Whole-Home Surge Protection · Oklahoma
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.
Tornadoes, ice storms and summer heat make storm repair, surge protection and generators common.
Across the South Central, homes deal with long, hot summers, severe storms and occasional hard freezes. Permit offices, utilities and housing stock differ by city, which affects how whole-home surge protection is planned and scheduled.
