Would having a gfci on the end of an afci protected general lighting circuit cause the gfci to be more sensitive?
Homowner reports two outdoor gfci 15 amp recepts. trip on his skill saw. Both circuits are afci protected general lighting circuits and end with gfci.
I had him try his saw on the non-afci dedicated headbolt heater circuit, one of the non-afci SA circuits and also the non-afci bath gfci recept. circuit; he reports no problem.
My understanding of the gfci is that it monitors return current and trips if the difference between line and load exceed 6 miliamps. Shouldn't have anything to do with breaker or other loads upstream from gfci, should it?
I'll go replace both gfcis Monday, but would appreciate any input if you've had something similar happen.
