I was guessing that the transmitter might actually use more than 200a and the paralleled conductors did come back to a single disconnect. I still don't see a problem since parallel sets of 3/0 in separate raceways would not shock anyone as long as all the rules were followed. Putting a meter in each set would not change my opinion if the meters were the same so the load stayed balanced. It would become apparent pretty quick if there was an imbalance because the meters would not read the same. I'm sure they will drift apart but it might be interesting to see how much and if it is a constant rate.
