Why does my breaker keep tripping?

A breaker that trips repeatedly is doing its job — something on that circuit is overloading it or shorting. The usual suspects are a failing appliance, too many high-draw devices on one circuit, or a worn breaker. What you must not do is keep resetting it or swap in a bigger breaker: the breaker protects the wire, and upsizing it is how electrical fires start.

Likely causes

• Overloaded circuit — Space heaters, hair dryers, and microwaves on one circuit are the classic trio.
• Failing appliance — A motor going bad (fridge, AC, pump) draws surge current and trips the breaker as it dies.
• Short or ground fault — Trips instantly on reset, often with a pop or smell — wiring damage or a dead appliance.
• Worn breaker — Breakers do age out; one that trips under clearly light load may itself be the fault.

What you can check yourself

• Unplug everything on the circuit, reset once, then plug in one device at a time to find the culprit.
• Note the timing: instant trip = short; trips after minutes = overload or heat.
• Never upsize a breaker, and don't tape or wedge one on.

Typical cost

A troubleshooting visit in Los Angeles, CA typically runs $150–$350; breaker replacement $150–$300; a new dedicated circuit $400–$900.

When to call a pro

Burning smell, scorch marks, buzzing from the panel, or a breaker that trips instantly with nothing plugged in — call an electrician, not a handyman.
