A split-wired receptacle is occasionally referred to as half-hot.

Quick scoop

  • In a split-wired (split) receptacle, one outlet is controlled by a wall switch and the other remains constantly energized.
  • Because only one “half” of the duplex is switch-controlled (hot from the switch) while the other is always hot, it is commonly called a half‑hot receptacle.
  • This terminology shows up frequently in residential wiring training materials and exam-style questions, where “half‑hot” is given as the standard answer for this description.
