an electrical safety device designed to detect and mitigate the risk of arc faults in electrical circuits, which can lead to electrical fires

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.

  • ChatGPTThe electrician recommended installing an arc-fault circuit interrupter to improve the home's safety.
  • The AFCI tripped immediately when it detected an arc fault in the electrical wiring.
  • To prevent potential fires, the new house was equipped with an arc-fault circuit interrupter in all bedrooms.
  • Installing an AFCI is now required in many parts of the home, including living rooms and hallways.
  • After the power was cut by the arc-fault circuit interrupter, the technician inspected the wiring for damage.
