How to make a junction box -- wire splicing

You need a staple for the cable regardless of the type of box knockouts. And the distance is 8" for a plastic box and 12" for a metal box.

Great job at explaining "how to do a junction box"! I appreciated how you came back and added those important details. Well done!

This video was super helpful for me. Especially the section beginning at the 3:38 mark about installing 2 junction boxes when there's no slack!

This is the universe's way to remind me to do this. My random splice of wires hanging out in the open has been bothering me lol. Nice video

I’ve watched over the last few months hundreds of these videos and yours is by far the best & easiest to understand. Some guys, & I’m sure they know what they r doing, don’t explain things very well & it’s hard to understand if ur not an electrician. Thanks for ur help, I really appreciate it.

I really appreciate the updates and overlays. Thanks Dave! If you had run this as scripted and shot, it was a pretty average video, but your care taken to fix words you misspoke, safety features that were glossed over, and even stuff that was entirely forgotten makes it almost a perfect junction box video, from my perspective. It's even better than if you somehow wrote and produced it perfectly the first time, because it calls attention to critical and easily-forgotten issues! Keep making "mistakes" like this!

In Oregon I was a laborer on a housing addition. I happened to be alone on site when the electrical inspector came. He looked in the attic and saw romex lay over the top of the ceiling joists and said he was going to fail the inspection due to that. I asked him what he wanted to see to take care of that problem. He said a 2x4 along side of the wires would suffice. When the contractor came back to the site, I relayed that information and rather than calling for the electrification to come back.he had me put in the 2xs and called for another inspection. Which passed.

Dude, thank you so much! This is by far one of the greatest tutorial videos on YouTube. Thank you!

Make sure to test your non contact probe on a known live circuit to make sure it is functioning correctly.

Great job Dave. I was trying to figure this out using just one box, this is far easier and safer than my thought. Knew there was a better & easier way. Gotta love YouTube. Thanks.

I found this video really clear and helpful! I was not able to get this clarity from Home Depot.

I put a new circuit for an inline 10" booster fan in my attic to help get extra A/C air volume to the furthest part of my house. It worked great, but I have another room that needs a boost so I'm adding another fan. I was going to tap into the wire I ran before but there wasn't enough slack to do it with one junction box. I didn't even think about using 2 junction boxes until I watched this video. I was stalled because I was over thinking how to do it to properly to code. This video made me say 💡💡💡"Oh DUH" because every other circuit has numerous junction boxes and splices for all the outlets and lights. Using two junction boxes this close together is quite literally no different. 😅 So thank you kind man, for this video.

It's one of the best videos on utube.. You explain you show you do all at the same time...youre a good teacher. THANK YOU SIR😊

Just what I needed, thank you. I'm replacing some sketchy wiring that was spliced on without a junction box or wire nuts

Dave, thank-you. This is a huge help for us that aren’t electricians. There’s always going to be a critic that is somehow offended by the helpful. Nobody likes them anyway. Great presentation!

Thanks for the video(s) and the clarifications on this new one.... much appreciated.

Very, VERY helpful. Thank you!

Thanks for sharing. Great video. Well explained and simple. Thanks so much. You just saved me $200.00 . An electrician was going going to charge me $200.00 for doing this for me.

Thank you for such a detailed video, going to be extending wires and running an additional outlet off a constant power line. This is very informative!

Thank very much for your helpful support!
