The power strip behind your TV protects one device from small surges. A whole-home surge protector, installed at your panel, defends everything in the house from the big ones — the surges that ride in from lightning, the utility grid, and large appliances cycling on and off. In a storm-prone area like the Pee Dee, it's one of the most cost-effective protections you can add.
What a power surge actually is
A surge is a brief spike in voltage. Small ones happen constantly — every time a motor like your AC or fridge switches off, it sends a little spike back into your wiring. Big ones come from lightning strikes (direct or nearby) and from grid events when the utility switches or restores power. Over time, the small surges wear out electronics; a big one can destroy them in an instant.
Layered protection: how it works
| Layer | Where it goes | What it stops |
|---|---|---|
| Whole-home (Type 2) | At or in the electrical panel | Large surges from lightning and the grid, before they spread through the house |
| Point-of-use (Type 3) | Plug strips at sensitive electronics | The smaller residual surges and spikes generated inside the home |
The two layers work together. The panel device takes the big hit; the plug strips clean up what's left for your most delicate gear. Relying on power strips alone leaves everything hardwired — HVAC, appliances, the EV charger, LED lighting — unprotected.
What it protects
- HVAC systems and heat pumps — expensive control boards are surge-sensitive
- Kitchen appliances with electronic controls
- LED lighting and dimmers
- EV chargers and their electronics
- Computers, TVs, and home networking gear
- Anything hardwired that a power strip can't reach
Florence and the surrounding counties see frequent thunderstorms and the occasional hurricane, and rural cooperative service adds grid-switching surges during outages and restoration. Homes here take more surge punishment than average — which is exactly why whole-home protection pays off locally.
Installation
A whole-home surge protector is installed at the panel by a licensed electrician — it's a quick job, often done alongside other panel work. It pairs naturally with a panel upgrade and is a smart companion to a standby generator, since grid switching during outages is a common surge source. To add protection, see our surge protection service or call (843) 595-9236.

Isn't a power strip enough?
No — a power strip only protects what's plugged into it and only against smaller surges. It leaves hardwired equipment like HVAC, appliances and EV chargers exposed. Whole-home protection covers everything.
Will a surge protector stop a direct lightning strike?
A direct strike is extreme and nothing guarantees full protection, but a quality whole-home device dramatically reduces damage from the far more common nearby strikes and grid surges.
Where is a whole-home surge protector installed?
At or in your electrical panel, by a licensed electrician. It's a quick install, often done alongside other panel work.
Do I still need power strips if I have whole-home protection?
Ideally yes — the best setup is layered: a panel device for the big surges plus point-of-use strips at sensitive electronics. Call (843) 595-9236 to set it up.
