WIRING SCHEMES AND GROUNDING

Nuclear facilities rely on standardized wiring schemes to provide both single-phase
and three-phase power distribution systems and protective grounds to insure
safe operation.

 

Introduction

Many advisory boards exist to insure the standardization of electrical installations in accordance
with accepted designs and safe practices. The Institute of Electrical and Electronics Engineers
(IEEE) and the American National Standards Institute (ANSI) are two advisory boards that have
published numerous standards. These standards are utilized by the Department of Energy and
the nuclear industry. However, for a day-to-day practical guide for noncritical installations, the
recognized guide is the National Electrical Code Handbook (NEC), published by the National
Fire Protection Association and endorsed by ANSI. The NEC Handbook is the primary source
of much of the material presented in this chapter and may serve as a ready reference for specific
questions not covered in this fundamental discussion.
