All of my power supplies are now Enermax Platimax or Enermax MaxRevo's.  I got tired of waking up in the morning and seeing that a power supply failed and my miner didn't mine all night.  Learn from me. Just get quality power supplies from the start.

30 Amp circuit will not work because of the plug.  Most plugs (wall sockets) are 15 Amps and the ones with the little 90 degree T on one side are 20 Amps.

So the best way to do it is like this:

(1) 20 AMP Breaker, (1) 20 Amp Plug (wall socket) per machine.  Each AMT will draw 10 to 12 AMPs.  That is to say, you will only be using 12 Amps of a 20 Amp circuit/plug.  This way you never have to worry about blowing circuits etc. You're electrical is now bulletproof.  Building it right from the start will save you time and headaches in the future.

****No I'm not an electrician  

Did anybody get a tracking number for their DIY Kit yet?  Hoping to get mine soon.

Can you take a screen shot of what it looks like?  That is to say is there a higher option setting that you can just remove the ###?

I was thinking 1500W PSU also.  If Bitmain is using the same chip and their claim of 1000W at the wall is correct, this machine may have some room to run.  I don't suggest leaving the cover on though.

How much of the kW are you using and what are you using for cooling.  I'm running 26 S1's overclocked right now and found out the hard way on what it takes to keep them cool.  I plan on getting a few s2 whenever Batch 3 opens up but would never place more than 5 evenly spaced in a cabinet. I would worry about 10 x 1kw machines on top of one another.
