Circuit Breaker


OK, one big thing I left out of the video, on the breaker you’re replacing there will a number on it. In most cases it will be right on the handle (switch) stating 15 or 20amp or really whatever it may be. This is the amperage, this means if the circuit is drawing more than the stated amperage that the breaker will trip, now once a breakers trips you should wait at least 10 minutes before attempting to reset it. The reason is because the whole circuit has been over loaded and you should let it cool down first.

Never ever keep trying to reset a breaker that has failed. Doing so will provide the circuit with electricity and this is bad. Say the breaker tripped because a rat chewed the insulation on the wires and now there touching. The breaker did it’s job once for you. Don’t think it will keep doing so.


This I seen before, a 15 amp breaker keeps failing, it trips ever so often and now the home owner changes it do a 20 amp thinking that it should work now. You know what, he was right. It did work, meaning that the breaker doesn’t trip for a whole two weeks. Instead the 14/2 15 amp wire in that circuit melted and made a fire. A very bad choice for him.¬†

For a 15 amp circuit uses a 14 gauge wire with a 15 amp breaker

For a 20 amp circuit uses a 12 gauge wire with a 20 amp breaker

As you can see from the picture below that the buss bars are staggered so the breaker that would be on top of the other one right on top of it will not take power from the same busbar (phase)

So in other words, if you were to install a two pole breaker (220 volts) it will take power from both buss bars (both phases) creating 220 volts.

Excellent videos on changing a breaker. I am wondering about a breaker in my panel that I cannot turn off. Obviously, It has not tripped to the off position in the past. I am wondering if this breaker is faulty and needs to be replaced.

What it seems to be is that you have a 220 line and you're trying to use a 120 outlet and A/C. Tell me if I'm right first before we go on, OK.

Hello Dominick, I was wondering if you know how to change a 20 amp outlet to a 15 amp outlet. So heres the story, we had a very old A/C that needed 20 amps and 220 volts. It had a special three hole outlet. Old A/C stoped working a long time ago, we put in a new a/c, and pluged into an outlet in the room other than the unique outlet for the old a/c, because it wouldnt fit. But every time I turn on the a/c plus the a/c in my sisters room, the circuit breaker downstairs clicks off.… Read more »

Thank you so much. Well not something can get done real fast. First you would find the beginning of that circuit and remove all the wires from the outlet or switch. And then on to the next one testing the breaker out each time. Now there can be a lot to it, but this should give you some kind of idea.

Thanks for taking the mystery out of this! I have a very healthy respect for electricity and so, if I don't know what I'm doing 110%, I don't touch it! Therefore, what you showed here with the breaker replacement is awesome. I completely got it!

Having said that, you made a comment about "tracing a circuit to find a short" if the breaker trips continuously. I don't have that problem, but I'd like to know your thoughts about how a person would go about doing that.

Thanks again!<br… Read more »
