Exothermic Welding. Exothermic welds must be Cadweld, a registered trademark of Erico
Products, Inc. of Cleveland, Ohio, or ThermOweld, a division of Continental Industries, Inc.
of Tulsa Oklahoma or equivalent.
Ground Clamp. Used for conduit or water pipe, for instance. Burndy GAR style UL clamp
with two- hole provisions for long barrel multiple crimp two-hole lugs or equivalent.
Conduit. Conduit requirements vary due to state and local construction codes. The local
engineering firm determines what is required depending on the site type and jurisdiction.
Consider material and labor costs when selecting a conduit type as long as all applicable
codes are followed.
Metal conduit. (At a minimum) UL listed galvanized rigid steel conduit (minimum size: 1-
1/2-inch trade size) with UL listed fittings. Steel compression fittings, watertight fittings,
and bonding to grounding conductors at both ends are required. Do not use set screw
settings.
PVC conduit and fittings. Schedule 40 (minimum). Do not use EMT conduit for
underground applications.
When conduit is visible and there is no method to determine the contents (for example,
utility shafts in a building), label the conduit as power (with voltage), Telco service, or
ground.
