L3+ are almost totally enclosed, but I'm pretty sure they still would fall under the Business-class FCC EM radiation rules (which are less stringent than the home rules).

Look up "Faraday shield" sometime.

As far as power to a warehouse - 3 phase normally doesn't get used 'till you're quite a bit over 100 kw - I think the SMALLEST 3-phase service I've ever seen was 480v 300 amp (which works out to be over 140kw PER PHASE and over 400kw total service) though I have vague recollection of a co-worker talking about a 200 amp 3-phase setup he helped install MANY years ago.

Cooling is going to be an issue - even a big CENTRAL A/C isn't going to keep that many miners cool.

Central A/C is usually rated in "tons" for historical reasons (appx. heat value one ton of ice melting is the origin of the term) - a "ton" is 6000 BTU/hour, 2000 watts generates a bit MORE than 6000 BTU/hour and it's rare for a HOME central A/C to be rated much more than 6 tons - or about the heat generation of 12 KW which is somewhat less than 10 S9 units use.

Most folks either use lots of airflow and tolerate running their miners at ambient temp or a bit more, or use lots of airflow with evap cooling (which DOES work fairly well in some parts of Texas).

Great info, thanks !
I'm defintly getting a warehouse. Its much much bigger than i need but will have room to expand. It comes with 460amp 3-phase power so i should be good to go.
