A whole-home surge protector is installed at your main electrical panel — typically as a Type 2 SPD (surge protective device) that wires into a 240V breaker slot and clamps incoming voltage spikes before they reach branch circuits. Installation takes 1–2 hours, requires a brief power shutoff, and is licensed-electrician work.
Installation steps
- Shut off main power at the meter
- Mount SPD adjacent to or inside the main panel
- Connect to a dedicated 240V breaker slot
- Bond to neutral and ground
- Restore power and verify indicator LEDs
- Add point-of-use protection for sensitive electronics
