“The AFCI is a device that monitors current traveling through a circuit and that trips when an abnormal waveform is detected that could mean an arc or spark,” said Thomas Domitrovich, product manager at Cutler-Hammer/Eaton Corp., Moon Township, Pa. AFCIs detect arcing faults and open the circuit to stop the flow of electricity. “AFCIs employ electr...
According to Ode, AFCIs were designed and tested to recognize the unique characteristics of an arcing fault and trip when these faults are detected. However, there is ground-fault protection built into AFCI circuit breaker devices and that tripping level will vary depending on the manufacturer. There are a few procedures an electrical contractor ca...
The NEC is developed and periodically reviewed by more than 5,000 volunteer committee members with a wide range of professional expertise.

210.12(B) DWELLING UNIT BEDROOMS. All 120-volt branch circuits supplying 15- and 20-ampere outlets installed in dwelling unit bedrooms shall be protected by a listed arc-fault circuit interrupter, combination type installed to provide protection of the branch circuit.
A point on the wiring system at which current is taken to supply utilization equipment. (Article 100 Definition)
The NEC requires that all 120-volt, 15- and 20-ampere outlets in bedrooms be AFCI-protected, whether they are for receptacles, luminaires (lighting fixtures), ceiling fans, hard-wired smoke alarms or other utilization equipment. With 240-volt equipment such as baseboard heaters and through-wall air conditioning units, it isn’t required by the Code ...
Arc-fault circuit interrupters are designed to prevent a type of electrical hazard that conventional overcurrent protective devices don’t guard against very well. An example would be a frayed lamp cord that exposes the copper wire inside, creating a low-energy electrical arc to some other piece of nearby grounded metal. AFCIs protect against the fo...
