Boys, I believe that there will be no material drop in voltage if I run three sets of 18 gauge feeder wires to each isolated block, and those blocks are no more than about 10 feet of track in total. That's' what I am doing here.
This will allow me to hook up virtually everything from the inside of my control box, while its lid is open and I am standing up, and not underneath the table.
Guess I'm going to be forced to finally go to Harbor Freight and buy one of their El Cheapo Voltometers. Maybe it'll show that I'm wrong. If so, believe me, I will confess and beg forgiveness for my sins! :-)
Thanks
Mannyrock
