I believe the 277v is common for built in fluorescent lighting in
offices. (might be 3 phase?). Houses and therefore most things that plug
into a socket are either 120v or 240v.
277v is the phase to neutral voltage in a 277/480v 3 phase system - most
common in the USA in commercial/industrial systems. Other common systems
are 120/240v single phase and 120/208v 3 phase.
