Hi Upnick,
I bought a DCC Bus System from Express Models and the wire sizes are as follows :-
1. Main Bus Wire - 16 x 0.2mm stranded copper.
2. Track connection/dropper wire - 7 x 0.2mm stranded copper.
These wire sizes are the same as those recommended by Brian Lambert on his web site.
Trust this helps.
