I'm also interested in this. I have a few questions that I'd like to tack on.

I'm hoping to run two AntMiner S9s with either AWP5s or AWP3++s to power them. Along with figuring our what receptacle should be installed, I also want to know what amperage the line should be rated for. Do I need a dedicated circuit for each power supply?

Are there recommendations on which PSU to use?

Edit: I'm in Ontario, Canada, if that makes a difference.
