w_ has a religious belief (immune from challenge) that surge protection must use earthing. 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. Plug-in suppressors do not work primarily by earthing (or stopping or absorbing). The guide explains earthing occurs elsewhere. (Read the guide starting pdf page 40).

Why does Bud recommend an ineffective
solution that is irrelevant to the OP's question?

My only recommendation was: “I agree with w_ that ethernet between buildings should connect to an entrance protector at each building“ and short connection of that protector to the earthing wire at the power service. Or fiber.

I made a comment in passing about plug-in surge suppressors in response to w_’s ‘magic box’ nonsense. But w_ has to defend his religious belief in earthing.

The religious mantra #2.
Everyone is for earthing. The question is whether plug-in suppressors are effective. Both the IEEE and NIST guides say they are effective.

w_ still has not provided a link to a source that says plug-in suppressors are NOT effective. There is only w_’s opinion based on his religious belief in earthing.

Never answered:
- 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"?

Bizarre claim - plug-in surge suppressors don't work
Never any sources that say plug-in suppressors are NOT effective.
Twists opposing sources to say the opposite of what they really say.
Attempts to discredit opponents.
w_ is a purveyor of junk science.
