Default Electrical Question

Surge protection requires earth ground. Safety ground of
those outlets does not provide an earth ground necessary for
effective surge protection. Therefore that plug-in UPS only
protects from power loss - does not protect hardware.

To understand why outlets are not earth ground, one must
first learn the concepts of impedance - not the same as
resistance. Read that UPS specification. It does not even
claim to provide protection from typically destructive
surges. It claims the exact same protection found in power
strip surge protectors.
