What is Arc Fault Breaker?

Arc Fault Circuit Interrupter(AFCI):

    Devices called arc-fault breakers are made to recognize the distinct electronic sign of an arcing or sparking connection. It detects any unusual oscillations and trips the breaker, effectively stopping a fire. The arcing may be caused by a nail pushed through or hammered into a live wire, a mouse chewing the wire, a corroded or worn-out electrical cord, or a defective device with incorrect wiring.

    A circuit breaker found in your electrical panel is termed an AFCI breaker. Ideally, it is a standard circuit breaker with the additional capability of cutting off electricity to the entire circuit if it detects any dangerous arcing. An AFCI receptacle is distinguished by a special, colored test-button that is located next to its handle.

How does an Arc Fault Breaker work?

    The Arc Fault Circuit Interrupter(AFCI) breaker circuitry continuously tracks the flow of current across the wiring system. To distinguish between desired and undesirable arcing circumstances, AFCI uses detection systems. The AFCI breaker trips the internal contacts during an unwelcome arcing, de-energizing the circuit.

    The highly developed AFCIs can quickly discern between purposeful and accidental arcing and know how to respond in each case.

How to install Arc Fault Breaker?

To install an arc fault circuit breaker, follow these instructions:

1. By turning off the main circuit breaker, you can turn off the electricity in your entire home.

2. After confirming with a circuit tester that the power is off, remove the panel cover.

3. By disconnecting the black wire from the breaker, remove the old circuit breaker.

4. Coil the white wire from the AFCI breaker and connect it to the neutral bus bar.

5. Reinstall the panel cover, connect the power, and then install the AFCI breaker.

6. Test the Arc fault breaker.
