Silly questions...but these miners are single phase right? So when a 3 phase distribution panel is used it will need to be balanced for single phase? Thanks.
That is the general rule for using a 3phase supply to single phase load. You really have to balance it. Distribute the load and connect it to lines 1-2 ; then lines 2-3 and lines 1-3. Provide grounding too for protection.
You can order a distribution panel with a 3 phase supply and single phase load to the manufacturers. They will balance it out according to number of circuits you want.
