How many amps does a circuit breaker use?

Why Do Breakers Trip? The circuit and circuit breaker that you tripped have a capacity of 15 amps, or 1,800 watts (15 amps x 120 volts = 1,800 watts). The lights drew 360 watts, or a measly 3 amps (360 watts divided by 120 volts = 3 amps)—well within the capacity of your 15-amp system.

OK so based on that you should not have more than 8 devices on a 15 amp circuit, and not more than 12 on a 20 amp circuit.

Where does the breaker trip on a circuit breaker?

There is a diagonal hatched area that is where the breaker may or may not trip. To the left of the diagonal area, the breaker must pass current; to the right of the hatch area the breaker must trip. This accounts for tolerances in the trip point.
