01
Why Does a Breaker Keep Tripping?

A circuit breaker keeps tripping because it's doing exactly what it was built to do — cutting power to protect your home from excess current or a fault condition.
The three root causes are overload, short circuit, and ground fault. An overload happens when the total wattage of connected devices exceeds what the circuit is rated for, typically 15 or 20 amps on a standard branch circuit. A short circuit occurs when a hot wire touches a neutral wire, sending a sudden current surge that trips the breaker immediately. A ground fault is similar but involves current reaching a grounded surface or a person. A breaker that keeps tripping under any of these conditions is signaling a problem that needs to be found, not repeatedly reset.

Which Breaker Tripped? How to Find It in Your Panel

Open your main electrical panel and scan each breaker's switch position — a tripped breaker typically rests in the middle rather than sitting cleanly at ON or OFF.
Many panels include a panel schedule on the inside door that maps each breaker number to a room or circuit; if yours is missing or illegible, an electrician can relabel it during a service visit. Some breakers also show a small red or orange indicator window when tripped. To reset, push the switch firmly all the way to OFF first, then back to ON — skipping that intermediate OFF step is a common mistake that leaves the breaker half-reset. If no single switch looks different, check for a tripped GFCI outlet in a bathroom or kitchen, since those can cut power to entire circuits.

Water Heater, Furnace, and Heat Pump Breakers That Keep Tripping

A water heater tripping its breaker is one of the most common service calls we see in Yakima, and it almost always comes down to a failing heating element drawing more current than the dedicated circuit can handle.
Electric water heaters typically pull 3,500 to 5,500 watts; a new hot water heater that keeps tripping the breaker right after installation usually signals a wiring or breaker sizing mismatch. Furnace breaker trips follow a similar pattern — when the blower motor or heating element starts to fail, it draws excess current and the breaker responds. A heat pump keeps tripping its breaker for related reasons: the compressor pulls high start-up current, and on an aging or undersized circuit, that surge is enough to trip a 30- to 60-amp double-pole breaker repeatedly. Each of these appliances requires its own dedicated circuit by code.
04
Breaker Trips Immediately After Reset — What That Means

When a breaker keeps tripping immediately after reset — within seconds of being switched back on — the cause is almost never an overload.
Overloads require time to build up heat; a breaker that trips immediately points to an active short circuit or damaged wiring still carrying current. Unplug everything on the circuit, reset the breaker once, and if it holds with no load connected, start adding appliances back one at a time. If the breaker trips even with nothing plugged in, the fault is inside the wall wiring or at an outlet, junction box, or fixture. In Yakima's older homes, aluminum branch-circuit wiring from the 1960s and 70s is prone to loosening at connection points, creating exactly this kind of intermittent short circuit — a condition that requires a licensed electrician to remediate safely.
05
GFCI, Refrigerator, and Well Pump Breaker Trips

A GFCI outlet keeps tripping when it detects even a small current imbalance — as little as 5 milliamps — between the hot and neutral legs, which is enough to indicate a potentially dangerous ground fault.
Before calling an electrician, press the TEST button, then RESET; if it won't reset or trips again immediately, the outlet or the device plugged into it may be faulty. A refrigerator keeps tripping its breaker most often because of compressor start-up current spikes on a shared or aging circuit. If a well breaker keeps tripping, the well pump's motor may be drawing excess current due to a failing capacitor, a stuck pump, or a waterlogged pressure tank — any of these can pull two to three times the normal running amperage.
06
Whole-House Power Keeps Tripping

When the whole house loses power rather than one room, the main breaker has tripped — and that's a different situation than a circuit tripped at a single breaker.
A main breaker handles 100 to 200 amps and trips when total panel load exceeds its rating or when there's a fault at the service entrance. If your electricity keeps tripping across the whole house during Yakima's peak summer cooling months, the panel may be overloaded from simultaneous AC, appliance, and EV charging demand. My breaker keeps tripping during storms can also mean a utility-side issue — contact Pacific Power first to rule that out. Homes with older overloaded panels or legacy Federal Pacific equipment are especially vulnerable. A circuit breaker keeps tripping in one room points to a branch circuit fault, not the main breaker, and is a much simpler repair.
