Default DIY surge protection...

Try to prove that. You can't, because it's another factoid you created with
a box of Ex-lax.


So many spiteful accusations. So little knowledge by first
learning. He constantly posts accusations without learning the
technology. So again, more facts without insult from one who learned
this stuff before posting.

In the late 1950s, Bodle and Gresh monitored surges throughout the
country. For example, over a six month period in Mt Freedom NJ, that
one cable produced 1120 longitudinal surges during 36 thunderstorms.
About 31 surges per thunderstorm per cable.

In the mid 1975, Carroll and Miller repeated this study. Over six
months in Washington CT, 1230 surges were recorded during 23
thunderstorms on that one cable. Average was 53 surges per storm per
cable. Some storms exceeded 100 surges per storm. One storm created
so many surges that the system ran out of film.

But Michael Terrell just knows this cannot be. He feels. Therefore
he knows. Which is what so many do to know plug-in protectors are
effective and to justify personal attacks. Clearly those papers in
the Bell System Journals were wasting time. They too should feel
rather than waste money on research. Clearly feeling justifies
malevolence.

Back to reality. COs suffer hundreds of surges without damage -
because that technology was understood even 100 years ago when a
carbon block protector was first patented about 1880. Protection is
always about where energy dissipates. A protector is only as
effective as its earth ground.
