Plug labeled 250v/50a. Help identifying and using.

Good afternoon BC Forum! I have a rather unusual plug in my garage where I am going to be setting up a couple s9's very soon.

I was hoping that the kind people from BCF might have seen one of these before and can guide me in what to do next.

I am curious if it is safe to use, and what would I need to do in order to hook up several s9's with apw3's from bitmain directly.

I googled around a bit about this plug but most of the ones I see people have look slightly different from this one.

Anyhow, I appreciate you kind folks taking the time to read and look at this. Any help, info, and advice is greatly appreciated.

That is a NEMA 6-50R outlet - it is usually commercial grade.  It is commonly used for welders.
he one looks like an Eaton product:

The receptacle is rated for 50A 250V but the real question is how is it wired and what breaker is installed on it.
If you are not sure, it would be a very good idea to hire an electrician to at least look at and see if it is safe.
If it is a 50A 240V circuit, then you could plug a PDU to it and power at least a couple of S9s safely - I would guess four (or MAYBE five) of them if they draw 7-8A each.

Again, having an electrician in to look at it would be smart and should not cost that much if they are just looking at it for you.

Ok I will look into that. Thank you very much for taking a look at it for me.
