If I wanted to use two circuits without running extension cords, every place I've lived would mean getting electrical rewired.

If you're gonna get rewired you may as well install a 240v circuit, and some 120v 20a sockets while you're at it.

Fair point.

I'm very close to just running a cord over or devising a way to put my machine closer to a second circuit because my rental is horribly setup and both my bedroom AC and living room desktop (that also doubles as a ML training box) end up on the same circuit.

You can break the tabs on a 15A or 20A duplex receptacle to have (2) single 15A or 20A dedicated circuits on a single duplex receptacle.

It would require an additional run of 14/2G romex (12/2G for 20A) and a single-pole breaker, but allows you to skip cutting in an old work box to add a 2nd duplex receptacle.

You could possibly replace the existing 14/2G with 14/4G which has enough conductors for both circuits.

If you are going to do that, why not install a NEMA 5-20R receptacle, that has two independent circuits and is backwards compatible, as well as being rated for 20A per plug?

The receptacle is the easy part, running the new circuit is the hard part.

Or you know, install a new 240V receptacle.

If I have to:

1) Run wire

2) Get a bigger breaker box

3) To do it legally, hire an electrician and maybe get a permit

Replacing the receptacle is like, <1% of what's involved there.
