A circuit breaker takes a little damage whenever you turn it off and on again. This means that while shutting it off once in a while isn't an issue, repeatedly flipping the switch can harm it and cause an electrical hazard.

How often do circuit breakers need to be tested?

Routine trip testing should be performed every 3 to 5 years. Low-voltage Circuit Breakers should be inspected and maintained every 1 to 3 years, depending on their service and operating conditions.

Can circuit breakers be tested?

Circuit Breaker Testing (also known as 'Trip Profiling') is used to test both the performance of individual switching mechanisms and the timing of the overall tripping system. Circuit Breaker Testing is used to test both the performance of individual switching mechanisms and the timing of the overall tripping system.

Can a breaker trip by too much power?

In most cases, a circuit breaker tripping occurs because of an overloaded circuit. What this means is that a circuit is trying to draw more power than it is designed to carry. The circuit wires will heat up due to the excess power that is being drawn.

What happens if you trip a breaker too many times?

Tripping a breaker too many times or using it as a 'switch' will affect its designed tripping accuracy and you will have to replace it when it does not reset or trip on low current.
