Understanding Circuit Breakers

Before delving into the lifespan and replacement of circuit breakers, let’s take a moment to understand how they work. A circuit breaker is an electrical switch that is designed to protect an electrical circuit from damage caused by excessive current flow.

When an electrical overload occurs or a short circuit is detected, the circuit breaker trips, cutting off electricity flow to the circuit and preventing any further damage. This is achieved through a mechanism that includes a bi-metal strip or an electromagnet, which senses the current passing through the circuit. When the current exceeds the predefined limit, the strip or the magnet triggers the breaker to switch off.

Circuit breakers are typically installed in electrical panels, commonly known as breaker boxes. These panels serve as the central hub for controlling and distributing electrical power throughout a building or residence. Each circuit breaker in the panel corresponds to a specific electrical circuit, such as those that power lights, outlets, appliances, or specific areas of the building.

It’s important to note that circuit breakers should not be confused with fuses. While both perform the same function of protecting electrical circuits, fuses need to be replaced when they blow out, whereas circuit breakers can be reset after they trip.

Now that we have a basic understanding of how circuit breakers function, let’s explore their lifespan and when they may need to be replaced.
