[TenTec] Earth those feeders

[Stuart Rohre]

If you can get a wire up against the house, but in the dirt just under 
the surface, you can create a halo ground bonding of all the ground rods 
around a house.  Our local utility developed a computer program that 
modeled the losses and in our rocky soil, 10 gauge wire was adequate for 
a sub station, so that should work for a house.  It bonds as it passes 
each ground rod, like main electrical service, telephone entry, cable 
TV, etc.

The size of conductor can vary depending on your total halo length 
circling the house.  And on your local ground character as to earth 
resistance, moisture content, etc.

If you have the area of a 1500 sq. ft. house circuled with no. 10 
bonding all the earth rods, you may not need incremental rods, and the 
soil under you may prevent many rods being driven.  In our local cases 
rock is often 18 inches below surface!
