What happens here

Hold the circuit breaker so that the side with the terminal screw is facing downwards. Then, firmly slam or strike the breaker against a hard, flat surface such as a table or shelf. The impact, when applied in this specific orientation, is designed to simulate a fault and trigger the internal tripping mechanism. The video explicitly warns against slamming the breaker in other orientations, as this will not produce the correct result.

Goal: Trigger the circuit breaker's internal trip mechanism through a controlled impact.

to do is just flip the handle in the on position, and slam it on a table, just like this. All right, everybody. So, as you can see, breaker is in the trip position. That's how you know if your circuit breaker works. You can't slam it like this, you can't slam it like this. It has to be with the terminal screw facing down the table, just like this. You're going to hear a click, and boom, guys, it's in the trip position. It works with every single breaker.
