I wanted to share this simple 120v electric box wiring diagram with you, encase you ever have this need for power source.
This tractor shed is open on one side and we also use it for indoor chicken coop and barn cat palace…lol. There is no need whatsoever for 240v service here, so I have a single 6-2 120v wire running to this inside of this shed.
From a junction box right inside this shed outer wall I ran 10-2 over to the sub panel, which is a 4 lug box that can accommodate 4 breakers. Hindsight, I should have just ran 2-120v lines over instead of one, but after doing this the way I did it was cheaper and works perfect. And, it’s 100% safe and legal. I already had everything needed for this project already here from other projects, so that is another reason I’ve done it this way.
Doing it the way I’ve done it you will only have 2 of the 4 lugs hot, unless you run the jumper wire like I’ve done. The jumper wire will allow you to have all 4 hot lugs for the use of 4 breakers instead of just 2.
I also added a separate ground bus bar to make it safer and legal. I ran an additional case ground and copper ground rod that is drove into the ground 3′ deep, and copper wire from ground rod into box bus bar.
I am currently using 2 of the 4 breakers with a few more receptacles to install, and more lights to install. Currently I have 1 breaker running the water tank heaters and another running the lights. Once I’m finished with this simple, but time consuming project, I will add a walk around video to this page.
Run black wires from lights, or receptacles, or whatever you are hooking up to bottom of breakers, whites to bar above breakers, and grounds to separate ground bus bar like in the picture above here. NOTICE: The black main HOT wires coming into box runs to big lug to right of the breakers (like pictured) and then run a black jumper over to big lug on top left like pictured. Some boxes will be different, but most are very similar. The separate ground bus bar will be by itself and grounded right to the metal case. In my box I had to add a separate ground bar because mine didn’t have one. Black is HOT, White is COMMON, and stripped/bare copper wire is GROUND. If using stranded wire, then most of the time the ground will be green.
This is a simple 120v electric box wiring diagram, and wiring project that is fairly inexpensive and can be done by anyone with some electrical wiring knowledge. Other option is to hire an electrician and pay big bucks for nearly the same results.
Leave comments below if you have any questions, or would like certain pictures of anything I’ve mentioned.
Always do your best,
