Dear Ed and Janet,
Do not EVER tie them together! When lightning strikes your tower, and it
WILL, you will have upwards of 100000 volts destroying every electrical
device in your home from the ground lead of your electrical system during
the 15 -50 milliseconds that it takes for the voltage to bleed off into the
ground system!! Many textbooks recommend tieing these together, but they are
in ERROR!! Save yourself a lot of money and more trouble than you can
imagine!
If you tie them together and you take a strike, the following is a list of
what you can expect to replace:
(even if they are turned off at the time of the strike because the voltage
is so high that it jumps the switches)
Air Conditioner (inside and outside unit)
Refrigerator
Dishwasher
Oven
Microwave
Television sets
Amplifiers
Radios
Computers
Can Openers
Clock Radios
Light Bulbs
Doorbells
Stereo Amplifier and Receiver
Garage door opener
Security System
All in all, over $20,000 in damage on two strikes 6 days apart. Whereupon I
realized the error and cut the link out with a boltcutter and solved the
problem!
Sincerely,
Kirby

Subject: [TenTec] Another grounding question
What is the thinking on grounding the tower ground to the ground coming into
the house at the power, 220 service entrance? Tie them together or not? Ed
