What is an "arc-fault circuit interrupter"?

An arc-fault circuit interrupter (AFCI) is a safety device designed to detect and prevent electrical fires caused by arc faults. An arc fault occurs when electricity jumps across a gap in a circuit, which can cause sparks or heat, leading to fires. The AFCI monitors the electrical circuit for signs of these dangerous arcs and automatically shuts off the power when detected. This device is commonly installed in outlets, circuit breakers, or fuse panels and is used to protect homes and buildings, particularly in areas like bedrooms and living rooms where electrical fires are more likely to occur.
