Questions about: circuit-breaker - страница 2

Wire design is usually based on minimizing the length of wire needed. By putting all lights on one circuit and outlets on another, it would require more wire than would normally be used and also cause needless inconvenience if the light circuit tripp
If your device is drawing too much power, and is causing the breaker to trip. It means the device is too large for the circuit, and the breaker is doing the job it was designed to do. Making an "automatic breaker turner on-er" is not likely the best
Manually flipping a breaker, especially without a significant active load, should never melt a breaker. A melted breaker indicates a large heat build-up. This could be a defective breaker but is more likely a bad connection, producing resistance, whi
It could have to do with the trip curves of the breakers, and/or the ambient temperature differences between panel locations. For example, let's say all the circuits on Phase A are drawing 3 times the rated current. The trip curve for these breakers,
We redid our bathrooms and had an electrician come in and put in new wiring for outlets, heater/fan/lights and heated floors. He had to replace the electrical panel, because the house is older (1956) and didn't have enough space to accomplish the tas
My mother in law recently replaced her 4 burner Frigidaire range and is often popping her breaker when she is cooking for a large party - ie 4 burners going and oven. I checked the specs for the range and they suggest a 50A breaker. The electrical ci

I have an old 225 Amp 30 space commercial flush mount sub-panel in my home with bolt on breakers that has worked for years. Now, there's 120v on one bus and 0 volts on the other bus. When I remove the leads from the bus, I get 120v on each lead, so t
As other comments have stated, it is likely an AFCI or (more likely) a GFCI breaker. Can you determine where that circuit goes? Knowing its termination would help, since some areas, like bathrooms and laundry rooms, are more likely to validate that.
