BASIC MATERIALS AND METHODS
approval for splicing prior to installation of feeder(s). Refer to Splicing
Methods listed below.
Do not pull conductors into raceways until raceway system, including all
outlets, cabinets, bushings and fittings, is completed. Verify that all work of
other trades which may cause conductor damage is completed. Use only
U_L. approved cable lubricants when necessary. Do not use mechanical means
to pull conductors No. 8 or smaller.
