Product Description

An Arc Fault Circuit Breaker (AFCB), also known as an Arc Fault Detection Device (AFDD), is a specialized circuit breaker designed to identify and deactivate electrical arcs that pose a fire hazard. Unlike standard circuit breakers, which are triggered solely by overloads or short circuits, AFCB possess heightened sensitivity to detect arc faults.

Key information regarding AFCB includes the following:

Functionality:
AFCB operates by recognizing the distinct characteristics of an arc fault, which occurs when electrical current bypasses the intended load and arcs between conductors. Upon detection, the AFCB interrupts the electrical flow to prevent the potential ignition of a fire.

Regulatory Requirements:
AFCB is mandated in numerous new residential constructions and are increasingly being integrated into older homes. The specific requirements for AFCB installation are determined by the building codes applicable within the respective jurisdiction.

Troubleshooting a Tripping AFCB:
In instances where an AFCB frequently trips, it is advisable to disconnect appliances, switch off lights, and examine the wiring for any issues. Should the AFCB continue to trip despite these measures, it may indicate a malfunction or obsolescence, necessitating replacement.
