What to Do After Your Home Experiences a Major Power Surge

Jun 30, 2026

A major power surge can send a sudden spike in voltage through your home’s electrical system, potentially damaging wiring and connected electronics. Although small surges of electricity occur daily, the major ones pose a risk to your electrical equipment and wiring. Taking fast action during the first few minutes is important.

Is It Safe to Stay Inside After a Power Surge?

Generally, it’s safe to stay indoors after a power surge, but some hazards aren’t so easily identified. Large power surges can damage internal wiring systems or overheat circuits. If you smell burning, have flickering lights, or see burnt outlets, get out of the house and call an electrician.

Step 1: Unplug Your Devices Right Away

All the electronic devices and appliances should be unplugged from their outlets since there may still be fluctuations in the voltage levels.

Computers, televisions, refrigerators, and HVAC units are particularly vulnerable. A secondary voltage spike, which often follows the first, can destroy what the initial one did not.

Pull plugs by the body, not the cord, to avoid damaging the outlet. Do not reconnect anything until a professional confirms the system is stable. Ask your electrician about Whole House Surge Protector Installation as a long term safeguard for your home.

Step 2: Reset Your Circuit Breaker

Check your home’s electrical box to see whether any breakers have been tripped after the power surge.

Look for breakers stuck in the middle position, not fully on or off. Switch them fully to “off,” then back to “on” to reset. If a breaker trips again right away or will not reset, stop. Forcing it repeatedly is not safe. This indicates a wiring problem underneath that requires professional repair.

Step 3: Check Your Appliances for Damage

Once the power is restored, test each appliance individually for:

  • Burning smells or scorch marks near plugs
  • Devices that won’t turn on
  • Buzzing or crackling sounds from walls or equipment
  • Error codes on smart systems or HVAC units

Some appliances may appear fine but still carry internal faults. Refrigerator motors and AC units take the worst hit from voltage spikes. When in doubt, have a licensed electrician take a look before a small problem turns expensive.

Step 4: Call a Licensed Electrician

Even if nothing seems wrong, a professional inspection is non-negotiable after a significant electrical event. An electrical professional should inspect your home after any major power surge.

Surges can overheat wiring inside your walls, causing damage that is invisible to the eye but can become a serious fire risk days or weeks later.

A professional will test outlets, inspect the panel, check the grounding system, and confirm wiring is safe. What looks like a minor inconvenience could be a serious electrical hazard.
