How Surge Protectors Work in Wake Forest

Your panel feeds every circuit in the house. A Type 2 surge protector connects right there on its own breaker and watches the voltage. When a spike comes in, it sends the extra energy to ground instead of letting it run down the wires to your refrigerator, your furnace control board, your router and your TV. When the voltage is normal, it just sits in the panel and you never notice it.

Spikes don't only come from lightning. Switching on the utility side, the moment power comes back after an outage, and big motors inside your own home starting and stopping all push surges through the wiring. A nearby strike gets everyone's attention, but the smaller everyday surges matter too, because they wear down the circuit boards in modern appliances a little at a time.

Here's what it can't do. No device makes a home safe from a direct lightning strike, and a surge protector doesn't fix a poor ground or a panel that's failing. It needs a sound panel to do its job. If I open your panel and see a problem, I'll show you and explain it before I install anything.

A plug-in surge strip only protects what's plugged into it. That leaves out everything that's hardwired: the heat pump or AC, the electric range, the water heater controls, the garage door opener, the smart thermostat and the doorbell. Most of those have circuit boards now, and they're often the most expensive things to repair. A protector at the panel covers every circuit, hardwired or not.

The best setup is both. The panel device takes the bulk of a surge where it enters the house, and a good strip at the TV and the computer handles what's left right at the outlet. Keep in mind that strips wear out. When the protection light on a strip goes dark, it's still passing power but it isn't protecting anything anymore.

With us, a whole-house surge protector runs $450–$1,000. That price covers the Type 2 device, the breaker it connects to, the installation and the testing afterward. The estimate is free. I come out, look at your panel and give you a price in writing before any work starts.

Where your job lands in that range depends on your panel. If there's an open space for the breaker and the panel is in good shape, the job is simpler. An older or crowded panel, a hard-to-reach location or a particular device you want all move the number. I'll tell you which of those apply to your home and why.

If surge protection is part of a bigger project, financing is offered on estimates over $1,000, with a soft credit check and no home equity. The $89 diagnostic is something different. That's only for finding the cause of a problem, for example when something stopped working after a storm, and it's typically credited toward the repair you approve.

A surge protector goes inside your panel, so it isn't a minor repair. In Wake Forest, most electrical work beyond minor repairs needs a permit. The town runs its own Inspections Department at Town Hall on S. Brooks Street. We pull the permit and schedule the inspection as part of the job, so that's one less thing on your list.

On the day of the install, the power has to be off while we work in the panel, so plan for the house to be dark for part of the visit. Before I leave, I test the device, show you the indicator light and explain what it should look like when everything is working. Then the inspector signs off.

For most homes, the question is how much you'd lose if one bad surge took out the HVAC control board, the refrigerator and the home office at the same time. Compared with replacing even one of those, a device that protects the whole house is a reasonable trade. It makes the most sense for people with a lot of electronics, a newer heat pump or a house full of smart devices.

I install these all over Wake Forest, from older homes downtown to newer houses in Heritage and Holding Village. If you're already planning panel work, add the surge protector at the same time. The panel will already be open and permitted, which keeps things simple.
