I have an nscale layout that is being upgraded to dcc. I'm not sure how to run the bus lines. I as thinking of using 16 awg (or do you think 14 awg is better?) for the bus lines. Feeders will be 22 or 24 awg. Would stranded or solid core be better? thanks. I have an idea how to run them but I'm not sure where to start or stop them.
