Arc Flash Reduction Breaker

Question asked by j_w_hines on Mar 8, 2019

NEC 240.87 for arc reduction circuit breakers of 1200A or more, when applying to an emergency generator with life safety and if accidently left 'on' could cause an unwanted trip.  Is there an exception or is there another section that requires monitoring of the maintenance switch setting?  For the high rise application, I will have the fire panel monitor the switch and wondered if anyone else has run into this?
