Maybe W_ would like to explain to us how it is that surge protection
INSIDE an appliance is usefull in preventing damages from surges, yet
a plug-in protector won't provide any protection.

If protection inside an appliance accomplishes what a plug-in
protector does, then why waste so much money on a plug-in protector?
..
Still never shown – that there is protection inside even a significant
percentage of appliances.

Still never answered - trader’s question above.
..
a protector is
only as effective as its earth ground.

And the required religious mantra.

Still no link to another lunatic that agrees with w_ that plug-in
suppressors are NOT effective.

Still never answered - embarrassing questions:
- Why do the only 2 examples of protection in the IEEE guide use plug-
in suppressors?
- Why does the NIST guide says plug-in suppressors are "the easiest
solution"?
- How would a service panel suppressor provide any protection in the
IEEE example, pdf page 42?
- Why does the IEEE guide say in that example "the only effective way
of protecting the equipment is to use a multiport [plug–in]
protector"?
- Why does “responsible” manufacturer SquareD says "electronic
equipment may need additional protection by installing plug-in
[suppressors] at the point of use."
- Where is the link to a 75,000A and 1475Joule rated MOV for $0.10.
- Why should anyone believe there is surge protection "inside every
appliance".

For real science read the IEEE and NIST guides. Both say plug-in
suppressors are effective.
