Surge Protector vs. Plug Strip


Have you ever wondered what the difference between a surge protector and a plug strip is, besides the price doubling?

They look much the same, but they serve very different purposes.

Surge Protectors

Protect only the items that are directly plugged into the device from most electrical surges. It does not suppress or arrest a surge but diverts the surge to ground. Purchase  surge protectors that have an indicating light that alert when it needs replacement. A large surge can disable the protection and cause your surge protector to function as a plug strip.

Plug Strips or Power Strips

Power strips do NOT provide surge protection.

Nether plug strips or power strips can

provide more power to a location, only more access to the same limited capacity of the
circuit into which it is connected.
