A breaker that trips is doing its job. The question is which of four things it is protecting you from: an overload, a short circuit, a ground fault, or a failing breaker itself.
Overloads are the most common and the easiest to spot — the trip happens when you add a specific appliance. Ground faults tend to appear with moisture, especially in bathrooms, garages, and exterior outlets after Bay Area winter rain.
The reaction to avoid is replacing the breaker with a larger one. That removes the protection without fixing the cause and lets the wire carry more current than it was sized for.
If a breaker trips more than once in a week, treat it as a diagnostic call rather than a reset.
