Whole-Home Surge Protection · Iowa
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.
Derechos, tornadoes and cold winters make storm repair, generator hookups and sump-pump circuits common.
Across the Midwest, homes deal with cold winters, severe thunderstorms and tornado season. 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 Iowa cities where we have written specific notes.
