New rules for Ground Fault Circuit Interrupters

摘要

This presentation will cover Ground Fault Circuit Interrupters (GFCIs) as defined under OSHA General Industry Electrical Standard S29CFR1910, Subpart S [1], effective Oct 2008. These recent OSHA changes outline GFCI Requirements for General Industry temporary wiring installations that are used during construction-like activities including certain maintenance, remodeling or repair activities, involving buildings, structures or equipment. This General Industry rule also covers voltage other than 125 volt, single-phase receptacles (high voltage applications). We will present the history of GFCI Standards, GFCI internal make-up and knowledge that will save lives. We will also cover applications up to 600V, 80A, with examples from manufacturing/process plants, entertainment examples, municipal/institutional applications and more.
