Both of Bud's citations - guides for laymen

The IEEE guide is aimed at "electricians, architects, technicians, and
electrical engineers who were not protection specialists."


Bud quotes from Martzloff
selectively. Meanwhile this conclusion is so fundamental that
Martzloff makes it the first point in his IEEE paper:

Quotes selectively? How pathetic. w_ forgets to mention that Martzloff
said in the same document:
"Mitigation of the threat can take many forms. One solution. illustrated
in this paper, is the insertion of a properly designed surge reference
equalizer [multiport plug-in surge suppressor]."

In 2001 Martzloff wrote the NIST guide which also says plug-in
suppressors are effective.

Also are those 'scary pictures of plug-in protectors

And lacking valid technical arguments w_ repeats the lie again.

Still missing - a link to any source that says UL listed plug-in
suppressors made after 1998 are a problem.

Still missing - a source that agrees with w_ that plug-in suppressors
are NOT effective.

Still missing - answers to simple questions:
- Why do the only 2 examples of surge suppression in the IEEE guide use
plug-in suppressors?
- Why does the NIST guide says plug-in suppressors are "the easiest
solution"?
- Why do all but one of w's "responsible manufacturers" make plug-in
suppressors?
- Why does SquareD say in addition to their "whole house" suppressors
"electronic equipment may need additional protection" from plug-in
suppressors.
- Why aren't airplanes crashing daily when they get hit by lightning (or
do they drag an earthing chain)?

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