The National Electrical Contractors Association (NECA) recently released its 23rd National Electrical Installation Standard publication, the NECA 230-2003, “Standard for Selecting, Installing, and Maintaining Electric Motors and Motor Controllers.”
The guide covers subjects like motor design code letters and characteristics; receiving and storing motors and controllers on job sites; selecting motor branch-circuit, short circuit, and ground fault protective devices; and motor wiring connections.
Charles Trout, the long-time chairman of National Electrical Code-Making Panel 12, was the principal author of NECA 230. The American National Standards Institute approved the guide.
The guide is available in downloadable PDF format at www.neca-neis.org/standards.
