Testing Arc Fault (AFCI) Breaker on Real Load

Показать описание
Ever wondered how well AFCI breakers work? Here was a test I did using a 800W resistive load (so only 6A!) showing how an AFCI tripped due to a loose terminal on a plug.

(Note - breaker was plugged into another GFCI for additional protection here, and due to camera zoom it looks like I'm closer, don't try at home etc!)

I just had to replace one yesterday due to a failure after an arc was created in a ceiling fan wire that I found. Replacement was $65.

I just tried this and posted a video. It took 20 mins to trip

What if the breaker sparks when turned on? Could it be a faulty breaker?

I’m surprised it tripped since its a BR breaker they usually don’t.

Wow, that looks useless! Glad they are both expensive AND required!
