120V is only standard in a part of the world. It's much more helpful to talk about power -- where I am 3 kW is limiting on a standard socket, at 230V. What is it for the US (I don't know!)

Note -- electric hobs and ovens are often wired into far far chunkier circuits and the high efficiency of induction is a big boon. It's wonderful to cook on -- all the responsiveness of gas, none of the pm2.5. It's just a shame that per kWh, electricity is a lot more expensive.
