A breaker trips for one of three measurable reasons: the circuit is overloaded, a wire or device has a short, or a ground fault is leaking current. Repeated trips are the breaker doing its job — the fix is finding which of the three it is.
Overload is the common case: too many amps on one circuit, often a kitchen or space-heater circuit. The durable fix is a dedicated circuit for the heavy load, not a bigger breaker.
Shorts and ground faults are fault conditions, not capacity problems. They are located by isolating the circuit and testing segment by segment — never by resetting the breaker until it holds.
-
Map the trip
Note what was running when it tripped, and which outlets went dark.
-
Unplug and reset once
If it holds empty and trips under load, it is likely overload; if it trips instantly, suspect a fault.
