Three circuits in one outlet box

[smallfish]

Does this installation break any code rule and if so which one?

Three 20 amp 120 volt individual branch circuits are required for three microwaves on a countertop.
I've run a multiwire branch circuit (120/208 volt) to a four inch square box. On a raised cover are two duplex receptacles. I plan to break the tab on the hot-side bus of both duplex receptacles and land the three hot conductors each to a receptacle leaving one receptacle without a hot wire. The neutral wire will terminate on the ungrounded side bus without breaking these tabs.
Therefore, there will be three individual receptacles for use.
Thanks

If the voltage was 277 on different phases you would need a devider. Your okay with 120 . But you do have to keep your neutrals straight. If your sharing a neutal you would of course need a two or three pole breaker. Some one will chime in with code references....
