Ok, I understand. This is a track fitment stage.
The wiring method suggested to you sounds ok. I like alternating the common wire to have both outside rails with common. Every 40 inches may be too many.
I use a 120 inch - 144 inch spacing between power connections.
How did you do it on the previous layout? It was operating properly before it was disassembled, yes?
How do you connect the 180 watt transformers? Did you make an adapter wire for the Molex plug or did you cut it off? I am asking because I want to be sure that you can identify the Hot (red) and the Common (black) wires of the 180 watt transformer.
