at the terminations, or requires that only copper conductors be
provided between components of equipment, the Contractor shall
provide copper conductors, or necessary splices, splice boxes, and
other work required to satisfy manufacturer's requirements.
2.1.4
600 Volt Wire Connector and Terminals
Shall provide a uniform compression over the entire contact surface.
Solderless terminal lugs shall be used on stranded conductors.
a.
For use with copper conductors:
UL 486A-486B.
[b.
For use with aluminum conductors: UL 486A-486B. For connecting
aluminum to copper, connectors shall be the circumferentially
compressed, metallurgically bonded type.]
2.1.5
600 Volt Splices
Provide splices with a compression connector on the conductor and by
insulating and waterproofing using one of the following methods which are
suitable for continuous submersion in water and comply ANSI C119.1.
a.
Provide cast-type splice insulation by means of molded casting
process employing a thermosetting epoxy resin insulating material
applied by a gravity poured method or by a pressure injected
method. Provide component materials of the resin insulation in a
packaged form ready for convenient mixing without removing from
the package.
b.
Gravity poured method shall employ materials and equipment
contained in an approved commercial splicing kit which includes a
mold suitable for the cables to be spliced. When the mold is in
place around the joined conductors, prepare the resin mix and pour
into the mold.
c.
Provide [heavy wall] heat shrinkable splice insulation by means of
a thermoplastic adhesive sealant material which shall be applied
by a clean burning propane gas torch.
d.
Provide a cold-shrink rubber splice which consists of EPDM rubber
tube which has been factory stretched onto a spiraled core which
is removed during splice installation. The installation shall not
require heat or flame, or any additional materials such as
covering or adhesive. It shall be designed for use with inline
compression type connectors, or indoor, outdoor, direct-burial or
submerged locations.
2.1.6
Medium Voltage Cable
Cable (conductor) sizes are designated by American Wire Gauge (AWG) and
Thousand Circular Mils (Kcmil). 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 cable length.
Wires and cables manufactured more than [24] [12] months prior to date of
delivery to the site shall not be accepted.
