Wiring make up of a power supply to light to switch?
Question:I have a power supply to my utility shed and now I am adding a light and a switch. How do I make the tie ends to the light and then down to the switch.
Answers:
First, make sure you have a hot(black), a neutral(white) and a ground(green) wire in your cable. If your just adding a light, 14/2 cable will be sufficient. Most typical installations have the wire hitting the switch and then going to the light. Run the incoming cable to your switch location. Break the cable there, leaving about 12" worth of cable to play with and run a length to your light location. At your switch location, connect the black wire of your incoming cable to a brass-colored screw on the switch. Let the ground wire and neutral wire hang loose for now. On your light-leg portion of the cable run, take the black wire and connect it to the other brass colored screw on the switch. Using wirenuts and a scrap piece of wire, connect all ends of the ground wires together and connect the "pigtail" (scrap piece of wire) to the ground screw on the switch. Using wirenuts again, splice together the neutral wires. No pigtail for the neutrals is needed.
The connections to the light should be fairly straight forward. If the light has black and white wires, connect same colored wires together. If it just has screw terminals, coonect the black to a brass screw and the white to a silver screw and the ground to the ground screw on the fixture (usually colored green).
Hope this helps!!
first you have to make sure that you have, 120 volts in the first box that feed your shed.
open the box of connection of your shed then run another wire number 14/2 of 12/2.one from the shed to the switch. and another one from the switch to the light.in those wire you should have 3 wire one black one white and one green.
the green wire is the ground.
the white wire is neutral . and the black wire is the hot wire.
ok now the connections.
the white wire have to be together I mean the connections.
the green wires have to be together.
and one of the black wire that is caming from the shed is going to one of the screws in the switch.
the other black wire that is going to the light is going in the other screw of the swich. in the light you should have 3 wire green white and black. good luck
