2 Solutions:
1) Use glass-fiber cable.
2) MFE -> LVT (<- 3 dot side) -> Miner [Problem is, you'd need to use gold cable between the MFE and LVT so... 2 gold insulated cable x2 + LVT + 4 copper cable = 7 total distance You could either use glass-fiber between the MFE and LVT to get more length, or add a batbox so LVT -> Batbox -> Miner]
Additional Notes: Miners can't support Medium Voltage, so you'll need a LVT between the MFE and Miner regardless.
Haha thanks for helping me out! Umm... Do you know about the EU loss about all cables?
