A Hint Peter. I have, scattered about my premises, a dozen or more of
those 3 foot long plugin extension strips with 6 to 8 sockets, a cheap
circuit breaker and surge absorbtion (65+ Joules) built in. 20 years ago I
used to lose a modem every time mother nature put on a show. So I first
went through this room and made sure all the wiring was tight, and properly
phased. Then I bought one super deluxe version of this gizmo, plugged it
into the duplex behind this desk and hung it on the wall about 4 feet from
me. It has connections for cable tv and telephone too, so all circuits are
protected by the devices 5500 Joule surge absorber. Except for the X10
stuff and the overhead lights, everything else in this room is plugged into
this as a central, common point. If lightning does strike, then the whole
rooms electrical stuff "bounces" in unison.
Now I do not have cable anymore, so I have only the 8 or 9 channels I can
get from a roof mounted, rotating antenna, which is itself grounded from
its base and all 4 guy wires. There is a telco type lightning arrestor
connected by 2 feet of 8 gage to a ground rod, as is the coax from the
antenna. With lightning arresters on the rotor cable as well as the coax,
I saw evidence of a strike on the antenna the wind took down last June
24th, but it didn't get past the grounding and the arrestors.
But its been 15 years since I've had any lightning damages, including
seeing the pole with my transformer on it take a good hit at least once.
The rest of the house is similarly equipt with these surge arresting
circuit expansion strips too as I've made sure any wiring expansions or
such that I have done are so equipt.
I sleep better when the weather gets ugly. I seem to have the damages
under control. Extra expense over about 20 years might be $150.
Cheers, Gene
