Why is there no power in half the house?
Answer
When half the house loses power, the issue is often a lost leg of service, failed main component, or major panel connection fault. If nearby homes still have power, your system needs targeted electrical diagnosis rather than repeated resets.
Why this happens
Typical causes include utility-side and customer-side failures.
- Main or feeder breaker issue affecting multiple branch circuits.
- Loose, damaged, or burnt connection at panel, meter, or service splice.
- Utility-side lost leg feeding the property.
Massachusetts context
In Massachusetts, service-mast and meter-adjacent repairs may require utility coordination before work can proceed. Safe restoration often depends on proper sequencing between utility and licensed electrician.
When to call an electrician
Call when only your property is affected, or when half-house power loss returns after reset attempts.
- Half the home remains out with no obvious tripped breaker.
- Main panel shows heat, buzzing, odor, or discoloration.
- Large appliances fail while smaller loads still operate.
