What to do if…
you experience repeated brief power surges and you’re worried about wiring or equipment damage

Short answer

Assume repeated surges can damage equipment and signal an electrical hazard: unplug sensitive electronics, reduce electrical load, and be ready to shut off power at the main breaker if you notice heat, smoke, sparking, or a burning smell.

Do not do these things

  • Don’t keep repeatedly resetting breakers or “forcing” a circuit to stay on.
  • Don’t remove the cover of the electrical panel or touch service conductors.
  • Don’t ignore burning/plastic smells, buzzing/crackling, warm outlets, scorch marks, or smoke.
  • Don’t keep using a surge protector/power strip if its protection/status light is off, it looks damaged, or it smells hot.
  • Don’t run multiple high-draw appliances (space heater, dryer, oven, A/C) while power is unstable.
  • Don’t assume it’s safe just because the lights come back quickly—brief surges can still be harmful.

What to do now

  1. Check for danger signs immediately. If you see smoke, sparks, a burning smell, crackling/buzzing at an outlet, warmth, or scorch marks, shut off power at the main breaker if it’s safe. If there’s a fire or you can’t safely cut power, leave and call 911.
  2. Unplug sensitive and high-value electronics. Unplug computers, TVs, consoles, modems/routers, chargers, and anything that keeps rebooting. This reduces the chance of damage from repeated spikes.
  3. Reduce demand while you figure it out. Turn off non-essential lights and avoid running high-power loads (A/C, space heaters, washer/dryer, microwave) until the issue is identified.
  4. Decide whether it’s your home or the neighborhood supply. If neighbors are flickering too (or streetlights are acting up), it points to a utility-side problem. If it’s only your home, it may be an internal wiring/connection issue.
  5. Contact the right party based on what you see.
    • If multiple homes are affected: call your electric utility and report repeated voltage fluctuations / flickering lights.
    • If there’s visible arcing at the meter/service drop, downed lines, or a burning smell outside: use the utility’s emergency/hazard line and call 911 if there’s any fire.
    • If it seems limited to your home or you saw warning signs inside: call a licensed electrician for a safety check.
  6. If a breaker tripped, don’t keep trying it. If you reset a breaker once and it trips again (or anything smells hot/burnt), leave it OFF, unplug what you can on that circuit, and wait for an electrician.
  7. If you hire someone, verify they’re properly licensed where you live. Many states have official license-check tools (often through a contractor licensing board or labor/licensing department). Use your state’s verification site before authorizing work.
  8. Make a quick log for the electrician/utility. Write down times, what was happening (lights dim/bright, devices rebooting), what big loads were on, and whether neighbors were affected. Take photos of any scorch marks or tripped breakers (without touching damaged equipment).
  9. If you rent, report it to the landlord/property manager right away (in writing). Ask for a licensed electrician and avoid temporary DIY fixes.

What can wait

  • You don’t need to decide right now whether to replace the breaker panel, rewire, or buy whole-house surge protection.
  • You don’t need to file an insurance claim unless you confirm actual damage and the surges have stopped.
  • You can wait to replace non-essential electronics until you know the power is stable again.

Important reassurance

Power surges and flickering can be caused by utility-side issues or by something as simple (but serious) as a loose connection in your home. Taking protective steps first—unplugging, reducing load, and getting the right professional involved—is the normal, sensible response.

Scope note

This is first steps only, focused on safety and preventing avoidable damage. Diagnosing and fixing the cause requires your utility and/or a licensed electrician.

Important note

This is general information, not electrical or fire-safety advice specific to your home. If you suspect an electrical fire risk (smell, heat, smoke, sparking), prioritize safety and emergency services.
