I use this PDU to plug multiple L3s on a single 220 20A breaker.

I currently have 4 plugged in and they're drawing 12A. I am pretty sure I undervolted them years ago, but I forget the details of exactly what I did.

Come off of one your C19/C20 outlets into one of these:

It's this PDU

If you are connecting multiple PSUs or ASICs or whatever it's best to just get a 240V PDU (Power Rail) put in with IEC 320 C13/C14 plugs. Poked around on Amazon and found this one. Only cables you will need are just male to female IEC 320 C13/C14.

I made the mistake of setting up my ASIC room with 240V wall plugs instead of a PDU.

An electrician can do this for a couple hundred. I would recommend buying as much of the supplies needed as you can instead of relying on the contractor to do so; most contractors tend to overcharge on supplies.
