ECN Forum Forums Code Related Discussion NEC & other Code issues MC question

We have a boat load of 12-4 mc cable which we would like to use up. It was bought at an auction.
One thing we could use it for ( I think ) is to run two 2 pole 208 volt circuits to one location.
Would this be allowed by code ?

Black - White one 208 circuit

Blue - Red one 208 circuit

Green shared ground.

Yes ?? No ?? Maybe ??

Thanks
