Whole-Home Surge Protection in Mountain House, 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.

Permits & your utility in Mountain House
In Mountain House, electric service is Modesto Irrigation District (MID), and building permits are issued by San Joaquin County. We pull the permit on every surge protection, coordinate the service and meter to MID's MID Electric Service Guides — Residential Service Guide (of 8 guides), and pass inspection — so it's safe, legal, and protects your home's value.
Mountain House note: PG&E provides only GAS here; electric = MID since 2001. Not obvious for a San Joaquin new-growth area.

surge protection in Mountain House — FAQ
Do I really need whole-home surge protection in Mountain House?+
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.
