I haven't looked at Jim's web site recently enough to remember
his reasons, but here is mine.
We had a shunt mode MOV "protected" power strip at our family
house in New Hampshire. My cousin was using a high power vacuum
while painting. The power strip started smoking and he quickly
threw it outside where it stopped smoking after a while. When I
looked at it, the plastic had be partially melted and there was
a significant danger that it could have started a fire if my
cousin hadn't acted.
It turned out that the electrical system lost its master neutral
connection between the service entrance and the pole. The vac
dragged down the voltage on its leg so most of the 240 volts was
across the power strip's leg. This voltage was enough to pop the
MOV. Since the fault wasn't a voltage spike, the MOV overheated
enough to start smoking.
This whole incident didn't help in my campaign to convince my
cousin that electricity is really safe and you don't have to
unplug all the appliances, including electric clocks, when you
leave the house.
