And General Electric, Square D, Keison, Intermatic, Cutler-Hammer,
Siemens, ... and maybe another 50 responsible manufacturers whose
products put money into protection - not profits.
All of those manufacturers say plug-in suppressors are effective.
What happens when they magically absorb
surges?

The lie repeated.
No source say there is a problem with UL listed suppressors that have
been made since 1998.
No source even says a damaged suppressor was UL listed.
Meanwhile, the OP's
questions are about earthing.
The OP's questions are about adding a ground for outlets.
A protector is only as effective as its
earth ground.
w only understands sound bites.
Still missing - a source that agrees with w that plug-in suppressors
do NOT work.
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?
For real science read the IEEE and NIST guides. Both say plug-in
suppressors are effective.
