Industry standard facts and
embarrassing questions.that Bud will ignore to lie and to promote plug-
in protector sales

Lacking any valid technical arguments poor w_ has to try to discredit
opponents. My only association with surge protectors is I have some.


1) How does that plug-in protector provide protection without the
'always necessary' earth ground? What does a protector do? Bud
provides only two citations. Both disagree with his claims. The NIST
bluntly defines what a protector must do - Page 6:

What does the NIST guide really say about plug-in suppressors?
They are "the easiest solution".


2) Bud not only denies this also so important single point earth
ground.

If w_ could only read he would have seen my emphasis on a *short*
'ground' wire from phone/cable entry protectors to the 'ground' at the
power service. w_ appears to want all wires run to the grounding
electrode. That does not provide the minimum voltage between power and
signal wires. Martzloff has written "the impedance of the grounding
system to 'true earth' is far less important than the integrity of the
bonding of the various parts of the grounding system."

And the case where phone/cable entry points are too far distant from
power service, IEEE guide says "the only effective way of protecting
the equipment is to use a multiport [plug-in] protector."

He also ignores what happens when a protector is too far from
earth and too close to appliances. Page 42 Figure 8: the surge
earthed 8000 volts destructively through appliances. This is the
second point from his citations that Bud must ignore.

The illustration has 2 TVs. The IEEE says the point of the illustration
is "to protect TV2, a second multiport protector located at TV2 is
required." Way to complicated for w_.


3) So if a plug-in protector is effective protection, then
manufacturer specs will list each type of surge and protection from
that surge. Bud never provides that spec either.

"Each type of surge" is nonsense. w_'s favored SquareD service panel
suppressors do not have specs for "each type of surge". Lacking valid
technical arguments has to invent problems.

Plug-in
protectors don't claim to protect from the type of surge that
typically causes damage.

Complete nonsense.

Not one plug-in protector manufacturer will
claim that protection - made obvious because Bud will not post those
specs and ignored over 400 requests for those specs.

Over 400 requests - another hallucination.
Specs posted often and ignored.


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

w_'s religious belief (immune from challenge) in earthing has been the
elephant in the closet. w_ believes a surge protector must directly
earth a surge. Thus in his view plug-in suppressors (which are not well
earthed) can not possibly work.

The IEEE guide explains plug-in suppressors work by CLAMPING the voltage
on all wires (signal and power) to the common ground at the suppressor.
The voltage between the wires going to the protected equipment is safe
for the protected equipment. Plug-in suppressors do not work primarily
by earthing (or stopping or absorbing). The guide also explains earthing
does occur, just not primarily through the plug-in suppressor. (Read the
guide starting pdf page 40).

For accurate information on surges read the IEEE and NIST guides. Both
say plug-in suppressors are effective.

There are 98,615,938 other web sites, including 13,843,032 by lunatics,
and w_ can't find another lunatic that says plug-in suppressors are NOT
effective. All you have is w_'s opinions based on his religious belief
in earthing.

Embarrassing questions that w_ will igno
- 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)?
