DIY Wiring A Shed For Electrical | Shed Build Part 12

As I say in the video, I'm not an electrician - I recommend consulting one if you're planning to wire your shed, cabin, or tiny house, but I figured my experience and the full process I went through might be helpful or entertaining. I am running UF-B cable underground from my main panel to my 10x16 shed. I'm creating 2 circuits, one for lights and one for receptacles (outlets). I show my planning process as well as the install of my 12-2 Romex, 14-2 Romex, 14-3 Romex, and all the switches for my light fixtures.
My first outlet is GFCI to protect all the electrical inside the shed.

Thanks for sharing and posting video. Its exciting to see what others are doing! I do have some feedback…
1- Wrong glue
2- Get in practice of “walking the dog”, roll your wires out so they are flat. Makes neater installation.
3- Need better staking of the wires.
4- Some of the wire seems close to edge. Wire protectors are cheap.
5- Assuming that's a square D 2-circuit, two space load center, its rating of 30 amps allows you to have 2 single pole breakers up to 30amps each or 1 double pole up to 30 amps. You can feed both lugs from the feeder line but keep in mind you can't double tap on main lug.
5- So, you added a second box so you can run #14 wires for lights? Seems complicated.
6- Your thinking is your 20 amp breaker in shed will trip on overload before 20 amp in other structure. Probably not.
7- You said you are feeding this from your garden shed. That would mean you have a sub panel in there and the structure has grounding rod or rods, right?
8- you are leaving yourself open for future second circuit? Typically an outbuilding can only have one feed. That can feed a sub panel. I believe there are some provisions for a second circuit if its lights and that is controlled by the main structure.
9- There are other pvc conduit fittings that provide the access 90 degrees of what you have. That way, in your installation, its not against the structure.
10- your second load center box. You didn't ground it?
11- The breaker protects the circuit. Your statement of I can't get 35 amps made no sense. Of course you can, doesn't matter where the breakers are you wont be able to draw more than the max the circuit protection is rated for… 20 amps on your feedline.
12- why installing a gfci. It must be redundant if you are pulling from another circuit that must have gfci protection. Nothing wrong doing so as long as you keep your line and loads straight. But why add it if it doesn't do anything.
13- your feedwire from loadcenter box A to B - consider putting in conduit between or have wire properly staked.
14- the grounds in the first load center connection looks sketchy.
15- nice job on trench and the warning tape.
16- I would have added another 90 degree conduit body where you exited the wood instead of the long 90. Less tripping hazard.

Careful when you get into grounding of outbuildings, consider when ground electrodes are required, always keep in mind that neutral and ground only come together at the main service.

Excellent video dude! I wired my shed about two years ago but am thinking I’ll go back and make some upgrades based on your video here. Thanks, keep up the great work.

Electrician here. Normally 95 percent of these electrical videos are so hard to watch with how many mistakes are made, but I think you did a great job. I saw that you were strapping your wire at the end of the video. Just make sure your wire is strapped within 8 inches of every enclosure, Including the disconnects, and that your pvc is strapped within 3 feet of every box. Only other thing I'd comment on is doing neat work but this looks good still. Nice job!

This answered a few big questions I've had concerning a project similar to what you did and I Ty for putting out a video that I could relate to and learn from. Good work!

[paulrnash]

That glue you used is for CPVC… never seen that done on conduit before. There’s a gray glue in the electrical aisle that is what usually is used.

Great stuff, I recommend you get a wireless mic, like the Rode wireless 2 or the new DJI wireless mics

[danielrobertson]

So you had an existing 20 amp circuit running to your garden shed. You tied into that and ran a 12-3 line to the new shed and attached a new 20 amp breaker and a 15 amp breaker. By my math you're now running 55 amps of service off that original 20 amps going to the garden shed. 
That original breaker going to the garden shed is now very underrated, and the original wiring is undersized.
What am I missing?

Why do you need a breaker inside shed when you have one inside house

[enricoagnoli]

I have a 15Amp breaker from the house and a cable getting from that to the shed. I was thinking to run 15Amp to the plugs. Is it too low?

How much did you end up spending on this build?

Can we get a ridgeline update? Any new mods?
