120/208V single phase Panel

I have a 120/208V 1 phase generator that feeds an ATS and then a 120/208V 1phase MLO Standby panel. I can't figure out how to make a panel 208/120V single phase. I have been unsuccessful at changing the voltage distribution by using the edit type after selecting the panel. And I can't seem to change it by selecting the connector element in the edit families.

Also, the default 1 phase panel I found in the families is 120/240v Single phase MCB - not sure if that can be altered to make 120/208 Single phase MLO?

208 is 3-phase, isn't it? At minimum it is 2-phase if you connect 2 legs.

240V is residential single phase.

Revit can do what you want. Just make sure what you do actually exists in the real World.

This looks like it works, thanks.

And yes 208 1PH is line-to-line voltage so both the A & B phases are showing on the panel schedule.
