Electrical circuit breakers play a crucial role in protecting our homes from electrical overloads and short circuits. Understanding the basics of circuit breakers is important for every homeowner.

Most household circuits are rated either 15 amps or 20 amps. The common rating for household circuit breakers is 15 amps. This means that the circuit breaker can handle up to 15 amps of current flow before tripping and disconnecting the circuit.

It's important to remember that circuit breakers should only be loaded up to about 80% of their rated capacity to prevent overheating and potential fires. Knowing the rating of your circuit breakers and not overloading them will help keep your home safe from electrical hazards.
