Whole-Home Surge Protection · Ohio
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.
Older city neighborhoods in Cleveland, Columbus and Dayton carry aging wiring, and storms bring outages.
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 Ohio cities where we have written specific notes.
