I'm looking for an electrical coupling to provide 120VAC

only turn one way, so it can't have wires up the hub.

Is there a commercial product out there, and if so, what
is it called? None of the electrical places I talked to
knew of anything like this...

Think battery on the turntable. Lot less effort.

If the equipment on the platform uses about 10 amps at 120V and runs 10 to
12 hours a day, what sized battery would you use? Do you think D cells are
big enough?
