Arc Fault Breaker Wiring. An arc fault circuit interrupter also known as an arc fault detection device afdd is a circuit breaker that breaks the circuit when it detects the electric arcs that are a signature of loose connections in home wiring. A combination arc fault circuit breaker is not equivalent to a dual function circuit breaker.
If the arc fault breaker still trips the electrician then needs to track down the cause by going into each switch receptacle and light box to look for a wiring problem. If there is a bare ground wire making contact with the neutral conductor the breaker will trip instantly as soon as a load exceeding 40 watts is applied to the circuit. An arc fault circuit interrupter also known as an arc fault detection device afdd is a circuit breaker that breaks the circuit when it detects the electric arcs that are a signature of loose connections in home wiring.
Loose connections which can develop over time can sometimes become hot enough to ignite house fires.
Afci protection is provided by either an afci circuit breaker installed at the electrical panel or by a receptacle specifically identified as providing arc fault protection. If there is a bare ground wire making contact with the neutral conductor the breaker will trip instantly as soon as a load exceeding 40 watts is applied to the circuit. Arc fault circuit interrupter afci is a protective device which detects the electric arc in the circuit and automatically break the circuit cutoff power supply to prevent electrical fire. With ever changing electrical code requirements a circuit breaker with the ability to provide both arc fault protection as well as ground fault gfci protection was long overdue.
