Among my layout's transformers are 2 old ZWs, each powering 2 TIU channels. I use 5 amp breakers on these, which are adequate for running 2 trains each (smoke off). I have 2 more circuits powered by a Z4000, and on that I use a 7 amp because I frequently run 3 trains.

If you run one train, I'd drop to a 5.

Crap....OK I will lower the breaker. I run one train.
