Further, US national electric code states that a continuous load (3+ hours) is de-rated to 80% ampacity, so we're looking closer to 1400W.
The solution if you really need that much wattage in the US is to use a 240V circuit, dual pole 20A breakers are commonly available, Romex yellow is fine for 240V@20A, just gotta get a NEMA 6-20 outlet.
Alternative roots are an interesting concept, but really people just need good alternatives recursives.
