[@EngineerMikeF]

The little "insulation piercing" terminals are used in box fixtures designed for RV's, and they work even they work. Usually on close inspection you'll find a thin bit of insulation jammed into the vee with the conductor, so the contact is lousy. U can improve that nicely by stripping a window on one side or both of the conductor before seating into the vee; this eliminates the thin insulation from melting when the connection gets hot or the compressed insulation pushing the conductor back out of the vee, both of which are common failures.

[@davyc444]

@@cryengine_x I'm not an electrician and Ive never used or seen one of these before today. However I do agree with the above commenter and here's why; The contact being made with the conductor is extremely low. Look at the bite mark in the insulation when he crimps the 14 gauge wires into it. The amount of contact is exceptionally low and you have a total of 4 of those weak connections in a single circuit using one of these. Using 12 guage wire like in the actual ceiling install in the second part will likely give a significantly better connection however, now instead of having to support a 15 amp circuit, you're now asking for it to handle 20 amperes. If even one of those connections is weak it's a problem but remember, there's four. There's too many potential points of failure to be worth it. Now if they made something similar to this but with a beefier strain relief and a connector that made more contact that actually involved stripping the wire back like a wago connector I'd be in and say "cool, use it if you want". If you absolutely HAVE to use this device for whatever reason, please, please, PLEASE use it in combination with a combination AFCI breaker so if the connection ever breaks down and it starts arcing, it'll hopefully trip the breaker at least. It would also be best if this were only used on lighting circuits only that will never see more than 5-6 amps pulled through them. Running 2500w through this thing is just asking for trouble

From my understanding from that video these connectors are a 1 time use and if they were to ever fail or be taken apart for any reason they would need to be replaced with a new one. Now I understand why you don't have to strip the insulation back for the clip to make a connection Was unaware that the clip made its own connect via biting through the insulation to the wire.

I live in the midwest and everything here is in metal conduit, so we do not use romex but use solid insulated wire for homes. You cannot use anything but junction boxes for splicing, etc. You cannot cover up boxes, they must always be accessible. I have run into this a few times doing some remodeling. Our solution in ceiling or anyplace in drywall is to use a round decorative cover. They make them in white plastic or metal that you can paint if necessary. The covers I used were over octagonal metal boxes. Once installed they are inconspicuous. If I could I would include a picture. Thanks…Jim PS……I learned about these from some old electrician’s leftovers which I got at a garage sale.

Good info, Jim. Thanks for all of that.

[@rpsmith]

I'm guessing you probably live in Illinois. The reason you can't use romex and everything has to be in metal conduit is because of Unions! I think they mostly run your state!

[@jimpie231]

@@rpsmith Yes, I live in a NW suburb of Chicago. My folks lived in Charlotte, NC and they had romex. I ran into a short in their house and it caused a lot of problems. They were using a freezer in the garage and it would pop the breaker, anytime, without warning. I ended up running a separate line for the freezer, because of this problem. Eventually, I found the problem, it was a shorted out night light. The problem with romex is, if you overload a line and it gets hot, there is nothing but the jacket of the wire and the outer covering to protect you from a fire. My dad’s home in Charlotte was built in 1985. In the attic was a bundle of romex cables on top of each other going all over the house. This scared me. Here in metal conduit, you have another layer to protect you. When you run power outside it has to be 1 foot below the ground in ridgid metal conduit (thicker than the regular metal conduit), whereas in Charlotte it’s just romex, do you know how it’s protected from a shovel accidentally breaking thru? Knowing both systems, I prefer metal conduit and metal boxes. They do metal conduit everywhere, it’s a matter of choice and paying for the difference. Most businesses in Charlotte are done in metal conduit. I looked into buying a home in Myrtle Beach and the metal conduit option was there if you wanted it. Plumbing has similar options today, copper versus plastic hot and cold water lines. Plastic drainage systems are common almost everywhere. Thanks….Jim

[@rpsmith]

@@jimpie231 -- Approximately 90% of homes in the U.S. are wired with Romex and if it's installed properly it's entirely safe! And yes, some form of metal conduit is required for all business high voltage wiring throughout the U.S.. I think this post I found online from Bob Weiss mostly explains the conduit requirements in your part of the country: "Bending and installing conduit properly puts electrical work outside the skillset of the typical DIYer, creating more demand for (often unionized) professional electricians." While arguable safer, this requirement doubles or triples the cost of wiring a home in your area! Given a choice I think most new home buyers would choose Romex!

[@alphasaiyan5760]

A box can be covered up and still be accessible. Accessible and readily accessible are two different things sir. Like you can make up a box and shove it up into an attic. It’s accessible. It may not be readily accessible but it’s accessible. If this guy made up this splice and buried it in the wall that’s another thing . That’s why anytime you do any type of work whether it be electrical , plumbing , hvac , or anything you always keep records , as builts , so that you will always know where anything and everything is. You can leave notes for any future workers that may follow your work. You can leave hand written notes inside panel covers that explain what you’ve done and where things are. Doing things like that sets professional electricians apart from half assed wannabes.

[@foogod4237]

I'm with a lot of other people that even if these are accepted by code, they still seem like probably a bad idea in most situations.. The really sad thing is that it seems like they could actually be so much better, though. The real key bit here that potentially makes these ok without a junction box is (a) the metal strain-relief brackets on the two wires coming in and (b) the fully-contained wire connection points. However, both of these could be better done in other ways: Make a _single_ metal bracket that both incoming wires are run through at either end. Then use something like a double-ended Wago connector in the middle, so you actually strip the wire ends to the right length, feed them into their individual holes, and clamp them down with a simple locking lever (possibly even with an enclosing plastic box around the whole thing), and then weave them through the bracket and you're done. It would provide better strain-relief, much better electrical contact, fewer potential failure points, would almost certainly be more reliable, could probably be made smaller, would be harder to do wrong, and actually wouldn't even require a screwdriver to install. That kind of device I might actually consider using. This one? Even if it's technically to code, probably not.

[@nunya3163]

I like your idea for the metal bracket, with strain relief at each end, makes a lot of sense. And I would think that even your garden variety crimped connector would be better than this thing, as there is virtually zero connection area. I would worry about this getting hot, and melting.

I can't believe the NEC or NFPA allows this kind of "splice". Insulation-displacement connection forks should be considered temporary at best (better not at all) due to their limited electrical contact points. Also, dissimilar metals contacting each other with current passing between them is always a bad idea. The shells are very likely molded of thermoplastic (softens when heated) and the "clamps" will quickly damage the NMC if used in a vibration environment.

The one-time-use nature of these splice kits cannot be overstated. Similar to punchdown connectors and blocks for low voltage in telecom/Ethernet, these cannot create a reliable connection a second time, after disassembly and removing conductors. The first time the conductors are pushed in, the two blades of each connection point deform, enlarging the slot ever so slightly. If you haven't patched the hole yet it would be best to re-perform the splice with a new kit.

When connecting a water pump down into a well, you need to splice an electrical power source (240 volts) onto the pump which is submersed in well water. To do this, crimping devices, along with a bit of solder, are used to join the pump’s wires to the wires that run the depth of the well. Once the wires are joined, a special shrink tubing is slid over the union and heated. This special tubing, upon being heated, excretes a sealant that fills the inside of the shrink tubing which seals the splice and allows it to function under water. Now, if we can do that in as hostile an environment as a well, why can’t we do the same while splicing a wire in a house? It seems a much simpler and cheaper way to do this than the weird contraption that you are using to solve your problem.

Thanks, Joseph. Researching this, I've seen a lot of electricians on forums saying they just hide metal boxes in the walls.

I am so glad you brought this product up, as there will be that situation it will be needed. As an AHJ and Master Electrician for 34+ years. The 2020 NEC Art 334.40 Boxes and Fittings (B) Devices of insulating material. These are Non Metallic Sheath Cable Interconnector devices and are acceptable concealed in walls and ceilings for a "repair" of damaged wire and for exposed cable wiring (example -romex in an attic that is accessible). Tyco list this product as "rework". Which the NEC DOES NOT. This is the classic case of a design engineer playing with, changing, or not knowing the exact wording in the NEC. For what you did in the video. Great job. I would have passed the inspection for that product, even covered up by drywall. Granted, possible problems in the future, but acceptable be code. But.... if someone were to move a switch or move a light to start a "rework / remodel". I would fail the inspection with this device concerned as that is not a "repair" as stated in the NEC code. Then this item must be accessible or start installing splice boxes.

I have a junction box in my bedroom with a blank plate on it. I spliced it myself using wire nuts. I feel safe knowing it's spliced using something that is mechanically and electrically connected with substantially more surface area connecting each other than a wago, or an insulation piercing contact. I don't understand why people do things like this. The NEC or the CEC where I'm at is the law and it's your duty as an electrician to follow that law.

[@foogod4237]

@@alexvega8026 Agreed. I'm not really any kind of Wago evangelist in particular, but if one actually does look this stuff up, they actually have been heavily tested and shown to reliably provide just as good contact (almost identical measured resistance) as wire nuts do, and being much easier to use correctly (and be sure you're _actually_ getting correct contact inside, since you can actually see it), they really do seem to be the better choice nowadays, not just for convenience but also from an objective electrical standpoint. It's understandable that people would be wary of a replacement for something that's served them for so long, but every once in a while new things actually can turn out to be genuinely better... I agree that insulation-displacement contacts (such as the device in this video) for this sort of thing do seem a bit dubious, really, but people shouldn't confuse Wagos with insulation-displacement contacts. They are _not_ the same thing at all, and Wagos actually are quite legitimate in how they go about things.

Those things look terrifying they are a fire just waiting to happen. If you ever are planning to hide a junction box (for whatever reason), buy a junction box from the UK they are much better and safer than what is available in the US. wires are held in with screws, rated for 250v at various amperages they are usually in fire resistant plastic (bakalite) boxes and if they have the 'kite mark' I believe they have been tested to 600v at up to 600 amp. Ideally you should never hide a junction but then ideally you should never drive faster than the speed limit. If you want to install pot lights then their downlighter boxes are you best friend closely followed by the ceiling rose junction boxes.

All the lights and plugs are put together using this method. In the mobile modular's. I had to fix wires that obviously needed it and I use the same method are difficult to pull part for reason.

The lesson learned: plan and place your junction boxes more carefully. They are required.

[@brarautorepairs]

No NEC will not allow a splice to replace a junction box unless it is a repair. This would be in case your wire gets damaged. Still, sometimes adding a junction box isn't the end of the world. It just needs to be covered and painted to match the room. I've seen smoke alarms used as a junction box before to hide a previous repair.

[@jentronics3754]

They are normally found in trailer houses, a manufacturered product, not a locally contracted electrical job requiring a inspection. If I used them in a job, my inspector would fail them. It isn't illegal to sell an item not legal to use. For example, in plumbing a S traps are illegal to install but you can still legally buy them. You need to ask your local inspector.

I would never hide one of those inside a wall. I'm surprised it's approved. Hopefully not in Canada.

Soldering is legal, or used to be and properly twisted and soldered wires capped with a Marette is a permanent, zero ohms repair. That goofy splicer looks like a fire waiting to happen IMO. BTW, similar knife type splicers are often used for 12V wiring and they can and do burn up especially once a bit of corrosion has set in.

[@FamilyFriendlyDIY]

Lots of opinions in the comments as to whether this is safe or not. These are used to splice sections of manufactured housing together (double-wides). But the NEC allows them to be used for repair as well, not for new work. They are getting hard to find, but I think they're still out there somewhere. It might be the C-word that has made them scarce, and not that they're being discontinued. It's been that way for a lot of electrical supplies, especially where I live. The BEST way to do it is definitely a true junction box. If it's in a decent spot, the junction box could be an outlet or light box. I've heard of lots of guys using metal boxes (handy box with a handy box cover plate---though PLEASE NOTE this is not legal) twist the wires really good with wire nuts, and put the good metal NM clamping connectors on each side of the box, then bury the box in the wall. In my opinion, that would probably be better than these connectors-- though I can't recommend it. ---If there were a short in the metal box, your breaker should trip before any damage could be done. Just my opinion. Thanks for the comment! - I guess KZbin edited the above comment with a strikethrough

[@willhwiltjr]

you could always run a new set of Romex sure its a pain in the ass but all the equipment you would need is a decent fish tape just start where the junction would be and snag one of the wires and run pull it out of one side replace that wire with your new Romex and then run the other wire backward (fish tape attaches at the receptacle/switch/box and pull on the wire to advance the tape to the junction where you then hook onto the new Romex before fishing it the rest of the way.) granted you may need a second person to feed if you're covering any amount of distance or crossing planes i.e. ceiling to wall or wall to perpendicular wall.

[@MichaelBeale]

Something I came across online that's relevant here: I noticed an odd phenomenon of private individuals selling bundles of Romex wire in various non-retail online marketplaces...never by bulk lengths, but usually in the largest pre-packaged (sealed, plastic wrapped) spool offered by the manufacturer. The people selling it didn't otherwise seem to have obvious ties to construction supplies, so it was odd to me. WELL... It turns out, these large rolls of residential Romex wire have become a target of theft nationwide. The word got around among the dregs of society that these bigger bundles (not offered in store by Walmart) are at a wonderful little "sweet spot" of: 1) High value, especially for something that size and lack of loss-prevention measures. The bundles are relatively accessible and compact, and they available in most any supply store. 2)There's always lots of willing buyers in need of Romex, especially buyers looking for any and all ways to minimize their expenditures. And so this has resulted in a black market. There are now people (quite likely involved in drug trafficking) who have begun accepting payment in sealed bundles of Romex...almost like its a unit of currency!?! Makes you wonder what the 200'RomexUSD currency exchange rate is, huh!? 3) The bundles are still LOW enough in value as to grab a few/a cart full, yet still remain under these new arbitrary limits for prosecution (usually ~$1000) recently set by newly installed leftist DA's in many American population centers. With Romex being a reasonably known product, its had this affect where - hypothetically - store employees can't easily argue that the value of the goods was obviously well over $1000, and so they have much less plausible justification for intervening and preventing the theft by physical force. So the Romex just walks right out the door...the thieves drive/run away...cops are called...and then nothing happens. If arrest are *SOMEHOW* get made after the fact, the charges are usually just dropped now, for no good reason. So now here we are, where a large portion of these rolls of Romex in this country are not sitting on store shelves - but instead filling up shady storage units in "urban" areas. This obviously can't continue, if we want to have a country. But yep - that's the reason for the specific price paradox you picked up on. There's just literally been so much of it stolen that its directly resulted in price hikes to help cover the losses.
