Durham Whole-Home Surge Protection

A power surge is a sudden spike in electrical voltage that can damage or destroy sensitive electronics and appliances. Surges can be caused by lightning, power outages, or large appliances cycling on and off. Without protection, even small surges can shorten the lifespan of your devices.

A surge protector blocks or redirects excess voltage away from your electronics during a power spike. It helps prevent damage to TVs, computers, appliances, and other plugged-in equipment. Surge protectors offer an added layer of defense beyond your home’s circuit breakers.

While they look similar, a power strip simply provides multiple outlets, whereas a surge protector includes built-in technology to stop voltage spikes. Not all power strips offer surge protection, so it’s important to check the labeling. Look for a joule rating to ensure it offers real protection.

Yes, whole-home surge protectors safeguard your entire electrical system from both internal and external surges. They’re especially useful in areas prone to storms or frequent utility fluctuations. Installed at your main panel, they protect everything from your HVAC to kitchen appliances.

Yes, surge protectors degrade with each power spike they absorb. Once their internal components wear out, they no longer offer protection—even if the outlet still works. It’s a good idea to replace them every few years or after a major surge event.

Many surge protectors have indicator lights that show whether protection is active. If the light is off—or if the unit was exposed to a large surge—it may no longer be effective. Replace any device that no longer shows a working status.

For the best protection, yes—whole-home surge protection handles large surges, while plug-in protectors shield sensitive electronics from smaller spikes. This layered approach offers comprehensive defense across your home. It’s especially important for expensive or irreplaceable electronics.

Whole-home units must be installed directly to your electrical panel and should only be handled by a licensed electrician. Improper installation can be dangerous and may void warranties or insurance coverage. Professional installation ensures safe and code-compliant protection.
