All appliances routinely have robust protection rated at 600 volts, 1800 volts, 2000 volts, etc. And all feature this protection without protectors.

Last time westom actually provided information on this protection it was
for ESD protection, as in shuffle over a rug and touch the device. That
is a trivial energy.


Surges that are hundreds or thousand joules are routinely made irrelevant by protection already inside appliances.

It is one of westom's fantasies.

Hundreds of joules can not make it over a branch circuit. See the reply
to philo, where a surge expert determined the maximum energy at a
protector in his test series was 35 joules, and most were less than 1
joule. The surges coming in were the equivalent of a 100,000A lightning
strike to the primary wire on a utility pole adjacent to the house.

And it is insane that any appliance can handle hundreds of joules.

Informed consumers spend tens of times less money on a properly earthed 'whole house' solution

And repeating from elsewhe
Service panel protectors are a real good idea.
But from the NIST surge guide:
"Q - Will a surge protector installed at the service entrance be
sufficient for the whole house?
A - There are two answers to than question: Yes for one-link appliances
[electronic equipment], No for two-link appliances [equipment connected
to power AND phone or cable or....]. Since most homes today have some
kind of two-link appliances, the prudent answer to the question would be
NO - but that does not mean that a surge protector installed at the
service entrance is useless."

to even protect those near zero plug-in protectors.

Maximum energy at a plug-in protector of 35 joules with 100,000A
lightning strike - without a service panel protector to protect it.


As usual, I will post the same answers next year since learning and civility appears to cause you difficulty.

As usual westom will post the same misinformation tomorrow and next year.

As usual westom will continue to refuse to answer simple obvious questions:
- Why do the only 2 detailed examples of protection in the IEEE surge
guide use plug-in protectors?
- Why does the NIST surge guide says plug-in protectors are "the
easiest solution"?
- Why does the NIST surge guide say "One effective solution is to have
the consumer install" a multiport plug-in protector?
- Why does the NIST surge guide say "Plug-in...The easiest of all for
anyone to do. The only question is 'Which to choose?'"
- Why do westom's "companies with integrity" make plug-in protectors?
- Why does "integrity" manufacturer SquareD says "electronic equipment
may need additional protection by installing plug-in [protectors] at the
point of use"?
- Why does the IEEE surge guide explain how plug-in protectors work -
and it is not primarily by earthing?
- Why did the investigation by surge expert find only 35 joules (and
usually far less) at a plug-in protector when the surge was the maximum
that will occur?

As usual westom will never have any reliable sources that agree with his
belief that plug-in protectors do not work.

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