What does AFCI stand for?

The correct definition of AFCI is Arc-Fault Circuit Interrupter. AFCIs are devices designed to detect arc faults, which are unintended electrical discharges that can generate heat and potentially ignite a fire. By monitoring the electrical circuit for these hazardous conditions, AFCIs enhance safety in residential and commercial settings by automatically disconnecting power when an arc fault is detected.

AFCIs are particularly important in areas where electrical cords and devices might become damaged or frayed, as well as for protecting wiring in walls and ceilings from conditions that could lead to serious fires. This differs significantly from other terms, such as those associated with frequency in electrical contexts or other types of protection devices. Understanding AFCIs and their role in electrical safety is crucial for anyone involved in electrical installations or maintenance.
