You guys in the USA have pretty low rated installations.
This is why we hate 120V 
I could of easily run 240V (double-pole) 30A circuits from my breaker but instead I did the equivalent of three 120V (single-pole) 20A circuits that a single 240V 30A circuit would of handled with the same gauge wiring. -- I basically put in nine 120V 20A circuits in the end in which I could of just done three 240V 30A circuits. For a total of 21.6kW-rated, or 17.28kW @ 80% capacity. (Homes in my area have 200A service).
We get 240V delivered to our homes in the U.S., but U.S. consumer products requiring power are generally 120V. Generally only large appliances in the U.S. (e.g. clothes dryers) run off 240V.
I was going to run all the mining rig's PSU's at 240V, but decided against it knowing the sooner or later, unless I change the outlet type to something other than standard NEMA 5-15P, I'd end up plugging in a 120V-only device into 240V and instantly fry it... Ended up being more cost effective to just buy the extra Romex and 20A breakers at $2.96 USD a piece then changing out all the AC plugs to 240V plugs.
