My newest problem: I am about to add a 1000 Amp service to my building for running miners, my problem is the service will be 3-phase and the miners run 240v single phase, how do I get from 3-phase 408v to single phase 240v?

I've seen some 3-phase PDUs, is this what I need?

Obviously, I need to balance the load or it will burn the transformer out.

Thanks in advance, Frank
