What protection is provided for line-to-ground arcing for CAFI breaker?

QO and HOMELINE

Resolution:

The UL 1699 Standard requires arcs of 5 A and above be detected line-to-ground. It is true that the SqD AFCI and others have ground fault sensing down to below 50 mA. We consider this good protection because these low current leakages are frequently the beginning of a larger arcing problem.
