Whole Home Surge Protector: How Breaker Panel Protection Works
Whole home surge protectors install directly in your electrical panel and intercept voltage spikes before they reach sensitive electronics. These surge protective devices (SPDs) handle surges up to 50,000 amps from lightning strikes or utility grid fluctuations. A quality whole-home SPD costs $300-$600 installed and protects all circuits simultaneously. Unlike power strips, panel-mounted units safeguard your entire electrical system including hardwired appliances.
