Whole-House Surge Protection in Potomac Mills, VA

Prince William County says the 2021 code requires a surge protective device on any new dwelling service, so a Potomac Mills panel upgrade now comes with one. For an older panel, adding a surge device is a smart step after storms like the February 16, 2025 wind event, which knocked out power for more than 10,000 Dominion and NOVEC customers in the county.

What storms have hit Potomac Mills power lines?

Wind is the usual trouble here. On February 16, 2025, a High Wind Warning brought gusts of 50 to 60 mph. That Sunday evening, Dominion reported 7,496 outages in Prince William County and NOVEC reported 3,322, per Potomac Local.

On May 26, 2021, storms roared across the region and a buoy on the Occoquan River, just north of Potomac Mills, clocked an 82 mph gust. Dominion counted more than 400 customers out in the Woodbridge area, and NOVEC had nearly 650 out in the county (Potomac Local).

When lines go down and come back, the voltage on your wires can jump. A surge device at the panel is the first line of defense for the whole house. Plug-in strips still help at the TV and computer.

Do new and old Potomac Mills panels need a surge device?

For new services, yes. The county's 2021 code change page says services supplying dwelling units must have a surge protective device. If we upgrade your panel or service, the device is part of the job.

Most panels here are older than that rule. The median home was built in 1988, and only about 13% of homes went up after 1999 (Census ACS). Those panels went in long before the rule, so many have no surge device, and adding one is a retrofit.

Is a permit needed for the retrofit? We could not confirm it. The USBC exempt list does not name surge devices, and we found no county page that answers it. Call Building Development at 703-792-6930 to confirm before the job.

Report the outage to the right company

Potomac Mills has two power companies. Most homes are Dominion Energy, and the shopping area around the mall is NOVEC, per the federal territory map. The county's power outage page lists Dominion at 1-866-366-4357 and NOVEC at 703-335-0500, and it says never to assume a neighbor has reported it.

If only part of your house lost power, or lights flicker after the storm, the problem may be in your panel. That is a job for electrical troubleshooting, not the utility.

Whole-House Surge Protection questions in Potomac Mills

What Potomac Mills homeowners ask about whole-house surge protection.

Is a whole-house surge protector required in Potomac Mills?

For a new dwelling service, yes. Prince William County says the 2021 code requires a surge protective device on services supplying dwelling units. An older panel that is not being replaced does not have to add one, but it is a good upgrade.

Do I need a permit to add a surge protector to my panel in Prince William County?

We could not confirm it. Surge devices are not on the state's list of exempt work, and no county page answers it. Call Building Development at 703-792-6930 before the work.

Who do I call when the power goes out in Potomac Mills?

The company on your bill. Most homes are Dominion Energy, at 1-866-366-4357. Homes and shops in the NOVEC area near the mall call 703-335-0500.

Does a surge protector help after storms like the February 2025 winds?

It helps with the voltage spikes that can come when lines drop and power returns. It cannot stop a direct lightning strike. Use plug-in strips at key electronics too.
