Can 3 dedicated 20 amp circuits share one 3 gang outlet box?
I need to run 3 dedicated 20 amp circuits to a new sauna from the breaker panel. Is it OK to use one 3 gang outlet box or I have to use each separate outlet box for each circuit? Thank you in advance for your help.

You can have three circuits with three receptacles in a three gang box.

I think that having 2 legs of a 120/240 volt system in a single box (serving separate receptacles at 120-N) required a divider to prevent possible 240 volt exposure. Is that still the case?

I have never heard of that rule. Only divider I have heard is if there is low voltage like phone or Ethernet in the same box.

In a 2012 post on a woodworking forum about wiring a shop in Oklahoma I found this:
but...
My recollection probably came from wiring in New York City and may have been a local requirement.
Even with MULTIPLE circuits, at 120V and 240V there's no NEC requirement to provide a separator in the box.
I believe the inspector was asking for a barrier, which could be the case if you had more than one source. (two independant breakers).

The only time you need a barrier would be when you have wiring from two different electrical systems as you could find in a commercial building. These buildings have both 120/208v and 277/480v systems.
