Recently the power went out in my detached garage. The breaker continues to trip after being on for a while. I have check all the wires and outlets on the circuit and they seem to be fine. I have even changed out the light switches and the outlets. What would cause the breaker to continue to trip?

May have something that comes on that overloads the circuit.

Or if breaker is old, spring may have gotten weaker from operating close to max.

If you have or know someone that has a current meter (or Amprobe) measure the current draw on this circuit to see if this is the problem. There may be an overload problem that you can't easily see that may be a hazard if not corrected...
