Re: GFCI on arc fault circuit
I don't think there is any way to protect ourselves from the service call that is caused by a burned out light bulb, the tripped breaker that doesn't indicate, the S-Type Fusestat that isn't seated all the way. . .
I've even had a restaurant prep kitchen, in the height of pre-lunch rush, call me in to simply turn on the light switch for them (a loaf of bread, falling off a shelf, had brushed the switch during its decent).
