Re: Building a mining farm; a few electricity logistics questions
Best thing to consider is either separating loads on individual circuits, or running a high amp (like a 30 amp) and run it into a sub panel with some 15 amp circuits, Then run a strip on each circuit.
That's what I did for my electric homebrewing setup:

It splits four 120V 15A circuits out from a 240V 30A dryer outlet:
This probably should've been built with some circuit breakers. For use with a mining farm, you could easily replace the switches with circuit breakers. Depending on how many machines you intend to put on each circuit, you could also add more outlets and dispense with the power strips.
