So, the electrician is coming tomorrow morning to get me set up to mine with x4 S9's. I am still a little unclear as to whether or not I can put all 4 miners on a 30AMP circuit, but I don't know what other choice I'll have. My concern now it that the APW3++ PSU are 1600W. Does this mean they are always running at 1600W or that is the maximum that they run at? I will be receiving the late November batch of S9's and they are rated at ~1350W. Thus, 1350 x 4 = 5400W. If the 30A circuit has a voltage of 220, then that is 6600W....5400W/6600W = right around 81%. Close enough to run continuously with no worries? However, if I am wrong and the PSU's are always running @ 1600W, then putting 4 on one 30A circuit may not work. Can someone please clear this up for me? Do the APW3++ run at 1600W always? Or, is that just the maximum that they run to accommodate whatever device they are dowering?

Thanks in advance!
