The answer to 'surge protection replacement schedule' is that surge protectors should be replaced every 3-5 years, or whenever they show signs of wear or damage. Surge protectors are designed to absorb and divert excess electrical current during power surges, but over time the internal components can degrade, reducing their effectiveness. Replacing your surge protectors on a regular schedule helps ensure your home and electronics are properly protected.
Most manufacturers recommend replacing surge protectors every 3-5 years, but this can vary depending on the quality and usage. Surge protectors that are used to protect sensitive electronics or that experience frequent power surges may need to be replaced more often. It's also a good idea to replace any surge protectors that become damaged, discolored, or feel hot to the touch, as these are signs that the internal components are failing.
