This may be covered somewhere but I'm new here so hope you will bear with me.
I have 3 Asic miners and think it will be more efficient to run 220-240v so am trying to determine how to use the range plug which is on a separate circuit and split it into 3 or 4. I thought I would just use a range cord 10-50P (3 prong non-grounded) and wire it into a splitter like this
https://www.amazon.com/Conntek-1-5-Feet-Connector-Generator-Extension/dp/B005HSK29E but am not sure how the 3 prong non-grounded wire would be used in a conversion to a ground plug where the 3 prong has 2 120v and one neutral. Anyone?Thanks
