Virginia Lightning by the Numbers
Vaisala Xweather’s 2025 annual lightning report counted 3,143,967 lightning events in Virginia, out of about 252 million across the continental United States. Vaisala said U.S. lightning activity reached an eight-year high in 2025, up 20% from 2024. Those counts include both cloud-to-cloud and cloud-to-ground lightning, so they measure how active storms were, and not every flash reaches the ground.
A panel surge device limits surges that arrive on the service. On a spread-out property, though, some of the equipment most exposed to a strike close to the property sits at the far end of long wires: a well pump, a detached shop, an irrigation controller, or a gate operator. The sections below cover those.
04 — Shops
Shops and Barns Fed From the House
A detached shop or barn with its own panel sits at the end of a feeder from the house, and the electrical code treats that building separately for grounding. Under the National Electrical Code, a separate building supplied by a feeder must have its own grounding electrode system, and the feeder generally must include an equipment grounding conductor.
That matters for surge protection because a surge device works by diverting surge current into the grounding system. NEMA’s Surge Protection Institute defines a Type 2 device as one installed on the load side of the service equipment, including devices at a branch panel, so a shop panel can carry its own.
For a shop running a compressor, a welder, or a chest freezer from its own panel, we look at a Type 2 device at that panel in addition to the one at the house, after checking that the building’s grounding is in place. Virginia’s code requirement applies at the service, so a device at the shop panel is our recommendation for that equipment.
05 — Well Pumps
Well Pumps and the Wire Down the Well
A submersible well pump motor sits at the bottom of a long cable, and pump makers sell surge arrestors to protect these motors. Franklin Electric calls its arrestors highly recommended for protecting submersible motors from common high voltage spikes that can damage motor insulation and cause winding failure, and it offers a lightning surge arrestor for its SubDrive pump drives as well.
Our part is the electrical supply: a hardwired surge protector on the pump’s circuit or at its disconnect, in addition to the panel device. Which arrestor belongs inside a pump control box or drive is a question for your well contractor and the pump’s manual. Protection like this helps limit damage and cannot make a pump lightning-proof.
06 — Controllers
Irrigation Controllers, Gate Openers, and Other Long Runs
An irrigation controller can take a surge from two directions: its power supply, and the field wires running out to valves across the yard. Rain Bird’s grounding guide says surge devices must be connected to a suitable ground electrode to be effective, since they are designed to send surge energy to ground before it travels through the protected equipment, and that a lower-resistance ground dissipates a surge better.
The same guide is candid that no system can be protected against lightning damage 100% of the time. It is written for large golf course systems, so the principle carries over better than its specifications.
For a home, we can protect the circuit feeding an outdoor controller or gate operator, alongside the panel device. Protection on the controller’s own field wiring is for the irrigation or gate installer and the equipment manufacturer to specify.

08 — Process
How a Suffolk Surge Protection Visit Works
Check for an existing device
We look for a surge device at the panel, read its indicator, and check its breaker.
Written estimate
If a device is needed, you get a free written installation estimate before any work.
Install and confirm
A Type 2 device goes on its own breaker, and we show you what its indicator should read.
Review the other protection
We point out equipment that would benefit from hardwired or plug-in protectors.
