So I'm planning for a small farm setup to accommodate 25 S19J Pro 100T in the beginning with room to expand up to 50 units in the near future
As per Bitmain, each unit draws about 3000w at 200~240v and the power supply has two inputs.
A 20amp circuit at 240v can handle up to 3,840w at 80% load
A 30amp circuit at 240v can handle up to 5,760w at 80% load
Considering this, is it safe to use 20 amp circuits for each antminer instead of going for 30 amp ? Thanks all

Cool cool, with that much power I can somewhat assume this will be a three phase power coming in. Three phase generally comes in at 208 pole to pole and 120 pole to neutral (WYE). If you bring in 480v you can get a 230 volt transformer but will loose the 120v capability (DELTA). Personally I would run the delta config tapped a little over 240 volts.
