I've got an auto resetting circuit breaker which I do not know its amp rating.

How could I test it to find out at what amps it trips?

You would need some type of variable load and an inline ampmeter to continuously monitor the current being drawn as the load is changed. OHMs law states E=IxR (Voltage = Current X Resistance) therefore I=E/R.

My amp meter only goes to 10 amps - so I think I'll just get a new circuit breaker.

Cheers,
