FYI, after a three year hiatus, I returned to hopefully continue wiring this. It took me a while to figure out where I left off and had a better idea to use color coded feeders based on the color of the blocks. Green & blue for track 2, orange & red for track 1 & brown for sidings & the yard. I also decided to up my wire gauge from 20 to 18 from the CP to the terminal strips. I had to order that gauge as I only had 20 gauge in colors. A place called Del City (that sells auto related supplies) had what appeared to be the best price for 100' spools at $7.35
I'm just hoping what is under the table is enough. Depending on distance, it's a mix of 20, 18 and some 16 gauge for the far distant sections.
I ran some block voltage checks with a auto tail lite bulb 'load' box (four 1/2 amp bulbs) to see which blocks were the lowest. The high to low 2 amp load range was under 1 volt which isn't too bad considering the number of blocks. I did replace a few of the cables to further away lower voltage blocks to equalize the voltage as much as possible. See the attachment;
