NOTE: If aluminum conductor is permitted (not
excluded), include requirement for adjusting the

Also give detailed instructions as to materials and
methods required for splicing and terminating
600-volt wires and cables with regard to the
material used at bus or other connection point.
Circuit identification shall be as indicated on the
drawings. However, for projects within the

Base Complex (including the Shipyard and SUBBASE)
and other activities when customer requires it,
conductors shall be copper. There are other
instances when you may want to consider copper only
(customer request, matching existing with small
quantity, etc.). If copper only is specified,
delete subparagraphs entitled "Wire and Cable
Conductor Sizes" and "Aluminum Conductors" and other
references to aluminum conductors.
If U.R.D. type cable is desired, specify that the
construction shall include an extruded jacket to
prevent corrosion or displacement of the concentric
wire shield.
**************************************************************************
Conductor and conduit sizes indicated are for copper conductors unless
otherwise noted. Insulated conductors shall have the date of manufacture
and other identification imprinted on the outer surface of each cable at
regular intervals throughout the cable length. Wires and cables
manufactured more than [12] [24] months prior to date of delivery to the
site shall not be used.
