Do You Need Surge Protection in Cary?

A surge is a short spike in voltage, well above the normal level your wiring is meant to carry. Some surges come from outside the house, from lightning nearby or from switching on the utility lines. Others start inside the house, when large motors like an air handler, a well pump or a refrigerator compressor cycle on and off. A big surge can ruin a circuit board in a second. Smaller surges can wear electronics down slowly over time.

A whole-house surge protective device is mounted at your main panel and covers every circuit in the house at once. When the voltage jumps, it sends the extra energy to ground before it can spread through your wiring. It protects things a plug-in strip can't reach, like the HVAC system, water heater controls, the range, the dishwasher and the thermostat on the wall. Those items are hardwired or tucked behind appliances, and they're often the most expensive to replace.

Adding a surge protector to your main panel is work on your home's service equipment. In North Carolina, that job belongs with a licensed electrical contractor. I'm Hugo Balbuena, owner of Electric All Pro, and our license number is NC L.32531. We serve homes all over Cary, including Preston, MacGregor Downs and Cary Park, as well as Raleigh, Wake Forest and Durham. The work is done inside a live panel, so experience matters for your safety and for the device to work.

Before you hire anyone, look them up. The NC Board of Examiners of Electrical Contractors lets you check a license online, and it only takes a minute. A licensed contractor can also pull the permit with the Town of Cary. That gives you an inspected, documented job instead of a device someone screwed onto the panel with no record. Here are some fair questions to ask anyone who quotes the work.

Yes, in most cases. In Cary, most electrical work beyond minor repairs needs a permit, and a surge protector wired into your main panel goes past a minor repair. Permits and inspections run through the Town of Cary Inspections & Permits office at Town Hall on N. Academy Street. The permit covers the work we do at your panel. The inspection gives you an independent check that the installation was done properly.

You don't have to go to Town Hall or fill out any forms. We pull the permit and schedule the inspection as part of the job. When the inspector comes, they look at the work at the panel. If anything needs attention, we take care of it. For you, that means one phone call to us instead of juggling the Town, the inspector and the contractor on your own.

I won't put a price on this page, because the honest answer depends on your house. Two homes on the same street in Cary can be very different jobs, depending on the panel, how old it is and what was done to it over the years. What I can do is explain what drives the price, so the quote makes sense when you get it and you can compare it fairly.

The biggest variable is usually the panel, not the surge device. If there's no open space for the breaker the device connects to, or the panel is old enough that parts are hard to find, the job changes. If the grounding at the panel isn't right, the surge protector has nowhere good to send the extra energy. That needs to be fixed first, or the device won't do its job.

Estimates for new installations are free. If you already know you want surge protection, call and tell me what kind of panel you have and roughly how old the house is. We can talk through what the visit will cover, what we'll look at and what could change the scope before anyone opens the panel.

Most of the work happens at your main panel. We start by looking over the panel and the grounding, because a surge device is only as good as its path to ground. Then we mount the device as close to the panel as possible and keep the wires short and direct. Short leads help the device react quickly, which is why placement matters as much as the brand you choose.

The power to the house has to be off for part of the job, so plan around that. Afterwards, reset your clocks and check anything that runs on Wi-Fi. Before we leave, we show you the indicator lights on the device, so you know what normal looks like. Then the Town of Cary inspection is scheduled, and we'll tell you what to expect when the inspector visits.

A whole-house device handles the big surges at the panel. It still lets a small amount of leftover voltage through. For computers, TVs and home office equipment, a good plug-in surge strip at the outlet adds a second layer. The two work together. A strip can't protect your HVAC or your range, and the panel device on its own isn't the whole answer for sensitive electronics.

Surges can also come in on cable TV, internet and phone lines. If a storm takes out a modem or router, that line may be how the surge got in, so ask about protecting those lines too. Surge protectors also wear out. Each surge they absorb uses up some of their capacity. Check the indicator light now and then, especially after a bad summer storm in Cary.
