Whole-Home Surge Protection · Arkansas
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.
Spring storms and summer heat drive surge, storm-repair and AC-circuit calls; many rural homes rely on long service drops.
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. These local guides cover the Arkansas cities where we have written specific notes.
Central Arkansas storms bring frequent lightning, and spring storm seasons with tornado warnings are a regular part of life in Little Rock. Surges often damage HVAC control boards, appliances and electronics.
Utility: Entergy Arkansas
Northwest Arkansas sees frequent spring and summer thunderstorms, and lightning surges often damage heat pump boards, garage door openers and electronics in Fayetteville homes. Many residents work from home or study at the university, so computer and network equipment is common.

For example: Little Rock: Electrical permits in Little Rock come from the city's Planning and Development Department; North Little Rock and other cities issue their own. Fayetteville: Electrical permits inside city limits come from the City of Fayetteville's building safety division; Springdale, Rogers and Bentonville issue their own.
Little Rock: Entergy Arkansas. Fayetteville: SWEPCO (some areas: Ozarks Electric Cooperative).
