So you get a good surge from nearby lightning, and the three wires on your
computer's power plug all go to a common-mode voltage plus or minus line
voltage. But your ground is bad, so you have a common-mode voltage about
4,000 volts above earth ground.

And you're touching the computer, or you have a telephone line plugged
into it, or an Ethernet wire from another location, or somehow have
one of many other possible and even likely scenarios in which the other
end of the person/line is grounded fairly well. 4,000 volts on one end
and ground on the other... bring the weenies and marshmallows.

Not all the protection is meant for the device plugged into the strip.

Meanwhile, Bud's own citation shows a TV being destroyed by more
voltage - 8000 volts - because of the power strip protector. Bud
claims that is proof of an IEEE recommendation when IEEE makes
recommendations elsewhere - in Standards. Multiple IEEE Standards
define one thing for protection - earthing.

Go to Adobe page 42 (paper page 33) to see Figure 8. TV2 is
destroyed by 8000 volts because earthing was defective and because
protector was too far from earthing.

8000 volts on a TV - that is called effective protection? Never
was.
