ANSI E1.19 is intended to offer guidance in accordance with existing applicable standards on how to select, install, use and maintain ground fault protection devices in the entertainment industry to protect persons from shock and persons and property from fire. This is a revision of the 2009 version that incorporates new information about avoiding nuisance tripping and offers new recommendations for ground fault protection on higher ampacity circuits.
ANSI E1.23 offers guidance on planning and carrying out fog effects so that recognized exposure levels are not exceeded, fire and egress hazards are not created, false alarms don't summon the fire brigade, and fog effects are executed as they are designed, performance after performance. This is a reaffirmation of the 2010 version. There are no substantive changes.
