Whole-House Surge Protectors Explained
Understand what panel-mounted surge protection can and cannot do for appliances and sensitive electronics.
Understand the job
A surge protective device diverts transient overvoltage away from connected equipment.
What to inspect first
Panel devices provide broad protection but do not replace point-of-use protection for sensitive electronics.
Step-by-step approach
Correct installation and grounding are essential.
Common warning signs
Surge devices have finite service life and status indicators should be checked.
Final checks
Lightning protection is a separate system from ordinary surge protection.
Tools and materials to plan for
The exact list depends on the product and site, but plan for measuring tools, suitable personal protection, manufacturer-approved fasteners or fittings, cleanup supplies and a reliable way to verify the finished work.
Common mistakes to avoid
- Replacing parts before identifying the cause
- Skipping measurements and product instructions
- Using materials not rated for the location
- Closing the repair before checking hidden damage
- Failing to test the completed work
A surge protector is only as effective as the grounding and bonding system it relies on.
Should you DIY or hire help?
A careful homeowner can often handle straightforward maintenance and replacement work. Hire help when access is difficult, hidden damage appears, permits or licensing may apply, or the repair crosses into structural, electrical, roofing or plumbing systems that require specialized experience.
