Complete nonsense.


If not using a 'whole house' protector, well, even 'scary pictures'
created by typically undersized protectors now creates a hazard.


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

And undersized is a red herring. UL requires at least a minimal size.
Suppressors with much higher ratings are readily and cheaply available.


Bud disputes this. Bud says if all wires connect to the same
protector, then surge energy somehow disappears.


Poor w__ is unable to understand the IEEE guide. Clearly explained
(starting pdf page 40) - plug-in suppressors work primarily by CLAMPING
the voltage on all wires (signal and power) to the common ground at the
suppressor. Plug-in suppressors do not work primarily by earthing (or
stopping or absorbing). The guide also explains earthing occurs
elsewhere, not through the plug-in suppressor.


Still never seen - a source that agrees with w_ that plug-in suppressors
are NOT effective.

Still never seen - 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.
