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

I am not sure if you are from U.S where everything seems to be measured differently , but talking from an international standard of electricity , a 3 phase set up usually comes in 4 wires  ( 3 phase and 1 neutral wire ) . now anything you measure between the neutral wire and the phase is 220v ( based on 3 phase = 380V). which is the exact set up i have here.

so what you have to do is.  get 3 main circuit breaker , connect each phase ( wire that is not neutral ) to 1 breaker. and then you going to treat each of the 3 breaker as a different source of 220v, of coz do not forget to pass the neutral to every breaker as well.

excuse my poor vocabulary but i hope you get the picture.
