SquareD says for their "best" service panel protector "electronic

Correct. I bet westom will claim this fact is propagandag



I have no doubt in my mind it's the product of SquareD company lawyers

wanting to make sure they can point to it when someone's stuff gets

damaged. "Look, we warned you!!!! and you failed to have a Plug-in.

And now go sue the Plug-in people because they were the LAST line of

defense so if your product was damaged is was THEM not US."





The SquareD connected equipment warranty $ is double when the service

panel protector �is used in conjunction with ... a point of use surge

protective device.�



The NIST surge guide, written by someone who has researched surges and

surge protection (with many published papers), suggests that most

equipment damage is from high voltage between power and cable/phone/...

wiring. A service panel protector does not, by itself, limit that

damage. The quotes from SquareD are consistent with what is written in

the IEEE and NIST surge guides. They come from electrical engineering.

I would just add that the IEEE guide is not just written by just one pro.
It's written by a panel of five and it cites the contributions of many others as well.

"The IEEE Surge Protection Devices Committee (SPDC) has been writing
Standards for lightning and surge protection for more than 30 years. The current
versions of the IEEE C62 Family of Standards represent the state of the art in
these areas.
This application guide was written to make the information developed by the
SPDC more accessible to electricians, architects, technicians, and electrical
engineers who were not protection specialists."
