Electrical Panel Upgrade Engineering in Key West, FL

The southernmost city in the continental U.S., Key West is an island chain city built on tourism, hospitality, and the military — home to Naval Air Station Key West, a dense Old Town historic district, and a cruise-ship port. Extreme hurricane exposure, corrosive salt air, and some of the lowest land elevations in Florida define every project.

What we engineer

Service load calculations per NEC Article 220 (220.82 for new loads, 220.83 for existing dwellings — Article 120 under the 2026 NEC); 100A-to-200A-to-400A service upgrades with Class 320 meter sockets; panelboard replacement and subpanel design per NEC Article 408; AFCI/GFCI updates per 210.12/210.8; whole-house surge protection per 230.67 and exterior emergency disconnects per 230.85; EV-ready panels with EVSE as a continuous load at 125% (625.41) and solar-ready panels with 705.12 busbar headroom.
