For members of the power and communications industries who can’t ever seem to "get the cord long enough," NEMA has released a new application guide that offers an alternate way to direct conduit around an obstacle. “Conduit-in-Casing” explains the process of laying power/communications cables under a surface obstruction, including listing types of casings, conduits, and spacers used, and detailing how the cable laying process works.
The guide was developed by NEMA’s Polymer Raceway section. It specifies the use of Schedule 40 PVC pipe, DB120 conduit, Heavy Wall reinforced fiberglass, Heavy Wall conduit, and Type C telephone duct. The guide is available for free download by visiting www.nema.org/conduitfittings/ and clicking on Standards and Other Publications.
