Whole-Home Surge Protection in Onalaska, WI
Lightning strikes in La Crosse County are becoming more frequent and more destructive every season. Sparks Electrical Solutions provides whole-home surge protection services to Onalaska homeowners, farmers, and businesses — NFPA 780-compliant installation, post-strike inspections, and emergency repair. Same-week appointments most of the year.
Whole-Home Surge Protection in Onalaska
Sparks Electrical Solutions installs Type 1 service-entrance surge protective devices (SPDs) on the line side of your meter, Type 2 SPDs at your main panel, and point-of-use Type 3 devices where they're needed. Together, these layers reduce a 6,000-volt transient down to something your appliances and electronics can shrug off.
Whole-home SPDs are now required by NEC 230.67 for all new and replacement service equipment serving dwelling units — but most older homes don't have them. If your panel is more than 5 years old, it almost certainly doesn't.

Frequently Asked Questions
Is a power strip the same as whole-home surge protection?
No. A power strip is a Type 3 point-of-use device, rated for very small surges. Whole-home protection (Type 1 or Type 2) stops massive surges at the panel before they ever reach your wall outlets. You want both.
How long does whole-home surge protection last?
Most quality SPDs have an indicator light that turns from green to red when they're spent. A typical unit will absorb hundreds of small surges and 1–2 major ones before needing replacement — usually 10+ years of useful life.
Will it protect my electronics from a direct lightning strike?
Whole-home surge protection is rated for transient overvoltages, not the full 100-million-volt energy of a direct strike. For that you need a full NFPA 780 lightning protection system (rods + ground).
