Hello,

I'm located in Missouri and I'm in the process of upgrading my bitcoin mine to get about 300 kilowatt of power.
Need some help with figuring out what's the best option for me.
My cooperative power company give me two three phase transformer options.

Option 1. 277/480V 4 wire wye
Option 2. 240/480V 4 wire Delta

Option 1 will require a second dry type transformer to go from 277/480V to 240/415V Wye so will be a bit expensive.
Option 2 will not need a second transformer, since I can get 240volts from between line and neutral. This option seems too good to be true. Is there a catch here? Am i missing something ? This is a high leg delta system and I wonder if there are some inherent downsides to it, since most miners seems to prefer wye systems.
