What does AFCI stand for?

AFCI stands for Arc Fault Circuit Interrupter. This device is designed to detect and interrupt arc faults, which are unintentional electrical discharges that can occur in wiring and connections where insulation has deteriorated or where there's a poor connection. The AFCI is a critical component in modern electrical systems because it enhances safety by preventing electrical fires caused by these dangerous arcs.

The introduction of AFCIs in residential wiring has significantly reduced the risk of fire. They work by continuously monitoring the electrical circuit for signs of arcing, and when an arc fault is detected, the AFCI quickly shuts off the electrical flow, mitigating the threat of fire.

This technology is particularly important in areas of a home where flammable materials are present or where electrical devices are frequently plugged and unplugged. Ensuring that AFCIs are installed in appropriate circuits is a key requirement in current electrical codes to enhance residential safety.
