FAQ:

How does a circuit breaker work?

Circuit breakers detect excessive current flowing through a circuit. When this happens, they “trip,” interrupting the flow of electricity to prevent damage to the circuit and appliances or equipment connected to it.

What are the common voltage ratings for used circuit breakers?

Common voltage ratings for circuit breakers include 120V, 240V, 480V, and 600V, among others. The specific voltage rating depends on the requirements of the electrical system.

What are some signs that circuit breaker needs attention or replacement?

Signs of a faulty or failing circuit breaker include frequent tripping, a buzzing or humming sound, a burning odor coming from the breaker panel, or visible signs of damage such as scorch marks. If you notice any of these signs, it’s important to have a qualified electrician inspect the circuit breaker promptly.
