Immediate danger: get to safety
Downed wires or damaged service equipment
Keep people and animals away. Treat downed wires and anything they contact as energized. Call 911 for immediate danger, and report the electrical problem to the utility. Do not approach to photograph, move or identify a wire. Electrical Safety Foundation: home safety ↗
An outage without visible danger
Report the outage to your actual electric provider. Naperville Electric Utility lists (630) 420-6060 for outage reporting. This is the City’s number, not this website’s. City official contact directory ↗
If only your property or part of it is affected, explain that when reporting. The utility or a qualified electrician can help establish responsibility. Do not enter a flooded basement or approach wet electrical equipment.
A recurring fault without active smoke or fire
Stop using the affected equipment and arrange prompt professional evaluation. Describe trips, unusual brightness, buzzing, discoloration or heat when booking. Do not accept reassurance from an online symptom list that the condition is harmless.
For a provider, verify actual availability and whether they handle the work you need. This site has no emergency contractor network and makes no response-time promise. See how to choose an electrician.
While waiting for help
Keep people away from damaged equipment. Do not repeatedly reset protection or open a panel. Do not use improvised generator connections. If conditions worsen, leave and call emergency services.
Use generator safety guidance before considering temporary backup power. A portable generator must never run inside a home or garage.
