Step by step
Have a licensed electrician assess your panel's available breaker space.
The surge protective device (SPD) is installed at the main panel or subpanel.
It's wired to two breaker slots and grounded to the panel bus.
Ask about a status indicator light so you know when it needs replacing.
Pair with point-of-use surge strips for sensitive electronics.
Questions to ask your pro
- Are you a licensed electrician, and do you carry liability insurance?
- What brand and model surge protector do you recommend, and what is its joule rating and clamping voltage?
- Does my panel have sufficient breaker space, or will additional panel work be needed?
- Will this job require a permit, and will you pull and close it?
- Does the unit have a status indicator light so I know when it needs replacing?
- Will this protect my HVAC system and large appliances, or do I need supplemental point-of-use protection?
- What is the warranty on the device, and does your labor come with a guarantee?
