Why does the generator GFCI trip on some generators when used with a transfer switch?
Download Honda Generator Service Bulletin NOTE: AFFECTED MODELS ONLY INCLUDE: HONDA EB series Models EB3500XK1, EB5000XK1, EB6500SX, EB12DAG, Arctic Cat Model 1999 AC7500GD2EB, some models from Briggs and Stratton and Cummins. These generators listed above are intended for industrial/contractor/jobsite applications which are subject to OSHA requirements. These “contractor grade” generators have their neutral wire bonded to the ground wire to pass OSHA inspection on job sites. Since home and building main load centers also have the neutral bonded to ground, a loop is created, comprised of the neutral wire and the ground wire. A small amount of current is induced in this loop by the running generator. and since the neutral wire passes through the ground fault sensor, the GFCI senses this induced current and trips the main circuit breaker in the generator. When using these neutral bonded generators to power a house or building through a transfer switch, the neutral bond wire on the genera
