I've got about 60A of 120v equipment to run in one room (at times, all
of it simultaneously). Currently there's only one 20A circuit feeding
the entire floor. So I was thinking of installing two 30A circuits
and one 20A. I would have three ganged boxes, each holding two duplex
receptacles, and each circuit would feed two of those receptacles (in
adjacent boxes).

However, when reading my books on wiring, I see no mention of any 30A
duplex receptacles...only the single receptacles you might see for an
A/C. I could use all 20A circuits I suppose but would probably need
four. Are 30A 120v duplex receptacles something that exists? Is it
strange to do things this way?

Run a larger cable to the room, and add a subpanel there, with 20 amp breakers
as needed.
