I’ll guide you through safely preparing and splicing a piece of Romex cable. I'll quickly show how to cut and prep the wires, then use a splice kit, to ensure solid contact and a professional finish.

I would be interested to see if there is a degradation of current flow through these connectors. A test similar to the one you did comparing wire nuts to wago connectors would be good to see. I can't help but feel that the "fork" splice will limit current flow and heat up under a max rated load.
I'm not an electrician, nor an accomplished electrical DI-WIRE, but I don't think I would trust that in my home, or especially not a rental. Your other videos outlining why the commercial receptacles (outlets) are superior to the residential grade ones flies in the face of the technique used by that splice connector. Daisy chained outlets today are being loaded up more than ever, and with the continued electrification of everything in homes, that trend is likely to continue. So, if you've got 10-14 amperes being drawn through that connector with only that tiny little sliver of surface area contact made to the actual conductors, that thing is definitely going to heat up, and that will likely cause movement. It seems likely that that would lead to an intermittent connection at best, and arcing at worst.
The concept is neat but it looks a bit flimsy. Thank you for sharing
Isn't that inferior to screw terminals and wire nuts for conductivity at higher amperages?
Something to keep in mind, using these types of devices greatly reduces the surface contact of the conductor. This can lead to voltage drops, current drops and possible overheating at the connector. You want to maximize contact surface area.
Whether or not it's "approved" ( I haven't asked an electrician) but I've always learned toward using an insulated butt connector. That way you have maximum contact of the conductor. Again, I'd check with an electrician before putting it behind anything, like drywall or i the ceiling. I've only done this on external wires like extension cords, lamp cords, etc.
It isn't approved. Most approve butt-splicing devices outside a box look somewhat similar to this. Generally speaking these connectors, although approved, would be frowned upon by most electricians.
These are UL listed and compliant with 2014 NEC 334.40 (A) (B)! I know that it would appear that the pair of metal contacting forks are undersized but remember it’s the total cross section that’s important. In this case it’s rated for a steady state operating current of 20 A which means it would need to be tested to a 20% higher current level to protect against unintended current spikes! Like with any electrical work, if you’re not comfortable and competent hire a professional.
Mobile home's double wide have thies and you will change out the breaker before you figger out its thies plastic connectors all melted and burnt.
Those cutters are for much smaller wires in electronics..,
Is that a non flammable splice?
Maybe 10 years ago at a continuing education class they talked about these one time only NM cable splice devices. S couple of residential sparkies said they never had any problems with them.
Thanks for your video, is there an amazon or home depot link for this product?
As a quick fix, temporary, sure! Permanent in my own home? Not a chance. And if I hire someone to do this, I will never pay.
I love your channel and have watched for years. When you say "approved", who is approving this? Like you said at the end, I too love all things Wago. Keep up the good work, brother!
Approved by the city code inspector
I'm pretty saw I viewed this a year or more ago.
What about just soldering the wires and covering the wire with heat shrink tubing?
Knob and Tube
My Dad soldered many connections wiring houses. Junctions in boxes and open air connections.
"Friction Tape" for the insulator.
Before wire nuts and when lead was good!
What could go wrong? Everything.
Yeah, unfortunately many of the switches and outlets in manufactured homes use similar connections. Not good.
It was pulled from Amazon, and it is not known if it will be back. That tells it all. The brand is TE.
Bare romex behind drywall. I would never do.
Tyco Romex splice kit was the only one I know of that is rated to be buried in a wall.
they all are: NSI, Molex , etc 334.40
Service guy's nightmare
What could go wrong, metal squeezers on cheapy plastic onto not perpendicular wire cutter/grabbers. WOW NOPE
The problem is it was approved by the International Consortium of Chinese Landlords so you can only obtain them in cartons of Lesser Panda cigarettes. And you aren't allowed to use conduit to support other conductors via zip ties or any other water-brained hillbilly implement.
Behind drywall? Can you say house fire???? So many issues have been linked to that style connection. As the wire lives it's life it expands and contracts and those are dissimilar metals meaning they expand and contract at different temperatures and different speeds which causes a fault in the connection by creating increased resistance which means heat which leads to fire. Then the wago is neat but still junk. Do it right the first time spend the extra and it pays off in the end. Temp circuits sure on both but long term no.
give us a link! "SO Many issues" I put together two 30 unit modular apartment buildings each with 36 ranch size sections and everything was interconnected with Molex splice kits and they're still there after a decade and I know for fact they have zero connection issues
Does this product have CSA approval. I wouldn't trust this product.
Gotta love all these wanna be sparkies that act like boomers when it comes to change. O No! This is junk because it's new! I know more than UL labs ans5thisnis junk.
The clamp into the box is not even correct
Definitely loose!
Assuming the electrical fire doesn't kill you or your family the insurance company typically will want an investigation done before paying out any money, telling them that you saw a guy on TH-cam do it is probably not going to cut it with the insurance people...IMHO
I would never use these in a house I sleep in !!!
What a horrible, dangerous idea. The area of contact is insufficient for its intended use. Not UL approved and no longer available on Amazon.
they are UL approved and 334.40 compliant. Have always been UL approved.
@@ajmarqueling I can get at any of my electrical supply houses. NSI brand. Yeah, HAHAHAHA Amazon! hahahaha they sell quality stuff! HAHAHAHAHA. AMAzon: the benchmark of quality.
What bull s is this
it's not.
