Snipped preceeding discussions.
I have a similar situation, except my modular sits on a Ufer cage basement
(Concrete Encased Ground System, and then I have 18" wide steel I-beams
overhead. The service grounds, etc. are all tied to the Ufer and an outside
ground rod at the south end of the house, while my shack is at the north end
(40' away). My sub-soil is cobble stone and river rock with sand, and near
the house (3' out our so) seems to be damp most of the year. Can I make the
I-beam directly over the operating position the ground plate for the shack?
Other ideas?
