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.

Thank you for pointing that out. 👍🏻 I am pinning this comment.

Its 12" no matter what kind of box it is if you're using romex. Code also does not specify whether its 12" of cable from box to staple so you can actually have a little slack, the staple just has to be 12" or less from the point where the wire enters the box. In reality you should definitely have the staple about 6-8" away, the code just provides the minimum requirement.

Second time watching this wonderful video. After the first time watching, I started making my own junction boxes in my attics, probably more than necessary lol. But seriously, this has helped me and saved my life several times when I cut NM cables with no slack to tap power. What I love about your method of installing two boxes is that they can be placed far apart, like from one side to the opposite side which is what I prefer to do for various reasons. Also I highly recommend lever nuts like WAGOs since they are perfect for this application. It makes this job faster and easier, while still providing reliable and future power. Don't get me wrong, I still use wire nuts and have no issues joining solid with stranded, but there's literally no denying how simple it is to add, remove, relocate, or replace anything inside the box, including the box itself, using lever nuts. Do keep in mind for anyone out there that once you get your hands on a couple, there's no going back; instead you'll be craving more lol

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.

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.

In 1963 I was taking a class in a technical high school that was called "Terminal Electric"" where we were taught house wiring. We didn't have wire nuts. We twisted the wire and wrapped them first with rubber tape and then with friction tape. It was years later that I started using wire nuts. It just makes sense to twist the wire. That is the electrical connection the wire nut is insulation for the splice.

Push connectors are easier. There is some debate as to reliability and safety, since the contact are basically touching the wire in a small area. The latest are “Wago lever nuts” which have a handle you push down to make a clamping connection. These cost a bit more, but many electricians think they’re worth it.

There is a power outlet in the ceiling already for the garage opener. My plan was to splice power from that source and run the Romex to a new dimmer switch. From that switch I would run another Romex line to the LED lights to power them and control them on a dimmer. Would that work? Any red flags in that plan? Any advice would be super helpful. Thanks, Dave!

@FamilyFriendlyDIY 2 жыл бұрын

Garage door openers don't require dedicated circuits, so I don't see any flags there, Brandon, and since LEDs draw very little power, I wouldn't imagine you'd be overloading the circuit. Just make sure the gauge of your Romex is sufficient for your breaker. (At least 12 AWG for 20 Amp breaker, and at least 14 AWG for 15 Amp breaker.) All the best on your project!

Fantastic video. This is exactly the two example I needed and you made it so clean and easy to understand. Your additional comments and tips were spot on and again taught me a great deal. Thank you! The only follow up question I can think of is accessibilty. You mentioned it, but what does that mean exactly. What if a junction is being added between floors before a ceiling is added or in a wall before the drywall is added? Would an opening have to be left in the ceiling or wall board with a face plate for future access? I am guessing so, but if you could expand on this, that would be great.

@FamilyFriendlyDIY Жыл бұрын

Thanks! There are "repair" electrical couplings that can be hidden in walls (I have another controversial video out there on those), but in general, if the connection is for an add-on and not a repair, you have to be able open it up. Some people just use a blank cover (usually metal) and paint it the color of the ceiling or wall. If it's in the floor, I would buy a floor receptacle and cover and wire it so that it would be both a junction box and outlet. Here's the video on the connectors ... but they're getting hard to find: kzfaq.info/get/bejne/aqemiamFx8Xbm5c.html

So although I know the metal boxes are stronger, I don’t see how it matters other than weird edge cases.

@boeing757pilot 8 ай бұрын

Good job. But let me add a few suggestions. Here, the junction boxes are mounted on the horizontal members (ceiling joists). The problem is that someone later blows in insulation (and buries them). The boxes will never be found should they need to be accessed. I suggest you mount the boxes on the vertical members about 12 inches or more above the ceiling joints so that they remain visible. Also, grab a sharpie and write "bedroom" (or whatever) across the cover to distinguish it from other junctions. Much easier to troubleshoot. Finally, these boxes are fine. But if you drop those cover screws in the insulation, youll never find them. I suggest you use a 4x4 box that allows the cover to be removed by loosening the screws, not removing them.completely. In the end, thanks for a well done video!

I have this exact situation in my attic. Perhaps someone ran a wire up from the panel in the basement and came out a few feet short and had to extend it rather than redo a long run. The junction box is a 4x4x1.5" metal junction box with a bracket that is screwed to a beam. However it must be properly grounded with a pigtail and a green grounding screw to avoid a shock hazard. An added advantage is that you can add a cover plate with a duplex receptacle for plugging in lights or power tools.

Breakers don't actually trip at 80% load. The code dictates that you shouldn't apply more than 80% load on a circuit (just to be safe). But even if you do go over the 100% rated load it can take many minutes or even hours for a breaker to trip.
