Two different technologies protect against two different types of hazard. Ground fault circuit interrupter (GFCI) devices protect people from shock by opening a circuit at a low threshold of leakage ...

Unlike a conventional circuit breaker, which detects overloads and short circuits, an arc fault circuit interrupter (AFCI) uses advanced electronic technology to sense different arcing conditions.

Dear James: I am concerned about a fire from an electrical issue in my older house. What are the differences among fuses, breakers, GFCI and AFCI, and which are best? — Peggy T. Dear Peggy: You are ...

The United States' National Electrical Code (NEC) recently expanded Arc-Fault Circuit Interrupter (AFCI) requirements (see "Arc-Detecting Circuit Breakers Will See Wider Use" at ...
