A motor branch circuit, or motor branch, is a circuit that provides power and protection for a motor. According to the National Electrical Code® (NEC®), a motor branch must have a means to disconnect the entire branch from its power supply and a means to protect the branch components from the potentially damaging effects of excessive current. How a motor branch functions and how the necessary protection is provided are the subjects of this course.
