This security is particularly valuable for homeowners with high-end appliances and electronics.
How Does Whole-Home Surge Protection Work?
Whole-home surge protection devices are installed at the main electrical panel, where they act as the first line of defense against surges. When a surge occurs, the surge protector detects the increased voltage and diverts excess electricity away from your home’s wiring and into the ground. This process ensures that only safe voltage levels reach your home’s circuits, preserving the integrity of connected devices.
Components of a Surge Protection System
- Primary Surge Protector: Installed at the main electrical panel, this device intercepts surges as they enter your home.
- Secondary Surge Protectors: Additional protectors installed at individual outlets can provide further protection for especially sensitive or valuable devices.
- Grounding System: A proper grounding system is crucial for whole-home surge protection, as it provides a safe pathway for excess electricity to be redirected.
