Lost Power to Half Your House? What Newnan Homeowners Should Do Next

One side of the house is dark. The kitchen works, but the bedrooms are dead. Or half the lights and outlets went out while the other half still has power. That pattern is common in Newnan homes, and it usually points to a specific kind of panel or circuit problem rather than a whole-house outage. Here is what to check, what not to do, and when to call a licensed electrician. If you lost power to half your house, here is what is usually going on and what to do next.

Why Only Half the House Loses Power

Most homes get 240-volt service made of two 120-volt “legs” or hot legs. Lights, outlets, and small appliances run on one leg or the other. Larger loads like a range, dryer, or heat pump use both. If one leg drops out, roughly half your 120-volt circuits can go dark while the other half stays on. That is why the failure often looks random by room until you map which circuits share the dead leg.

A full utility outage usually takes everything. A single tripped branch breaker usually takes one room or one circuit. Half-house power loss sits in between, and it deserves a careful look at the panel and the main connections.

Common Causes We See in Coweta County Homes

• A tripped double-pole or main breaker: the main can partially trip, or a 240-volt double-pole breaker can leave one pole open so one leg is dead.
• A loose or failed connection at the panel: a weak lug on the main breaker, a bus bar problem, or a poor connection on a feeder can knock out one hot leg.
• Utility-side problems: a damaged service drop, meter base issue, or problem on the utility’s side of the meter can also drop one leg. Sometimes the fix is with the power company; sometimes it starts at your equipment.
• Overloaded or aging panels: panels that are undersized, corroded, or past their useful life are more likely to develop connection problems. That is a common reason homeowners look into an electrical panel upgrade in Newnan, GA.
• Storm damage or water intrusion: moisture in the panel, meter, or outdoor disconnect can cause intermittent one-leg failures after heavy rain.

Safe Checks You Can Do Before Calling

You can gather useful information without opening the panel:

• Confirm neighbors still have full power, so you know it is not a wide utility outage.
• Note which rooms, outlets, and lights are dead versus working. Write it down if you can.
• Check whether 240-volt appliances (range, dryer, heat pump outdoor unit) also stopped or are acting strange.
• Look at the main breaker and any double-pole breakers for a breaker that is not fully ON. Some trip to a middle position and need a firm OFF, then ON reset.
• Smell for burning or hot plastic near the panel, and listen for buzzing. If you smell burning at the panel, shut the main off if you can do so safely and call for help. See our guide on a burning smell from an electrical panel in Newnan, GA.

Do not remove the panel cover, tighten lugs, or probe live parts yourself. Those connections can carry lethal voltage, and a loose main lug can arc when disturbed.

When It Is One Room vs. Half the House

If only one room or a few outlets are out, start with a tripped branch breaker or a GFCI that protected a chain of outlets. Our pages on power out in one room in Newnan, GA and a breaker that keeps tripping in Newnan, GA cover that pattern. Half-house loss is different: many unrelated circuits die at once while others stay live. That pattern usually means a leg, main, or service issue, not a single room circuit.

How a Licensed Electrician Diagnoses It

When Shocking Electric Solutions, Inc. responds to half-house power loss, we start with voltage checks at the meter and panel to see whether both hot legs are present and balanced. From there we inspect the main breaker, lugs, bus, and feeder connections, and we determine whether the problem is on the homeowner side or needs the utility. If the panel itself is the weak point, we explain repair versus replacement options clearly before any work begins.
