For a 277V lighting circuit, you typically need three wires: a hot wire, a neutral wire, and a ground wire. The hot wire carries the 277 volts, the neutral wire provides a return path, and the ground wire is for safety. This setup is common in commercial and industrial lighting systems where 277V is derived from a 480/277V three-phase system.
