I have a question that I think I know the answer to but just need to confirm. I have a lot of 10 gauge wire that is white. I have a lot of 12 gauge wire that is black. Can the 2 bus wires be different gauges or does that create a voltage issue or some other issue? I am modeling in N scale and have a NCE Power Pro system and a PB 105 power booster. Just trying to save a little money since copper wire has become expensive. Thanks.
For a 5 amp system you should have no problem.

With DCC, the larger the wire the better.
You won't have problems with mismatched wire gauges, the currents or wire runs won't be large enough to be an issue.

Thanks for the info. I'll give it try.
