Learn about Electrical Panel UpgradesSurges can damage TVs, computers, and the circuit boards inside new appliances and furnaces. A whole house surge protector helps stop that.
How It Works
A whole house surge protector mounts at or next to your electrical panel. When a surge comes in, it sends the extra energy safely to ground.
Plug in surge strips still help for TVs and computers. Used together, they give two layers of protection.
What It Helps Protect
- Furnaces, heat pumps, and AC units
- Refrigerators, washers, and dryers
- TVs, computers, and home networks
- EV chargers and smart home devices
- Well pumps and sump pumps
Is It Required?
Newer editions of the National Electrical Code call for surge protection when a home's service is replaced or upgraded. Your county decides which code edition applies.
Even when not required, a surge protector is a low cost way to protect expensive equipment.
Installation
Most installs take an hour or two. The electrician turns off power, mounts the device, and connects it to the panel.
Many surge protectors have a light that shows they are working. Check it now and then, especially after a big storm.

Whole House Surge Protection Questions
Does it protect against a direct lightning strike?
No device can stop all damage from a direct strike. A surge protector greatly lowers the risk from most surges.
How long does a surge protector last?
It can wear down after big surges. If the status light goes out, have it replaced.
Do I still need power strips?
Yes, for sensitive electronics. They add a second layer of protection.
