How to Wire a Single Phase Stop-Start

Rube Goldberg was famous for his cartoons of complex machinery used to complete a simple task. He would have loved the single-phase stop-start switch, with its two separate buttons: One to start the activity to which it's wired and one to stop it, like a heavy duty light switch. A single-phase switch may turn on a simple, single-phase motor -- or trigger the two- or three-phase breakers that operate a complex machine that uses hydraulic rams, a Ferris wheel and a coconut to pour a glass of milk.

Instructions

    • 1

      Open all circuit breakers related to the circuit on which you plan to install the switch. Use a padlock to secure the breaker in an open position, if possible. Tape a note over the breaker explaining that the breaker must not be closed.

    • 2

      Strip the ends of the wires to be connected, using a wire stripper. Crimp ring terminals over the stripped ends of the wires, using a wire crimper.

    • 3

      Hold the stop-start switch so that the "Start" button is at the top of the switch. Inspect the screws on either side of the "Start" button, one marked "L1" and the other "L2." Remove both of these screws, using a screwdriver.

    • 4

      Insert one of the screws through the ring terminal of the power wire -- usually red -- of the circuit on which you are installing the switch. Thread this screw into the "L1" bore and tighten snugly.

    • 5

      Install the ring terminal of the neutral wire -- usually brown or white -- over the second screw you removed. Thread this screw into the "L2" bore. Tighten the screw securely, using an insulated screwdriver.

    • 6

      Set a digital multimeter to test for circuit continuity. Place one of the multimeter's probes on the head of the "L1" screw and the other probe on the "L2" screw. Push the stop-start switch's "On" or "Start" button. The multimeter should indicate continuity. Push the "Off" or "Stop" button on the switch. The multimeter should indicate no continuity.
