3.00 EXECUTION
3.01 PREPARATION
Completely swab raceway system before installing conductors. Do not use cleaning agents and
lubricants which have a deleterious effect on the conductors or their insulation.
3.02 INSTALLATION
A. GENERAL
1. Conductors shall be continuous from terminal block to terminal block without splice.
Condulet type fittings shall not contain splices. No splicing of conductors shall be
performed in any below ground structure.
2. Splice only in junction or outlet boxes for branch circuits. Splices for all other circuits shall
be disallowed. Neatly train wiring inside boxes, equipment and panelboards. Pull
conductors into a raceway at the same time and use U.L. listed, water based, wire pulling
lubricant for pulling No. 4AWG and larger wire. Install raceway first as a complete system
without conductors. Do not install pull wires and conductors until the raceway system is in
place.
3. Grouping conductors together into one conduit shall not be allowed where the plans
indicate the conductors to be placed in separate conduits. Each home run shown on the
plans shall be in its own conduit.
4. Properly support cables in accordance with the NEC and manufacturer’s
recommendations in all raceways. Provide strain relief as required.
5. The cable shall not be bent to a radius no smaller than the manufacturer cable’s minimum
bending radius.
6. Sharing of neutrals in not allowed.
7. Verify all cables and conductors by field telephone communications. Any conductor not
tested as specified will be de-terminated, tested and re-terminated at the Contractor’s
expense. Payment will not be made for the work until the test has been done.
