240 Volt Arc Fault Circuit Breaker

The ansi certified and ul listed unit is rated for 120 240 vac and 10 000 air.

240 volt arc fault circuit breaker. A typical 240 volt 30 amp circuit includes a double pole circuit breaker which has two terminals for the two hot wires. A 240 volt 3 wire receptacle has three prongs two hot and one ground to accept a 3 prong plug. The breaker is designed to protect against line to ground arcs line to neutral arcs and series arcs to help protect your home from an electrical fire. Double pole combination afci circuit breaker is intended to mitigate the effects of arcing faults by de energizing the circuit when an arc fault is detected.

An arc fault circuit interrupter or afci is required on certain circuits to protect against electrical fires by cutting power when arc faults occur. The siemens 20 amp 2 in. This is simply a matter of locating the circuit s hot wires black red or blue that are connected to the circuit breaker and the circuit s neutral white wire and replacing the circuit breaker in the panel with the afci type.

Afci arc fault circuit interrupter requirements for homes the arc fault circuit interrupter is designed to turn off an electrical circuit when an arc is detected that can lead to a fire or other hazardous conditions within the range of the protection that the afci is able to detect. A conventional circuit breaker isn t. This breaker is compatible with homeline load centers and csed devices.

The wires usually are black or red but one may be white if it is labeled as hot with a black or red stripe near each end. An afci selectively distinguishes between a harmless arc incidental to normal operation of switches plugs and brushed motors and a potentially dangerous arc that can. An arc fault circuit interrupter afci also known as an arc fault detection device afdd is a circuit breaker that breaks the circuit when it detects an electric arc in the circuit it protects to prevent electrical fires.
