Would an AFCI circuit breaker work as a service or feeder protection device?
No, because they are limited by UL to 15A and 20A, 120V. Are the electronics in AFCI devices subject to the damaging effects of high-voltage surges? And if so, do they continue to energize the circuit giving the false impression that they are working properly? Yes, the electronics in AFCI devices are subject to the damaging effects of high-voltage surges, just like a GFCI circuit breaker. The instructions supplied with both GFCI s and AFCI s stress that they should be tested monthly to ensure that they are operational. NOTE: The AFCI UL standard was recently revised to raise the surge voltage test from 4kV/2kA to 6kV/10kA and all permanently connected AFCI s must meet this requirement by July 15, 2004. I read there s a nuisance-tripping problem with AFCI devices. Has this problem been resolved yet? The major problem is that some installers do not yet understand how the AFCI circuit protection device operates. If there is a neutral-to-ground connection on the load side of the circuit br
