They are 240 V center-tap grounded. That is what is provisioned to most
residences in the USA, usually from a single-phase transformer on a pole
(or on a pad if distribution is underground). 120 V branch circuits are
distributed equally between the two 120 V lines in the breaker panel.
Electricians incorrectly refer two the two 120 V lines as phases and the
grounded conductor as the neutral.
Three phase is perfectly legal if you are willing to pay for it,
though.
