05/19/2015 9:00AMSign-up to receive press releases.

ROSSLYN, Va.—The National Electrical Manufacturers Association (NEMA) published NEMA PRP 1-2014 Guidelines for Conduit-in-Casing Construction. This document presents conduit-in-casing construction as a technically sound solution to the problem of laying power/communication cables under a surface obstruction (highway, runway, rail bed, river, etc.) without disrupting traffic roadbed, rail bed, or riverbed.

NEMA PRP 1, which was developed by the Polymer Raceway Products Technical Committee, describes the types of casings most often used as well as the advantages of concrete-in-casing construction for organization of conduits, protection of mission-critical cables, and longevity. It is useful in the construction, utilities, and electrical contracting industries.

NEMA PRP 1-2014 may be downloaded at no charge on the NEMA website.
