Description / Abstract:

Scope and object 

This Standard applies to switchboards nominally rated at 600 V or less and intended for use in accordance with the Canadian Electrical Code, Part 1 (CE Code, Part 1), the National Electrical Code (NEC), ANSI/NFPA 70, and the Mexican Standard for Electrical Installations (Utility), NOM-001-SEDE. 

In this standard the term switchboard is intended to refer to a dead-front switchboard. 

These requirements do not cover the following switchboard types: preset and dimmer control (theater), live front, railway control or electrification; or constructions intended only for receiving motor control center units. 

These requirements cover switchboards for use on circuits having available rms symmetrical short-circuit currents of not more than 200 000 A.
