A typical US household circuit is 15 amps. At 120 volts, that’s 1800 watts. You’ll also see some 20 amp circuits, but that’s still just 2400 watts. You’d have to go to the heavy appliance circuits to draw more than that.
I wouldn’t be surprised if the 240V circuits that some countries use can probably squeeze more on; might be aimed at that.
In the UK, the standard household current is typically supplied at 230 volts with a frequency of 50 Hz. The circuit breakers in most homes are usually rated for 16 amps for general-purpose circuits, such as lighting and power outlets.
That’d be 3680W. So you could run it on a typical household circuit in the UK, though it’d eat up a lot of the circuit’s capacity.
EDIT: I mean, I assume that realistically, this is for datacenters trying to optimize compute cost, buy fewer PCs to run more compute cards in parallel, so they probably aren’t going have as much of a problem with it.
Also, if they keep ramping up how much heat they’re putting out per unit of space, I don’t know whether existing datacenters are going to be able to handle the cooling.
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.
At least here in Finland having each room behind a separate, or sometimes multiple, 240v 16A breaker is fairly common and has been for quite a while.
E.g our living room has four in total - outlets on the opposite walls are two 16A circuits, the electric heaters on a third, and lights on a 10A one. The main breaker is 3x35A three-phase IIRC.
Yeah, I was gonna say.
