Service panel suppressors are a good idea.
But from the NIST guide:
"Q - Will a surge protector installed at the service entrance be
sufficient for the whole house?
A - There are two answers to than question: Yes for one-link appliances
[electronic equipment], No for two-link appliances [equipment connected
to power AND phone or cable or....].

"Protectors in series" assumes protectors will somehow stop and
absorb what three miles of sky could not even stop.

Because of his religious blinders poor w can't figure out how plug-in
suppressors work. As the IEEE guide explains for anyone that can think,
it is by clamping.

A protector is only as effective as its earth ground.
No earth ground means no effective protection

w's religious mantras protect him from conflicting thoughts (aka reality).

w just repeats the same drivel, as if repetition makes it true.

Still never seen - anyone that agrees with w that plug-in suppressors
are effective. (Because no one agrees with w.)

Still never answered - simple 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"?
- Why does the NIST guide say "One effective solution is to have the
consumer install" a multiport plug-in suppressor?
- How would a service panel suppressor provide any protection in the
IEEE example, pdf page 42?
- Why does the IEEE guide say for distant service points "the only
effective way of protecting the equipment is to use a multiport
[plug-in] protector"?
- Why did Martzloff say in his paper "One solution. illustrated in this
paper, is the insertion of a properly designed [multiport plug-in surge
suppressor]"?
- Why do your "responsible manufacturers" make plug-in suppressors?
- Why does "responsible" manufacturer SquareD says "electronic
equipment may need additional protection by installing plug-in
[suppressors] at the point of use"?
- Where is a source that says protection is "inside every appliance"?
- How do you protect airplanes from direct lightning strikes? Do they
drag an earthing chain?

And (with some overlap):
1 - Do appliances and electronics typically have some built-in surge
protection, eg MOVs? Yes or no.
2 - If the answer to 1 is yes, which we all know to be the case, then
how can that surge protection work without a direct earth ground?
3 - How can aircraft be protected from surges, caused by lightning or
static in the air, since they have no direct earth ground?

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