Wire A Single Pole Switch To Control 3 Lights

Even though the term "single pole switch" sounds as if it's meant to control one light fixture, the device can control several fixtures. Wiring a single pole switch is not a difficult task, and it's one that most homeowners can perform safely when they follow the proper directions.


Instructions


1. Turn off the power to the circuit. Map the locations of the three fixtures in the room, as well as the wall switch.


2. Hold each mounting box up against the ceiling and trace it with a pencil at each of the three locations. Do the same thing with the wall box at the location of the switch. This is necessary if the room is already finished with drywall.


3. Using the drywall saw, cut away the access holes for the fixtures and the switch.


4. Using the NM fish, run the NM cable from the switch to the first fixture. Then run another length of cable from the first to the second and from the second to the third fixture. When you are finished, Fixtures 1 and 2 will have two lengths of NM cable in their location and Fixture 3 will have only one.


5. Install the fixture brackets in each of the three locations. Pull the wires into the mounting boxes and connect the boxes to the brackets.


6. Use the Romex stripper to remove the outer sheath from the cable in the ceiling boxes. Use the wire strippers to remove about 3/4 inch of insulation from the ends of each insulated wire.


7. Take Fixture 3 and make the following connections:


Connect the black fixture wire to the black ceiling wire.


Connect the white fixture wire to the white ceiling wire.


Connect the ground ceiling wire to either the fixture's ground wire or the ground screw.


Wrap each connection with electrical tape and mount the fixture to the ceiling box.


8. Take Fixture 2 and make the following connections:


Connect both black ceiling wires to the black fixture wire.


Connect both white ceiling wires to the white fixture wire.


Connect both ceiling ground wires to the fixture's ground wire or make a pigtail and connect it to the ground screw.


9. Take Fixture 1 and make the same connections as described in Step 8.


10. Take the single pole switch and make the following connections:


Connect both white wires together in the box.


Make a pigtail with the two grounds and connect it to the ground screw on the single pole switch.


Connect the black wire that's going to Fixture 1 to the top screw terminal on the switch.


Connect the black feed wire coming from the panel to the bottom screw on the switch.


Wrap the switch terminals with electrical tape and secure this to the wall box.


11. Screw on the switch cover plate. Install the lightbulbs and fixture covers.


12. Turn on the power to the circuit. Test your installation by toggling the switch on.
