric on the nameplate. Nameplates shall be made of
noncorrosive metal. As a minimum, nameplates shall be provided for
transformers, regulators, circuit breakers, capacitors, meters and switches.
2.3.2
Liquid-Filled Transformer Nameplates
**************************************************************************
NOTE: Coordinate Nameplate C information with the
manufacturer. Select 50 ppm for Army projects and 2
ppm for Air Force projects.
**************************************************************************
Power transformers shall be provided in accordance with IEEE C57.12.00.
Nameplates shall indicate the number of liters gallons and composition of
liquid-dielectric, and shall be permanently marked with a statement that
the transformer dielectric to be supplied is non-polychlorinated biphenyl.
If transformer nameplate is not so marked, the Contractor shall furnish
manufacturer's certification for each transformer that the dielectric in
non-PCB classified, with less than [50] [2] ppm PCb content in accordance
with paragraph LIQUID DIELECTRICS. Certifications shall be related to
serial numbers on transformer nameplates. Transformer dielectric exceeding
the [50] [2] ppm PCB content or transformers without certification will be
considered as PCB insulated and will not be accepted.

CORROSION PROTECTION
2.4.1
Aluminum Materials
[Aluminum shall not be used in contact with earth or concrete. Where
aluminum conductors are connected to dissimilar metal, fittings conforming
to UL 486A-486B shall be used.] [Aluminum shall not be used.]
2.4.2
Ferrous Metal Materials
2.4.2.1
Hardware
Ferrous metal hardware shall be hot-dip galvanized in accordance with ASTM
A 153/A 153M and ASTM A 123/A 123M.
2.4.2.2
Equipment
**************************************************************************
NOTE: A 120-hour test will be specified in a
noncorrosive environment and a 480-hour test will be
specified in a corrosive environment.
**************************************************************************
Equipment and component items, including but not limited to transformers
and ferrous metal luminaires not hot-dip galvanized or porcelain enamel
finished, shall be provided with corrosion-resistant finishes which shall
