Power surges can strike without warning and cause serious damage to your home’s electrical system, appliances, and sensitive electronics. These unexpected voltage spikes can disrupt daily activities and lead to costly repairs if not addressed promptly. From fried electronics to tripped circuit breakers, a sudden spike in voltage is more than just an inconvenience, it’s a hazard.
Here we will explain what causes power surges, how to fix them, and most importantly, how to prevent them from happening again.
4 Most Common Causes of Power Surges
Several factors can lead to electrical surges in a residential home:
- Lightning strikes: A nearby lightning strike can send a massive surge through power lines, directly impacting your home.
- High-powered devices: Equipment like air conditioners, refrigerators, or washers can create internal spikes when switching on or off.
- Faulty wiring: Damaged or loose connections increase the risk of irregular voltage levels and surges.
- Power outages and grid switching: Sudden restoration of power after an outage can lead to voltage spikes that affect sensitive electronics.
5 Signs You’re Experiencing Power Surges
Look out for these indicators of electrical fluctuations and power spikes:
- Lights flicker or dim without explanation
- Devices turn off or reset randomly
- Electronics make a buzzing or popping sound
- Circuit breakers trip often
- Data loss on computers or digital equipment
7 Tips to Fix and Prevent Power Surges
Power surges aren’t always avoidable, but you can take protective measures to minimize the damage and reduce the chances of them happening in the future.
Here are some useful tips below:
1. Unplug Unused Devices
One of the easiest ways to protect sensitive appliances and electronics is by unplugging them during storms or when not in use. This removes them from the supply and eliminates the risk of excess voltage damaging internal components.
2. Use Surge Protectors
Surge protector power strips are your first line of defense. Make sure you buy certified protectors and replace them every few years.
- Use surge protectors for computers, TVs, and gaming consoles
- Never daisy-chain multiple power strips
- Choose models with indicator lights and sufficient joule ratings
3. Install a Whole-Home Surge Protector
A whole-house surge protector is installed at your electrical panel and safeguards your entire system. It’s an effective solution for homes with frequent storms, power outages, or high demand from multiple large appliances.
4. Check and Upgrade Your Wiring
In many older homes, outdated or undersized wiring can’t handle high demand and may cause both surges and sags. Have an electrician inspect your wiring and recommend any updates.
- Upgrade aluminum wiring to modern copper wiring
- Add dedicated circuits for large appliances
- Repair any exposed or damaged outlets and connections
5. Schedule an Electrical Inspection
If you experience recurring surges, don’t ignore the problem. A licensed electrician can identify hidden issues like loose connections or mismatched voltage levels.

6. Protect Your Home from Outdoor Hazards
External damage can lead to unexpected surges. Protect your electrical components by trimming trees near power lines, weather-sealing meter boxes, and keeping water away from your outlets and exterior systems.
7. Install Dedicated Circuits for Major Appliances
Large appliances should have their circuits to avoid stressing your electrical system. This improves voltage stability and reduces the risk of spikes.
- Reduces electrical load on shared circuits
- Helps maintain a steady voltage supply for sensitive electronics
Expert Advice for Homeowners
