A lot of words, but none respond to my comments. Sure, a whole house

apartment dwellers or those who rent their home.)

For some folks, point of use protectors may be sufficient.

Where does a 'point of use' protector make that short connection to
earth? If a plug-in protector is protection, then your post makes
sense. However the protector is not protection. It is only a
connecting device to protection. Lots of word repeatedly demonstrate
why plug-in protectors would appear to be a complete solution but
don't even claim to be protection. It only claims to be a protector..

In an apartment, modify a plug-in protector to act more like an
effective 'whole house' protector. First, cut its power cord as short
as possible. Every foot on that power cord means diminished
protection. Find a wall receptacle that is electrically closest to
the breaker box - minimum number of splices, shortest distance, etc..
Plug that 'short power cord' protector into that receptacle.
Hopefully a breaker box earth ground exists. What makes a protector
better? Increased distance between the protector and electronics.
Decrease a connection length to earth ground.

A protector without earth ground does nothing sufficient. It is
only a protector - a connecting device to protection. A protector
without connection to protection does nothing useful.

If a 'magic box' was sufficient, then it would claim such protection
in spec sheets. Why no such claim? Why is a 'magic box' that does
not even claim to provide protection also called sufficient? The plug-
in protector without earthing is not sufficient for anyone. The
protector is only as effective as its earth ground. Or do we know it
is protection only because it is called a protector?
