circuit breaker 2

[yusang]

Is there any way to identify that the circuit breaker is use in ac or dc circuit ? Thanks in advance .

Generally that would depend on what the device that is conneted to the circuit that the breaker controls is.

If there are no labels to indicate AC or DC, you can use a multi-meter, like a Fluke, and take a simple reading.

There are simple circuit tracers available at Home Depot, etc for around $40. You plug it into an outlet, then take the probe to the breaker box. By slowly lowering the volume on the probe until it only reacts when held directly over 1 breaker will identify the breaker in use.
