A power strip protector is no different from any other non-
protector power strip when 120 volts remain below that 330 volts.

You're right, Michael. This guy has no idea what's he talking about.

It's worth repeating what the fire marshal told me... Cheap power strips
(whether or not they have surge suppression) often have cheap breakers.
These can develop sufficiently high resistance to the point where they
overheat, even when the current draw is less than the maximum specified. He
said they were a relatively common cause of fires.
