Whole-Home Surge Protection · Florida
A whole-home surge protective device (SPD) mounts at the panel and limits voltage spikes before they reach your circuits. The current National Electrical Code requires one for new and replaced services in dwellings; it works best paired with plug-in protectors for electronics.
Florida has some of the highest lightning activity in the country, and hurricane season makes surge protection and generators routine.
Across the Southeast, homes deal with heat, humidity, frequent thunderstorms and hurricane season near the coast. Permit offices, utilities and housing stock differ by city, which affects how whole-home surge protection is planned and scheduled. These local guides cover the Florida cities where we have written specific notes.
