Yup looks like that would work. Me personally I would just save the original outlet, replace it with a NEMA L6-30 and switch back to the original before I move out.

However that adapter cable should be fine. I have seen some priced a lot more expensive but that one isn't too bad (outlet would be cheaper).

Remember continual load is 80% of peak. So 240 * 30A * 80% = 5,760W (5.76 KW). You shouldn't push it beyond that. Most PDU w/ NEMA L6-30 plug will indicate they are rated for 24A (30A * 80%).

I did just find this that should let me use a L6-30 PDU on the 14-30 outlet...

That's what the dryer plug is that we have here.

Other reason I considered this is the landlords being a dick about having a 220 put in that I'd pay or so they can't say shit about me using an existing one for my BTC equipment.

Basically I ill have 9 Prospero X1's and three X3 modules I will need to power for a total of 3.9Th/s

By three X3 modules I mean 1.5 X3's... has to do with their compensation package... just so there's no confusion thinking I will have 3 full X3 units to power lol.

In regards to 2, most lines are advertised 240v these days but most items like miners are advertised 220, or the sake of argumnt... any issues there ?

No. This is just a (mis)naming convention. In the US 220/230/240 are the same thing (and so are 110/115/120). Even most PDU designed for 208V single phase will work at 240V (208V single phase is common in data centers but uses same wiring, outlets, and plugs as 240).

They don't exist. They were never intended to be used with an outlet like that. In the US virtually all 208V/240V PDUs are NEMA L6-20 or L6-30.

You may be able to id the plug here.

1) You can use a smaller PDU. Understand no PDU uses the same plug as a dryer so you will need to change the outlet. Also most dryer plugs in the use are actually split voltage 240 & 120 in a single plug you are only intersted in the two "hots".

2) No. A 240V PDU outputs 240V.

I know that about the outlet, I just checked, looks like a stander 120 in supersize with an L shaped piece below what would otherwise be thee round prong on a 120 plug.

I've seen / had dryers with both three and four prong plugs.

Not sure how old the plug is / when it was put it but it would have had to be within the last 10yrs, so not sure on how it would be wired exactly.

Speaking of the outlet, can't I just find a PDU with a four prong plug or don't those exist ?

Ok, so we have in my house 220/40 line for an electric dryer we don't use that's on if I recall correctly, will need to double check, a dual arm breaker consisting of two 30a switches.

1) Does the PDU need to match the total available amperage of the breaker ?
--- Will say a 24a PDU work just fine on a 220 line consisting of two 30a breakers ?

2) Will something that's say made for 120v line work on a PDU connected to a 220 line ?
--- The question itself seems obvious but I don't know how the PDU's work exactly, like does each plug down convert to 120 but is just connected to the 220 line for higher draws.

3) There was one other thin but it's slippin my mind right now...
