Whole-Home Surge Protection vs. Power Strips: What Homeowners Need to Know
What plug-in power strips are designed to do and how whole-home surge protection takes a different approach.
Originally published Guide updated
This updated guide retains the topic and publication record of a prior SoCal article; the guidance has been rewritten for the new site.

The devices protect at different points
Plug-in devices are used at individual outlets, while whole-home surge protection is installed at the electrical distribution equipment. They serve different positions in a layered protection plan and are not interchangeable in every situation.
Panel compatibility matters
The protective device, panel, installation location, and existing electrical conditions should be reviewed together. The electrician should also explain any grounding or equipment concerns observed during the visit.
Set realistic expectations
Surge protection can help reduce risk, but it cannot promise that every event or connected device will be unaffected. Homeowners should review equipment instructions, warranties, and any additional protection recommended for sensitive electronics.
