The breaker goes ahead of

I think I can help you with that!

The phrase "the breaker goes ahead of" is likely referring to a specific concept in the context of electrical systems. In this case, I'm going to take a guess that you're talking about a circuit breaker.

A circuit breaker is an electrical device designed to interrupt the flow of electrical current in an electrical circuit. When a breaker "goes ahead of" something, it means it's acting as a protective device to prevent a fault or overload from causing damage to the circuit or equipment.

In other words, the breaker is positioned ahead of the load or equipment it's protecting, and it will trip or shut off the power supply if it detects an abnormal condition, such as an overload or short circuit.

Am I correct?
