Partial outage guide
Part of the house lost power: should you call the utility or an electrician?
The practical answer
Request urgent electrical help for sparks, burning odors, unusual heat, water exposure, or damaged equipment. Use emergency services first for an active fire. Otherwise check the utility’s outage information from a safe location and note which rooms and major appliances are affected. If only the property is affected, breakers repeatedly trip, lights are unusually bright or dim, or there is heat, odor, buzzing, or damage, request prompt electrician and/or utility evaluation.
First identify unsafe conditions
Do not approach wet, damaged, smoking, hot, or arcing electrical equipment. Warn others, leave, and call emergency services when the situation is immediately unsafe.
If there is no active emergency, avoid opening the panel or removing covers. You can describe the rooms, lights, receptacles, and fixed equipment that stopped working without touching conductors.
Patterns that show why part of the house lost power
One dead receptacle may involve a GFCI or local problem. One dead circuit may involve a breaker or circuit fault. Several unrelated areas, major 240-volt equipment behaving abnormally, or lights becoming unusually bright and dim can involve service or utility conditions that deserve prompt attention.
Ask neighbors or check the utility outage map only if it is safe. A utility-wide outage does not rule out property damage after a storm, and a normal outage map does not prove the problem is inside the home.
- One device
- One room or circuit
- Several unrelated rooms
- Whole home
- Neighbors or street also affected
- Storm or visible service damage
Do not repeatedly reset a breaker
A breaker that trips again is not repaired by another reset. Stop using affected loads and request evaluation. Repeated attempts can keep a fault energized and erase useful information about what was operating when the trip occurred.
Information to provide on the call
Tell the utility or electrician when the outage began, whether neighbors are affected, which rooms and large appliances have power, whether lights changed brightness, and whether there is heat, odor, sound, moisture, or visible damage.
- Exact service address
- Outage start time
- Affected rooms and 240-volt equipment
- Weather and utility status
- Breaker behavior
- Recent electrical work or new loads
Which pattern points where
| Pattern | What it may involve | Next step on the page |
|---|---|---|
| One dead receptacle | A GFCI or a local problem | Describe what stopped working without touching conductors |
| One dead circuit | A breaker or a circuit fault | Do not reset repeatedly; request evaluation |
| Several unrelated rooms | Service or utility conditions | Prompt attention |
| Lights unusually bright and dim | Service or utility conditions | Prompt attention |
| Neighbors or the street also affected | A utility outage | Check the outage map only if it is safe |
| Sparks, burning odor, heat or water exposure | A hazard condition | Urgent electrical help; emergency services for active fire |
Questions
Common questions
What does it mean when half the house has power and half doesn't?+
A home's service is typically fed by two 120-volt legs, and losing one leg leaves part of the house dead while the rest works. A pattern that can come from a service or panel connection or from a utility-side condition. That specific symptom is worth reporting exactly as you see it, because it points diagnosis in a particular direction.
Should I call the utility first?+
Check the utility outage status when safe. If the property alone is affected or there are internal warning signs, an electrician may also be needed.
Can I remove the panel cover to check?+
No. Do not expose conductors or service equipment. Provide safe observations and let qualified personnel investigate.
Why did some lights get very bright or very dim during the outage?+
Lights brightening on some circuits while dimming on others, or 240-volt equipment behaving oddly, can indicate a lost or loose neutral, which is a condition to treat as urgent rather than wait out. Unplug sensitive electronics if you safely can and get it evaluated promptly.
Could a simple tripped breaker cause a partial outage?+
Yes: a single tripped breaker or a tripped GFCI can take out a group of outlets or a room, which is the easy end of the range. The harder end is a service or utility fault, so checking for an obvious trip first (without opening the panel) is a reasonable starting point.
How do I tell whether it's my problem or the power company's?+
Check whether neighbors are affected and whether the utility shows an outage for your address; a problem confined to your property, or internal warning signs like odor or heat, points toward your wiring rather than the grid. Report which it is when you call, because it changes who needs to respond.
What should I switch off during a partial outage?+
Turning off or unplugging sensitive electronics and large appliances protects them if voltage is unstable, and it reduces load when power is restored. Do this at the device or the wall, not by working in the panel, and leave the diagnosis to a qualified responder.
