Not a stupid question at all. I do have 200 amp service in the home. I looked at pulling additional service, but electrical code in my area says you can only have 1 entry point into the premise. I could upgrade my panel from 200 to 400 though. It will be a while before I go to that length.
I may be wrong in this, but Ive calculated each Antminer S9 pulls a little under 6.5 amps per miner at 220v, which equates to 39 amps for 6. The 6 GPU rigs will pull even less than that, so even with the fans, switch, and other misc equipment, Ill only be using 80-90 amps max.
Right on, as long as you have space in your panel and you don't exceed 200 amps, you should be OK. It'd suck to trip that 200 amp breaker from your mains. All those clocks to reset.
