Over the past couple months I had been experiencing some problems with my miner not working at its optimum speed however,  yesterday I fixed it.  (One of the wires to the second fan was damaged)...  Now that it's fixed its working at its full potential..

It is an S7 running at 4.6Th/s

Apparently,  now that it's running at its full potential,  it's drawing more current.  I had it connected to a 2000Watt transformer last night and one of the sockets to the transformer melted.


I switched it to another location today using a bigger transformer (3000watts),  only to know after a couple hours of mining,  the transformer burnt out.


Has anyone been experiencing these problems and how we're they solved?

How do you have your miners connected?
