So tops for a US domestic circuit is about 1500W.
How do they manage an electric kettle? No wonder we hear a lot about plugging into a cooker circuit. Those are 30A here so you could presumably light a house.
From the outside.
The usual 'max' wattage devices that are in the typical US home run about 1K to 1.5K for things like 'space heater', 'Toaster' or counter top 'cooker' type devices.
For fixed equipment, there is 220V available and those are run from the power box to the appliance. Washer/Driers/Stove (unless a 'gas' stove...), and house heating if electrical and airconditioning if installed.
There is a wall plug indicator for residential power, which indicates whether the power is a 15 Amp or a 20 Amp circuit. For 'office' use for the modern era, those are mostly 20 Amp circuits.
Old residences tend to be 15 Amp, and because of the age, one may have fire potential, so it behooves one to check out the wiring if one is location shooting and not bringing in one's own power generator.
