What does the acronym AFCI stand for?

AFCI stands for Arc Fault Circuit Interrupter. It’s a protective device in residential wiring that detects dangerous electrical arcs—such as from damaged insulation or loose connections—and quickly shuts the circuit off to prevent fires. This arc-detection capability is what sets AFCIs apart from other protections, like GFCIs that guard against shock from ground faults. The other phrases don’t describe a real protective device that detects arcing, so they don’t match what AFCI refers to.
