ESTA - ANSI/ESTA E1.19
Recommended Practice for the use of Class A Ground-Fault Circuit Interrupters (GFCIs) intended for personnel protection in the Entertainment Industry
|Publication Date:||1 January 2015|
The scope of this document is to recommend a practice for the safe use of Class A Ground Fault Circuit Interrupters (GFCIs) on 120-240 VAC single and three phase 60 Hz circuits with current ratings of 100 ampere or below where the voltage to ground does not exceed 150 VAC (hereinafter referred to as 15 to 100 ampere, 120-240 VAC, single and three phase circuits). GFCIs are used for personnel protection in entertainment applications encompassing places of assembly; the production of film, video, and broadcast; theatrical productions; carnivals; circuses; fairs; and similar events in North America.
Informational Note: Systems that are 230 VAC to ground (e.g., European power systems) are outside of the scope of the class A GFCI Standard (UL 943) so they are outside the scope of this E1.19 Recommended Practice.
