How much power is Neptune slated to pull?  Is it beyond anything a typical US household/apartment AC outlet could feed?
I think it will be like this:
If you connect the Neptune  to it's OWN 20amp circuit, with nothing else, you should be fine.
Whatever you do, don't put it on the same circuit as something like a microwave, or toaster, or anything that draws significant wattage. Make sure it's on a 20amp breaker minimum.

When you estimate a 20A circuit, you mean on a 110V line, yes? European 230V @ 16A would give 3680W, which should probably hold if kendog77's estimate of 3000W power draw is anywhere near what we will get.
I really hope that it will draw less than 3000W to be able to have it along other things on a slightly loaded circuit.
Assuming it will be powered by ATX PSUs, the max spec for North America would be 1300W per PSU. Yes, there are 1500W supplies, but 120V/15A circuits must (electrical code) be derated by 20% for continuous use. So 120V x 15A x 80% is 1440W at the wall. A 90% efficient PSU supplying 1300W DC would be right at the limit. If we use 2 of these, we can supply 2600W DC at most.

So drawing less than 2600W DC would be ideal. Otherwise North American people without convenient access to 240V lines would be ... inconvenienced. Sad

I myself would have to find a 240V line to run that machine unless i can get two 1500W PSUs to run it. Even then i am going to have a huge issue with my power being in an apartment


my question is can you run two of these off a 100 amp panel? (er legally code wise I mean)...I have no central a/c and a boiler for heating so no load there just a oven and clothes dryer..( (and if the oven has to go to gas and the dryer to gas so be it)

my own guess is I'd need at least a 200 amp service to be up to code but that would suck
