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
