Under the incoming power meter, I have a 200a main breaker with #2 130a rated cable leading to a 125a sub-panel. From the sub-panel, there are four 50a 2 pole breakers supplying power via a 63g (65a) wire to four park model manufactured houses ranging from 106' to 48' distance from the sub-panel. Is this a workable set-up or does it require change

What concerns me is the #2 wire connected to a 200 amp breaker. Is that true?

If it was a full 200 amp service, which is questionable, and for the purpose of model homes, you should not have a problem.

#2 wire fed by a 200 amp breaker is a serious problem.

I would also question supplying power to multiple residences off one panel. Where are you located ?

They are model homes, just for show, not actual residences.
