eli5: Mains, Neutral and ground, which plugs do circuit breakers attach to?

Question

I’m wondering which ones it checks the p.d over to break the circuit or if thats how it works at all.

In: 1

Answer 1

the “hot” line is the one the breaker is actually wired into.

breakers work off current. inside the breaker is an electromagnet. when the current gets too high, that magnet pulls on a mechanism that breaks the circuit.
