I have read that it is advisable to avoid common return when wiring DC for future DCC use. So, on a small shunting layout, am I best to isolate each section and attach via a DPST switch to a single wire leading to the controller (the equivalent of the DCC bus)? In other words, is the attached diagram the best way to approach this? Then, when running on DCC, just turn on all the sections?
Other questions:
- can I use 16/0.2 wire for all the wiring, or should I use something heavier for the main wires to the controller?
- I will be using SEEP PM1s on PECO electrofrogs modified to live frog. Can I wire the DC 16v element of this with a common return?
- is there anything else to be aware of?
Thank you for all help and advice
