My question to Redsy, would be, why would you even run two, 2/c for a split receptacle ? Second, 210-4(b), says that if this multi-wire goes to the same yoke there shall be a breaker tie, a 240 v circuit with a split recceptacle, and now there are two neutrals in parallel, which are smaller than no. 1/0. Since it is a multi-wire circuit you would only need one neutral.
