wiring my buss in ho scale

[nickyb]

Leads are in now I'm starting the main buss layout 12 x 16, what size will carry. I have enough 14ga on hand is that too small.

I will assume you mean in HO scale, and that all you will want the bus to carry is maybe 8 amps maximum.  In that case, 14 gauge is ample.   Your feeders can be as light as 22 gauge provided they are kept short, say 20-24" and under.  Try for a pair of feeders every 6' of rails.

I used 14 gauge wire on my 22' x 42' layout and it works just fine.

I concur with the others.  14 gauge is more than sufficient.   I used 14 gauge for a bus on my last couple layouts and I am going down to 16 for the next one.
