Well have a confusing situation going on which I believe is the ZW I'm using ( I have 3 of them) for the 3 main lines the trip is going as if I'm running my 3 engines 2 PA-1's ( dual motor) and my tmcc hudson it will trip the breaker in the transformer never did this befor this just started I tried running just two engines ( the PA's) and it was fine added the steam all was fine for about 2 to 5 minutes tried running the staem one PA all was fine add second PA and fine for a short bit then it trips
So later need to change out A ZW and see if it happens to that one also. Could it be to much for the Transformer 5 motors?
