Breakers trip for three reasons, and the reason is the repair. Overload: the circuit is asked for more than its rating, classically a space heater and a hair dryer discovering each other; the fix is load management or a new circuit, not a bigger breaker, because the wire in the wall is the rating that matters. Fault: a short or a ground leak, reported by instant tripping. Wear: the breaker itself, which confesses by tripping under light load or feeling warm.
In Monterey, read a tripping breaker alongside the fog. Corroded connections at the panel or the device heat under ordinary loads and trip protection that is doing its job correctly. The safe sequence stands, unplug, reset once, observe, but a breaker that trips with a warm face or a buzz in this town is a corrosion inspection waiting to be scheduled, and resetting it weekly is how a finding becomes a fire report.
The safe home tests are few and they end early: unplug everything on the circuit, reset, and add loads back one at a time. If it trips empty, stop testing; the fault is in the wiring or the breaker, and both are a technician's meter work. Note which appliances were running at the trip; that list is half the diagnosis and the technician will ask for it.
What never to do: hold a breaker on, tape it, or swap in a larger breaker to stop the nuisance. The tripping is the protection working. Every electrical fire investigation that starts with a defeated breaker ends the same way, and the breaker was the cheapest part of the house it was protecting.
