I found myself in need to move my noisy woodworking to my back yard to avoid waking up my lady who works night shift. I decided to wire my shed and after some homework and the help of the Instructables community I started my project. Before we start I assume that you know how to wire the different fixtures.
First you will need:
- Liquid tight conduit or direct burial electrical cable
- Electrical wire (12-2)
- Switch box
- Switches, electrical outlets, light fixtures
Step 1: The right conduit
I bought 50 feet of conduit, more than the distance between my house and my shed. The conduit will be connected to a switch box in my basement and to a junction box inside my shed.
You will need an electrician's fish tape to pull the wire inside the conduit. If you find difficult to pull the wire there is a clear lubricant that you can use to make the job easier. Make sure that the lubricant dries before you connect the wire to the main box.
Step 2: Wire
I became aware that it is against electrical codes to use sheathed cable inside a conduit. Therefore you need to pull three unsheathed wires inside the conduit with a fish tape.
- Black wire for the "hot" or "live wire"
- White wire for the neutral
- Green or uninsulated wire for ground
Step 3: Switch box
One end of your conduit will be connected to this box. When all the wiring is safely installed you can wire the switch to your home electrical panel.
Step 4: Digging the trench
I found a large rock while digging and I did not have any dynamite to blast it so, I patiently dug around it.
Step 5: Wiring the shed
I drilled pocket joints in two pieces of 2 x 4 and screwed them to the supporting studs. Then I screwed a 3/4 inch board on the 2 x 4 's.
