I'm not a professional engineer, so check with the proper experts.

This is what I have done as a US mining hobbyist.

1) You cannot overload your electrical panel. So the limit is 100 A. This is what unusual about mining in that you will be needing power 100% 0f the time. A panel may have more circuits then capacity but in your case you are limited to 100A

2) This 100A will flow through circuit breakers. Circuit breakers are derated by code to 80% of their rating.

3) A 120v circuit uses a 15A breaker. The total available power per circuit is 1800W x .8 = 1440 watts

4) So 100A/15A = 6.67 systems

1440 W is on the edge

One thing about mining is that you can to some degree adjust the power draw down. If you are a gpu miner you can shuffle cards around operate them at a lower power for the most hash per 100A.

Times two, so 13 miners. 14 as I am only taking 11-12A from each circuit?
