Wiring 2 Receptacles, 1 Light Switch and a Light in a Shed
December 9, 2007
I have a cabin and I want to run some wire to my shed. In the shed I will have 2 receptacles and a light that is controlled by a switch. The question I have is where should the circuit start….at the switch, or the light or at a receptacle.
It doesn’t matter where you start the circuit. You may start it where ever it is easiest for you. If it were me, I would probably start the circuit at the light switch. From the switch install a cable over to the first receptacle. You also need to run switched power from the light switch up to the light. Finally, install a cable from the first receptacle over to the second receptacle.
Terminations in the switch box:
1. Connect all ground wires together and leave an approximate 6 inch tail to connect to the ground screw on the switch.
2. Connect all of the neutrals together, place a wire nut on them and fold them into the switch box.
3. Connect the 2 power wires together (power in and power out to the first receptacle) with an approximate 6 inch tail to connect to your switch. Place a wire nut on these wires and fold them into the switch box.
4. Connect the ground wire to the ground screw on the switch.
5. Connect the switched wire (to the light) to one terminal on the switch (either terminal, it doesn’t matter)
6. Connect the tail from the power wires to the other terminal on the switch.
Terminations at the first receptacle:
You are required to use a GFCI receptacle here.
1. Connect all ground wires together and leave an approximate 6 inch tail to connect to the ground screw on the receptacle.
2. Connect the neutral wire from the power in cable (from the switch) to the line side neutral terminal on the receptacle.
3. Connect the hot wire from the power in cable (from the switch) to the line side hot terminal on the receptacle.
4. Connect the neutral wire from the power out cable (to the second receptacle) to the load side neutral terminal on the receptacle.
5. Connect the hot wire from the power out cable (to the second receptacle) to the load side hot terminal on the receptacle.
I’m assuming that because there is only 1 cable at the light and second receptacle, the terminations are straight forward.
Since the shed is not heated, I recommend an incandescent light. These work much better in the cold. You may try a fluorescent light, but they do not like to start when the temperature in below zero; unless you get a specialty (high output with a cold weather ballast) fixture.
