There are two phase wires and one neutral. Diff between phases is 240V, the diff between any phase and neutral is 120V.

In Europe, you have three phases (R,S,T) and neutral. Here the diff between any phase and neutral is 250V, and the diff between any two phases is 380V.

In Europe, you have three phases (R,S,T) and neutral.

Is that everywhere, to every building?

In the USA, of necessity, power generation is three phase, large scale power distribution is three phase. What's confusing is that the previous discussion didn't differentiate between residential and commercial.

In USA residential areas nobody gets all three phases to their house or apartment. As discussed in previous comments, a house gets two hot wires and a neutral. In fact, to save money, sometimes entire neighborhoods only get one or two phases[1]: "spur lines" branching off the main line to provide power to side streets often carry only one or two phase wires, plus the neutral

In commercial and industrial settings it's common and necessary to deliver all three phases to the building. E.g. large electric motors require all three phases.

Unless you are in a really remote place you have three phases. Yes. Our stoves are typically connected to it (obviously not to all phases at once).
