Form a c shaped loop in one end of the black wires and hook it in a clockwise direction around the bottom screw terminal on the side of the switch. With this wiring configuration you would end up with 3 black wires.
Light Two Lights One Switch Wiring Diagram
How do i wire two lights to one switch. The most common is to daisy chain the light fixtures by connecting them to each other and hooking the first one up to the switch. Two wire cable runs from the combo to the light fixture and the switch output is connected to the black wire running to the fixture hot terminal. Slice open a spare length of cable that is 6 inches long with a utility knife and remove the black and bare wires. Connect the black wire from the light fixture and the black wire from the second switch with a wire nut. Run your cable from the first light to the second light. Tighten the screw firmly.
Community answer connect the one black wire to the bottom dark screw of the other already wire configured switch. To wire this circuit in this manner you will need to run a 143 between the two light boxes. Connect the black wire from the switch to the black wire from the first light and the black wire coming from the second light. It is one black wire from the power source hot wire and a black wire from the neighboring switch. One black wire for the switch as the power source. The source neutral wire is spliced to the neutral on the receptacle half of the combo device and to the white cable wire running to the light.
You can do this light switch wiring in one of two ways. Wrap a piece of black electrical tape around each end of this white wire to indicate that it is a hot wire rather than a neutral wire. The other way to wire multiple lights to one switch is to connect all of them directly to the switch in a home run configuration. Essentially 2 black wires are attached to the bottom dark screw of one switch. Strip about 34 inch of insulation from one end of each black wire. At the light it connects to the neutral terminal.
This will allow you to connect the first light as you described above and to run this additional light from the same switch by utilizing the red conductor in the 3 wire as the switched conductor and the black wire as the continuous hot wire. Remove 12 inch of insulation from both ends of the black wire. Step 16 connect the bare copper ground wire from the circuit power source to the green grounding wire of the light fixture with a wire nut. Cut two lengths of black wire and two lengths of bare copper wire about 6 inches long. The most common wiring connections for two outdoor light fixture the black wires going to the motion light fixtures need to join together but not on the switch instead splice the two wires after the switch.
