mains
This term refers to the primary infrastructure of utility distribution, whether electrical or hydraulic. It carries a technical yet everyday connotation, typically used when discussing home utilities or municipal infrastructure. In British English, it is the standard term for the domestic electricity supply, whereas American English more frequently uses "the main" or "the power grid."
Grammatically, this noun is a plurale tantum, meaning it is used exclusively in the plural form to describe a single system. It does not have a singular counterpart in this context; one does not refer to a "main" when discussing the general electricity supply of a house.
