Electrical Repair & Troubleshooting Guide for Homeowners

A circuit breaker trips when it detects more current than the circuit is rated to carry. This is a protection mechanism, not a malfunction — the breaker is doing its job. The question is what's causing the overload.

The most common cause is a simple overloaded circuit: too many appliances drawing power at once on the same circuit. High-draw devices like space heaters, hair dryers, microwaves, and vacuum cleaners are frequent culprits. The fix is distributing loads across different circuits or upgrading to a dedicated circuit for the heavy appliance.

If a breaker trips immediately when you reset it, or trips with nothing plugged in, that points to a short circuit or a ground fault — a more serious issue that requires a licensed electrician to diagnose safely.

Occasional light flickering when a major appliance kicks on — the air conditioner, dryer, or refrigerator compressor — is common in older homes and usually reflects the momentary voltage drop from a high-draw motor starting. It's worth noting but not immediately dangerous.

Persistent flickering, flickering that happens randomly with no appliance cycling, or flickering throughout multiple rooms is a more serious signal. It can indicate a loose connection at the panel, a deteriorating main service connection, or a failing neutral wire. These are not normal — and loose or arcing connections are a leading cause of electrical fires. Call a licensed electrician.

A burning smell from an outlet, switch, or panel is never normal and should never be ignored. Burning plastic or a hot, fishy smell often indicates arcing — electricity jumping a gap in a loose or failing connection, generating extreme heat. This is how electrical fires start inside walls.

If you smell burning near an outlet or switch: stop using that circuit immediately, do not plug anything in, and call a licensed electrician the same day. If the smell is coming from your panel or if you see scorch marks anywhere, call us immediately. Do not attempt to investigate inside the panel yourself.

GFCI (Ground Fault Circuit Interrupter) outlets are the ones with the TEST and RESET buttons, required by code in bathrooms, kitchens, garages, basements, and outdoor areas. They monitor the current flowing through the circuit and trip instantly if they detect even a small imbalance — the kind that would indicate current flowing through a person.

They trip for a reason: water, a failing appliance, or a fault in something plugged into the circuit. Before resetting a tripped GFCI, unplug everything on that circuit and try to identify what caused the trip. If it trips again immediately or repeatedly without anything plugged in, the GFCI itself may have failed and needs replacement — or there's a wiring issue downstream.

Two-prong outlets were standard before the 1960s. They lack a ground wire, which means electronics plugged into them aren't protected from surges the way they would be on a grounded circuit. Modern electronics and appliances assume a ground is present; running them from ungrounded outlets can shorten their lifespan and provides no fault protection.

The options are replacing with GFCI-protected outlets (which provide shock protection without a ground wire), running a ground wire to those outlets where the wiring allows, or in some cases, rewiring the circuit. A licensed electrician can evaluate your specific situation and recommend the safest, most cost-effective path.
