Testing Arc Fault (AFCI) Breaker on Real Load
Вставка

- 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.
cool now do it with a GFCI breaker
I just tried this and posted a video. It took 20 mins to trip
Interesting! This is www.tiktok.com/@stevenj120volts/video/7288374556442496286 right? You look to have an even beefier load too. I have a longer video at ua-cam.com/video/TpUJBA5Trvg/v-deo.html that explains what they look for. That video has a link to a paper showing the "hot terminal" problem too, AFCI won't always stop/detect that it seems, so I think your results are somewhat "expected" (that small red arc won't always trip). For me there was a noticeable flash-over arc through the carbon path that often caused the trip.
Yes I had 13-14 amps. Thanks I will watch you longer video later today. Just to introduce myself.... I am a master electrician with 83k followers on tik Tok doing mostly hands on electrical demonstration like this video. I just started trying to post on UA-cam .
@@ColinOFlynn I also plan on trying with Square D QO this weekend
What if the breaker sparks when turned on? Could it be a faulty breaker?
Works for dc current?
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!
Yeah. You can say that once your house burns due to an electrical loose connection.
They’re not just intended to help with issues like that, but also puncturing wire in a wall with a nail or something; saving you from a fire
