thanks everyone for the help
i have 3 phase each with 80A switch for each phase
the street fuse has 100A for Each phase
in this case how many miner can i load for each phase
thanks
13 miners (1300W) on each phase (230V)
Total 39 miners . But the 80A main fuse can begin to turn off , without extra cooling. I recommend a separate cooling fan for main fuse or less miners.
