Electrical Conduit

Follow these general precautions for conduit installation:
(1) Conduit cutoffs must be square. Cutoffs must be made by a cold cutting tool, hacksaw, or
by some other approved means that does not deform the conduit ends or leave sharp edges.
(2) All conduit fitting threads, including factory-cut threads, must be coated with a metal-bearing
conducting grease, such as Crouse-Hinds STL or equivalent, prior to assembly.
(3) Temporarily cap the ends of all conduit run runs immediately after installation to prevent
accumulation of water, dirt, or other contaminants. If necessary, swab out conduits prior to
installing the conductors.
(4) Install drain fittings at the lowest point in the conduit run; install seals at the point of entry
to the GC Controller's purged housing to prevent vapor passage and accumulation of
moisture.
(5) Use liquid-tight conduit fittings, such as Myers Scru-Tite or similar, for conduit which is
exposed to moisture.
When conduit is installed in hazardous areas (e.g., areas classified as NEC Class I, Division 1,
Groups C and D), follow these general precautions for conduit installation:
(6) All conduit runs must have an explosion-proof sealing (potting) fitting located within 18
inches (45.5 centimeters) distance from the conduit entrance to explosion-proof housings.
(7) The conduit installation must be vapor tight, with threaded hub fittings, sealed conduit joints
and gaskets on covers, or other approved vapor-tight conduit fittings.
