NECA publishes first NEIS covering line construction

NECA, Bethesda, Md., recently published the 21st volume in its series of National Electrical Installation Standards (NEIS). NECA/MACSCB 600-2003, Recommended Practice for Installing and Maintaining Medium-Voltage Cable (ANSI) covers shielded and non-shielded, solid-dielectric, medium-voltage cables rated from 600V to 69,000VAC. It describes installation procedures for single- and multi-conductor cables installed in conduits, ducts, or direct-buried, in both indoor and outdoor applications. The publication also defines 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.
