Whole-Home Surge Protection

One device, mounted at your panel, protects every appliance and electronic in your house. Install it once, replace it after a major event, and protect tens of thousands of dollars of equipment.

Power surges destroy equipment. Lightning strikes (even nearby — not direct), utility switching events, generator transitions, and large motor cycling all push voltage spikes into your home wiring. Plug-strip surge protectors help with one outlet, but they leave 90% of your home unprotected — your HVAC, your appliances, your hardwired electronics, your smart home devices, your solar inverter, your generator transfer switch.

A whole-home surge protector (technically a Surge Protective Device, or SPD) mounts in or beside your electrical panel and clamps voltage spikes before they reach your circuits. One device protects everything. Modern Type 1 and Type 2 SPDs handle massive surge events, have visual indicators showing when they have been used up, and are inexpensive to replace after a major event.

ABC Electric installs SPDs from the major brands — Eaton, Siemens, Square D, Intermatic, Leviton — sized appropriately for your service. Install is typically under two hours. We can also install secondary SPDs at sub-panels and at sensitive equipment circuits (whole-home audio, server closets, generator transfer switches) for extra protection where it matters.

Frequently Asked

Common questions about whole-home surge protection.

Do I still need plug-strip surge protectors?

Yes — for sensitive electronics (computers, TVs, AV equipment). Whole-home SPD handles the big surges; plug strips handle the smaller residual spikes. Layered protection is the right approach.

How long does an SPD last?

Depends on surge events. They have a finite capacity and are 'used up' over time by absorbing surges. The status indicator tells you when to replace. Most last 5-10+ years in normal conditions.

Will it protect against direct lightning?

Direct strike — nothing protects against that completely; the goal is damage minimization. Most surge events are not direct strikes — they are nearby strikes, utility switching, or motor cycling. SPDs handle all of those.

How much does it cost?

Whole-home SPD installation is significantly cheaper than replacing a single appliance after a surge event. We give you a flat-fee quote upfront.
