> I was wondering where you'd get that from, and then I remembered that you're probably american so your baseline is only 1800W, in which case..

In North America, you cant pull 1800W continuous either, it is limited to 1440 by regulation.

"This regulation is called the maximum continuous load, which is 80% of the total wattage computed. "

This is why space heaters and such are 1200 watt.

So while 120v * 15A is 1,800W no electrician would wire a setup like this.

if you need 1800W they would use probably use a 20A circuit and wiring rated for 20A. 80% load of this would be 1920W.

NOTE: Not an electrician.. if i am mistaken please let me know.
