Whole-Home Surge Protector Installation in Charlotte, NC

Our Charlotte team (Matthews branch) completed a whole-house surge protection upgrade for homeowner Laura Harosky in Charlotte, NC. Led by technician Danny Bishop, this project centered on installing a premium surge protective device at the main electrical panel to shield the home’s electrical system and connected equipment from damaging voltage spikes. Completed on December 15, 2025, the installation included permitting and code-compliant workmanship from our Panels & Service Upgrades and Whole-House Surge Protection specialists.

What we installed

Main panel surge protector: Mounted at the primary electrical service panel to divert excess voltage safely to ground before it can impact branch circuits, appliances, and electronics.
Electrical permit: We filed the required electrical permit with the county for a fully documented installation.
Supporting electrical work (same visit): Per the customer’s scope, we provided a dedicated 50-amp, 240V circuit using 6/3 NM‑B wiring, PVC conduit as applicable, a 50A breaker, and a standard receptacle for a customer-supplied major appliance.

This surge protection upgrade helps reduce risk from lightning-induced surges, utility grid fluctuations, and internal cycling of large appliances, while supporting the home’s power needs with a robust new circuit.

How whole-house surge protection protects your home

Installed at the main service panel, the surge protective device intercepts transient overvoltage events and redirects excess energy to ground. By stopping destructive spikes before they reach sensitive circuitry, it helps:

Protect refrigerators, HVAC equipment, ranges, dishwashers, and other hard‑wired appliances
Safeguard electronics connected across multiple circuits
Extend the lifespan of devices by reducing cumulative surge-related wear
Improve overall resiliency of your electrical system
