What Is a Whole Home Surge Protector and Do I Need One?

Most people know about the power strips with surge protection they plug a computer into. A whole home surge protector does the same job on a much bigger scale, and it installs right at your electrical panel to protect everything in the house at once. Here is what it does and whether it makes sense for your home.

How it works

A whole home surge protector sits at your main panel and watches for sudden spikes in voltage. When a surge comes through, it diverts the excess energy safely to ground before it can reach your outlets. It reacts in a fraction of a second, faster than you could ever unplug anything.

Where surges come from

Surges are not just from lightning, though a summer storm can certainly cause one. Many surges come from the utility grid itself, from equipment cycling on and off, or from large appliances in your own home like an air conditioner, well pump, or refrigerator starting up. These smaller surges happen more often than people realize and can wear on electronics over time.

What it protects

Modern homes are full of sensitive electronics. Televisions, computers, gaming systems, smart appliances, furnace and air conditioner control boards, LED lighting, and EV chargers all have circuit boards that a surge can damage. A whole home protector guards all of them at once, which a handful of plug in strips cannot fully do.

Is it worth it

For most homes, a whole home surge protector is an affordable piece of insurance, especially given how much electronics cost to replace. It pairs well with plug in protection at your most valuable devices, since the two layers work together. If you are already having panel work done, it is a natural time to add one.
