The problem is, W_, with his religious beliefs, denies and rants that

whole house protector? For example, those living in a rental
property or an apartment?

A protector is only as effective as its
earthing.

The required religious mantra.

The IEEE guide explains, for anyone who can think, that plug-in
suppressors work primarily by CLAMPING the voltage on all wires (power
and signal) to the common ground at the suppressor. They do not work
primarily by earthing. The guide explains that earthing occurs elsewhere
in the system.


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

Still never answered, embarrassing 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"?
– Why does SquareD say "electronic equipment may need additional
protection by installing plug-in [suppressors] at the point of use."
- Why does the IEEE guide says in its example "the only effective way of
protecting the equipment is to use a multiport protector"?
- How would a service panel suppressor provide any protection in the
IEEE guide example?

For real science read the IEEE and NIST guides. Both say plug-in
suppressors are effective.
