A power surge is a sudden spike in voltage that might damage appliances, electronics, and your home’s electrical system. Many people visualize lightning when they think of power surges, but most originate inside the house. Knowing the common causes of these events helps you avoid costly damage while maintaining a safer electrical environment for your household.
1. Lightning Strikes
Lightning is rare as a source of power surges, but it’s undoubtedly the most dramatic situation. If a bolt of lightning strikes close to a power line or even your residence directly, it might send thousands of volts through your home’s electrical system. In just a fraction of a second, it can damage outlets, destroy electronics, and even start a fire. Installing a whole-house surge protector in your home’s electrical panel is a good move. Also, unplug your most sensitive devices when severe weather rolls through.
2. Large Appliance Cycling
Every time one of your major appliances turns on or off, it can draw a significant amount of power. This can be your air conditioning, washing machine, or refrigerator. This sudden demand might trigger minor but, over time, repeated power surges that cumulatively wear down other connected electronics. Plug TVs, computers, and other sensitive devices into certified surge protector power strips. Large appliances might need dedicated circuits.
3. Faulty or Aging Wiring
Damaged or outdated wiring can’t always manage modern electrical loads. Corroded or frayed wires, worn-out insulation, and loose connections can all cause internal surges or inconsistent voltage delivery. If you notice flickering lights or your home is over 30 years old, schedule an electrician to inspect your wiring and potentially upgrade it.
4. Downed Power Lines or Grid Switching
Surges can happen outside your home. A tree might fall on a nearby power line, and the utility company may restore power following an outage or switch to an alternative power source. Any of these events can cause an unexpected voltage surge in your home.
5. Poorly Installed Electrical Devices
Improperly installed or inexpensive electrical devices, particularly those installed by DIY enthusiasts, can disrupt the electrical flow and create surges throughout your home. Always hire a licensed electrician for your home’s electrical work; avoid using uncertified or knockoff components.
Knowledge Is Power
Power surges result in too much power moving through your home. Recognizing these common causes allows you to take preventive steps that protect your property, electronics, and appliances. You can ensure your home’s electrical system continues to run efficiently and safely.
