I'm sure this question has been asked more than once, but I'm not really finding anything good when I search so here goes...
I have a server-grade 220v PSU (I do not yet have a C13 cable for it), and a 220V (double throw) 20A breaker. The breaker is in a subpanel but unwired. I need to wire up a receptacle (or ideally, two receptacles), and then purchase a cable for the PSU.
My questions:
What kind of wire do I need coming from the breaker to the receptacle? (12/2? 12/3?)
What kind of receptacle should I buy?
I assume, based on the receptacle it should be fairly obvious which type of C13 power cord I will need.
Thanks!
Edit: forgot to mention, I'm in the USA.
