Im an electrician. Its defintiely doable. Just get the right cord which plugs in to your oven receptacle and then the correct adapters for you PSUs and you should be good.
As in a 40A 240V PDU?
Since Ive never done it myself, I can only guess yes. The oven plug is 240V 40A so that would make sense. However, I would suggest get an electrician over to double check before flipping on the switch.
You pay for my flight there and Ill gladly come check it out for you.
I'm not the OP. Just thought you'd know a little more since you're an electrician. I personally run rigs off of two 30A 240V circuits. I have a pdu on each of them which provides enough outlets for multiple rigs. You'll find pdu's in any data center. You can get metered ones that display the amp draw on each bank and you can even get switched ones that will allow you to turn any of the outlets off and on remotely. The big thing is that it provides evenly distributed power over all outlets and provides overload protection.
So my question to you since you're an electrician ... The adapter that he linked to above is not going to provide any overload protection, right? Is there a possibility that he is going to harm his equipment by just using an adapter like that? I personally would never use something like that for this application.
