Many 'experts' forget to first learn basic electrical concepts. Reality is not found in soundbytes. Unfortunately reality must be explained in long replies - and with numbers.

Wire is never a perfect conductor as you only assumed. Wire is always an electronic component. Telcos need 'whole house' protectors as much as 50 meters distant from $multi-million electronics. Wire impedance (increased wire length) increases protection. A homeowner needs a 'whole house' protector connected within feet of earth ground - because wire impedance must be low. Basic electrical knowledge also says why a hardwire to earth must have no sharp bends, no splices, and not inside metallic conduit.

Obviously a wall receptacle safety ground does not have low impedance. Obviously it is too long, has many sharp bends, multiple splices, and can be inside metallic conduit. Other educated by advertising would not know these basic and critical electrical concepts.

Your denials demonstrate no experience. You did not even know what impedance is. Low impedance is critical to have surge protection.


I know what impedance is. Here's what I've asked you many times before
and you cannot explain. You claim that surge protection inside appliances,
TVs, etc is just wonderful and very effective at dealing with surges. You
claim that a plug-in surge protector at the TV is totally ineffective
because of your impedance rant above. So, how can one work so well, yet
the other, operating under the exact same limitation, not only can't work,
but is dangerous?

Of course the insanity here is that the MOVs inside a typical plug-in
surge protector are much larger than those in the TV and can handle
much larger surges without failing. And the plug-in
surge protector, it can be replaced for $15. How much does it cost to
replace the MOVs inside the TV?
