Whole-Home Surge Protection in Santa Clara, CA
One surge — from the grid, a nearby strike, or your own big motors — can wipe out your electronics, EV charger, heat pump and smart panel. A whole-home surge protective device (SPD) at the panel is now NEC 230.67 code on service upgrades, and cheap insurance for an electrified home.

surge protection in Santa Clara: FAQ
Do I really need whole-home surge protection in Santa Clara?+
If you've added — or plan to add — an EV charger, heat pump, solar, or a smart panel, yes. Those are exactly the loads a surge destroys, and NEC 230.67 now requires an SPD on new and upgraded services. It's a small add that protects thousands in equipment.
Isn't a power strip enough?+
No. A plug-in strip only protects what's plugged into it, and not from the biggest surges coming in on your service. A panel-mounted SPD clamps the surge at the source, protecting your whole home — hardwired loads included. We often layer both.
