Your Power Strip Is Not Protecting Your Home
Most homeowners in Onalaska believe their surge-protected power strips are enough. They're not. Point-of-use strips absorb small surges at individual outlets — they do nothing for the 80% of surge events that enter a home through the main service entrance.
A whole house surge protector installs at your main electrical panel in Onalaska, WI and intercepts high-voltage spikes before they reach a single circuit in your home. One device. Complete upstream coverage.
