Everyone is for earthing.  The IEEE guide explains plug-in suppressors 
work primarily by clamping, not earthing. The guide explains earthing 
occurs elsewhere (beginning pdf page 40). The question is not earthing. 
The only question is whether plug-in suppressors are effective.

I didn’t “forget to mention” - it was in my 1st post - phone/signal 
entry protectors must connect with a *short* ground wire to the ground 
at the power service. A voltage difference between phone and power 
‘ground’ can damage equipment connected to both power and telephone 
wires. If w_ could only read and think he would have seen in the IEEE 
guide that if a short connection is not used "the only effective way of 
protecting the equipment is to use a multi****t [plug–in] protector."  In 
many houses the phone/cable entry points are too far from the power 
service to make a short connection.

Provided in my 1st post. Every post since has pointed that out. But poor 
  w_ ignores what does not fit his argument.

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

w_ still has *no* link to another lunatic that says plug-in suppressors 
are NOT effective. Apparently no one in the known universe agrees with w_.

w_ has still never answered 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 guide say "the only effective way of protecting the 
equipment is to use a multi****t protector."
- Where is the link to a 30,000A and 590Joule rated MOV for $0.10.
- Why does the IEEE Emerald book include plug-in suppressors as an 
effective surge protection device?
