A protector is only as effective as its earth ground.

And the same religious belief in earthing. Everyone is for earthing. The
only question is whether plug-in suppressors are effective. Both the
IEEE and NIST guides say they are.

Still missing - link to another lunatic that says plug-in suppressors
are NOT effective. Still only w_’s opinions based on his religious
belief in earthing. Why can’t you find any links w_?


TV coax cable does not even need a protector. A properly installed
cable is earthed directly - no protector - where it enters the
building.

Doesn’t need a protector? The IEEE guide says “there is no requirement
to limit the voltage developed between the core and the sheath. .... The
only voltage limit is the breakdown of the F connectors, typically ~2–4
kV.” And "there is obviously the possibility of damage to TV tuners and
cable modems from the very high voltages that can be developed,
especially from nearby lightning." A plug-in suppressor will limit the
voltage from core to shield.

As usual w_ is at odds with the IEEE guide.


Still no answers to 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"?
- How would a service panel suppressor provide any protection in the
IEEE example, pdf page 42?
- Why does the IEEE Emerald book include plug-in suppressors as an
effective surge protection device.
- Why don’t favored SquareD service panel suppressors list “each type of
surge”?
– What are w_’s connections to surge protection equipment
manufacturers? Specifically ZeroSurge?
Why no answers to simple questions w_?


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.
Invents opinions and attributes them to opponents.
Attempts to discredit opponents.
w_ is still a purveyor of junk science.
