People.... THINK about what you are getting into....
If you are asking this sort of question you really need to perhaps pursue other interests...
You are asking how many miners can I power? Fine. Start with:
How many watts of power does each miner need?
A safe answer typically is around 1,400 watts
You say you have 600v 400amp service. Great.
Problem is you have no idea what a 'Watt' is so connecting the dots is

A simple Google search will tell you: Watts = Volts x Amps
In your case you can supply 240,000 watts or 240kw minus your 20% reserved.
You do the math for how many miners that works out to.
And of course miner PSU's require between 208-240VAC. Need heap-big step-down transformer to go from 600v down to around 220V.
Having fun yet?
No need for snark. I get that watts = volts x amps, my question is more about how to go down from 600v - maybe there are some particularly efficient ways of doing so, especially since I've got to keep 20% for other purposes. It could be that maybe I should try to keep that entirely separate, in case of fluctuations. It could be that it would affect the optimal choice of miner, even, if some fluctuate more than others. Makes sense to ask this group, because presumably some people here know that stuff.
okay so 600 x 400 = 240,000 while you think 20% goes elsewhere I will use 25% trust me on this
so 240,000 x .75 = 180,000 'free' to mine
derate by 20% = 180,000 x .80 = 144,000
since an s-9 miner uses about 1440
144,000/1440 = 100 s-9's
now here is the funny part the guy you called snarky has really good links for big step down transformers
I don't know off hand where to find them.
Since you are going to be running a large operation I could research it for a fee .
send me a pm.
I know of one company that makes a 600 volt to 208/120 volt up to 15 kwatts you could buy a few to see it you like them.
they lose about 3% so a 15kwatt is about 14500 watts enough for 8 s-9's once you derate 20% for safety sake about 1100 usd
found a second company for you has a big model will do the whole load with overhead for 10k can do 225kwatts
600 volts in 208/120 volts out
shipping is costly as it weighs 1 ton (well 1925 lbs)
personally I would order the smaller ones and have multiple circuits. if one breaks it is 1100 plus ship to replace and your others are still working.
