Two of the circuits will be a 3-wire, multi-wire branch circuit (Edison 3-wire). The location of the devices is to be determined by the student. The student shall be responsible for selecting the correct circuits, do not ask the instructor which circuit number should be used.
Circuit A. One lampholder and one duplex receptacle controlled by a Single Pole Switch.
Circuit B. Single Pole Switch controlling the top half of a duplex receptacle that when energized, is indicated by a Pilot-light at the Single Pole Switch location; plus an Isolated Ground Duplex Receptacle that is always hot.
Circuit C. The bottom half of the switched receptacle on Circuit ‘B’ is to be always hot; plus another Duplex Receptacle that is controlled from two locations using a Coast 3-Way wiring-system.
