You need both to prevent fire and accidental shock. Fortunately, you can install both at the same time for all of your receptacles by using GFCI+AFCI circuit breakers. Unfortunately, they are expensive.
- mturmon 15y agoAll true, and also: GFCI breakers will not substitute for the dual breakers used in many panel boxes, they are too big. And, use of GFCI breakers is not compatible with three-wire circuits used in many locales in the US, at least. (What I mean is, two hot wires of opposite polarity sharing a common grounded conductor, allowing to run two circuits over three wires.)
