Revised Standard for Installing and Maintaining Medium-voltage Cable
November 03, 2014The National Electrical Contractors Association (NECA) and the National Cable Splicing Certification Board (NCSCB) released NECA/NCSCB 600-2014, Standard for Installing and Maintaining Medium-Voltage Cable the latest in a series of revisions for National Electrical Installation Standard (NEIS) in 2014.
NECA/NCSCB 600-2014 is the latest revision in the National Electrical Installation Standards series published by NECA. This standard has been revised to reflect the latest provisions and requirements in the NEC and other applicable standards including NFPA 70 Standard for Electrical Safety in the Workplace. It includes periodic routine maintenance and troubleshooting procedures for these types of power cables. This revision also includes recommended practices for testing of medium voltage cables in accordance with IETA standards. This standard covers periodic routine maintenance and troubleshooting procedures for medium-voltage cable, and special procedures used after adverse operating conditions such as a short circuit or ground-fault.
This standard describes installation procedures for shielded and non-shielded solid-dielectric medium-voltage cables rated from 2001 Volts to 35,000 Volts AC and installed in conduits or ducts, or direct buried. This publication applies to single-and multi-conductor cables used for distributing power for commercial, institutional and industrial loads in nonhazardous locations both indoors and outdoors.
“Splicing and terminating medium voltage cables is a critical step in the safe performance of the final installation” says Michael Johnston, NECA executive director of Standards and Safety. “This standard provides the essentials not only for quality installation, but essentially procedures for high-potential testing these cables prior to energizing.” The standard addresses cables terminated with kits in accordance with manufacturer’s directions, and terminations of existing cables terminated or spliced without use of a kit.
