Manual transfer switch with two different voltage output feeding a panelboard

I have (4) 2HP motors which need to be backed up by a generator. These motors are duel rated 208V and 230V single phase.

Normal power is 120/208V 3-wire

Emergency power is going to be a 120/240V portable generator.

Would it be ok to have these voltage inputs to be wired in a manual transfer switch and have the output connected to a dedicated panelboard just for the duel rated motors? The output of the MTS will cause two different voltage. A neutral is required for 120V control circuits.

ATS or manual? You contradicted yourself.

ATS must work on 102/208v. Manual shouldn't matter.

I meant to say manual, sorry about that. So basically if the manual transfer switch outputs two different voltages, there is no code that doesn't permit it?
