Partial power outage troubleshooting checklist
When only part of a property loses power, the cause may be a utility outage, damaged service, failed connection, tripped protective device, circuit problem, or equipment fault. Capture the pattern without opening electrical equipment so the right responder can act faster.
Unusually bright and dim lights, a burning odor, arcing, damaged service equipment, or shock can indicate a dangerous service or neutral problem. Keep people away and seek immediate help.
Make the condition safe
- Leave the property and call 911 for smoke, fire, active arcing, or a strong burning odor
- Stay away from downed conductors, damaged meters, leaning service equipment, and electrical equipment in standing water
- Turn off and unplug sensitive equipment only when it is safe to reach
- Do not remove a panel cover, meter seal, receptacle, switch, or fixture
- Do not repeatedly reset a breaker that trips again or will not remain on
Document exactly what lost power
- List the rooms, lights, outlets, appliances, HVAC equipment, pumps, gates, or business systems affected
- Note whether some 240-volt appliances behave differently or lights become unusually bright or dim
- Record when the outage began and whether it followed a storm, utility work, equipment startup, construction, or water intrusion
- Ask a nearby neighbor or tenant whether the same condition affects them without approaching utility equipment
- Photograph closed panels, visible breaker positions, damaged exterior equipment, and utility outage notices from a safe location
Prepare for utility or electrician response
- Check the utility outage map or report the outage when neighboring properties are also affected
- Tell the electrician if lights brighten and dim, half the property is out, or larger appliances are not operating normally
- Identify any breaker or GFCI that tripped, but leave it off if it trips again
- Share recent electrical work, equipment additions, water leaks, storm damage, or recurring symptoms
- Keep panel, meter, attic, crawlspace, and equipment access clear for qualified personnel
Questions for the diagnosis
- Is the failure on the utility side, service equipment, panel, feeder, branch circuit, connection, or connected equipment?
- Does the condition involve a lost service leg or neutral that requires immediate action?
- What temporary steps are safe until the permanent repair is completed?
- Will the repair require a permit, inspection, utility disconnect, or coordinated shutdown?
- What testing confirms that normal voltage and operation have been restored?
Do not let a partial outage become a larger failure
