Thanks to "Sparky" and Bennie for the input. I started this thread to get various ideas from others and to bring up some things that weren't thought of.
Bennie;
I am building on the topic that we had going in the old Holt forum. To me, it was prematurely cut short. It also brought grounding techniques to the attention of others [was apparent from their input].
Would like to get as many of these types of threads going in this forum as possible, since it will have a large amount of Contractors and trades persons visiting.
Any input is great.
BTW: I will try making a 1 line drawing to attach in a message. It can describe the grid method's connections so the consept is more understandable.
