why is this even permitted? just nuts IMO .
I know that UL is not the NFPA that handles the National Electric Code, but how can that fire hazard of a product be permitted by any licensing body? Instead of the NFPA mandating Arc Fault Circuit Interrupters, they should be banning that type wire connection, which is barely suitable for low voltage.

Why is it permitted? because its listed by an NRTL

when you think about it, push-wire terminals aka backstab terminals have about the same amount of contact as this does and its only being held on by a spring instead of instead of a sharp edge

It is listed by a NRTL, Nationally Recognized Testing Laboratory, such as UL, CSA, or others, they are used by the manufactured home industry, & RV manufacturers, if my memory serves me correctly AMP was the 1st to introduce it, supposedly a time saver by not needing a box, plus no splices, I would hate to come behind & have to service them.

I'm guessing the design if primarily to facilitate use in thin walls.

Dude did not show much of the inside of the back-plate that holds everything in place. I assume a special tool is used to "crimp" the entire assemble together.

I see nothing wrong with it.

...You don't use a punch down tool to install receptacles?
The guy who installed the one in the video that failed obviously did not. An improperly pigtailed commercial grade receptacle can present an equivalent danger. I admit to some years of trailer life in my past, and I think the IPC wall switches might have been the only thing that DIDN'T fail. They must have had a proper punchdown tool.

The electrical item I most wanted to choke the mobile home manufacturer for was the contactor that brought on the heating system. It sounded like a NEMA 4 motor starter bolted to a piece of sheet metal followed by the rush of a 3600 rpm blower pushing air through a too-small uninsulated duct. Given the trailer insulation, on a cold night this happened about every five minutes as you tried to sleep. The wall switches never kept me awake and to the disappointment of my ex-wife, I didn't die in a trailer fire.

I've never been a fan of insulation displacement contacts. And those look worse than T-taps or Skotchloks.

Trailers, just like tract homes, and multi family dwellings, are built as cheap as they can get away with, and the definite purpose contactors used in HVAC equipment is the same, they are designed to last a certain number of operations and as long as that is longer then the warranty period, it's all good.

I built a really thin wall in my basement to make a closet wide enough for a standard door. I found a really shallow plastic electrical box at Menards and was able to mount a standard outlet. One of the tricks was to only run one cable to box so I didn't have to pigtail it.

When I first clicked on the article yesterday, thought it might be about those "audiophile receptacles"

Discussion forum about them. :( https://forum.audiogon.com/discussions/audiophile-grade-wall-receptacle

Now THAT's insane! :LOL:

This post from that thread says it all:

But the whole electrical system behind your wall and to the street and to the power company is made of non-audiophile grade equipment. Putting a special outlet at the wall just before your components doesn’t improve anything. It’ll just pass through the noisy electricity that is already there. Fortunately, the engineers that designed your equipment account for this in your devices’ power supplies… where that AC gets converted to DC to power your electronics.

Sorta reminds me of all that Monster Cable audiophile nonsense.

No, those are "audiophoole receptacles". These are the same phooles who pay $800 for a souped up 10 awg power cable that does all kinds of marvy things to the sound. I read of a guy who put one on a DAC that drew about 15 watts and it "transformed his system" almost as much as the cable lifters he bought to keep his cables off the floor. There is a clown in Japan who had an audiophoole power pole installed that fed the dedicated service to his sound system.

They speak **** like this with a straight face...

Also avoid a Hubbell Spec grade or better outlet that has a nickle plated brass supporting backstrap and nickle plated brass contacts The nickle plating has ferrous materials in it and causes grain in the sound presentation. Not as bad as a steel backstrap though.

Yeah, that "nickle plating" really screws things up.

I sold a lot of monster at tweeter in the early 00's...it sure did wonders for my wallet!

When you are not rich and do something outside the norm you might be called crazy or worse.

If you have enough money you can be elevated to Eccentric.

then you havent analyzed the differences between the 2. a sharp edge biting both sides of a conductor is a lot different than a flat piece of metal touching one side of a conductor with a spring in the strap for tension
I doubt that I can remember or even search for the formulas to determine the current carrying capacity of a couple of thin knife edges, but I wouldn't push 15 amps through it, proper punch down tool used or not.

You do realize that it has been tested by an NRTL in a lab? So it has been proven that it can carry 15a.

I know that you must have seen UL listed devices that are total POS's. IMHO this receptacle falls into that category. We can discuss skin effect and other attributes of how current is carried, but I do not trust that type of connection for this application.

Cost reduction has it's place, but not here.

Thankfully I aged out of that hobby due to hearing loss, but I can say that mild hearing loss is good for your marriage 😂
I "overspend" a good bit on sound equipment, but I could buy a nice new touring motorcycle for the difference in price between two sound systems whose performance differences could be confirmed by oscilloscope traces but not by blind A-B comparison listening. Unless you are in the Gates/Musk/Bezos class purchasing decisions have an opportunity cost. My entire budget for audiophile tweaks remains unspent.

Helped a friend design an build an "audiophile" level speaker system in the early 80s. Speaker cabinets were huge, and I can't remember what components we used besides Klipsch horns. I designed and built the crossover network. He built the cabinets and bought the speakers.

We had a listening party where all the audiophile buddies came by and they raved about the speakers. Funny thing was that the mid range speakers were accidentally disconnected. I too could not tell the difference, and as a result, my interest gradually tailed off.

WTF?????
As a Communications Contractor, I am very familiar with this type of connection. I use it all the time in cat6 plugs and jacks. Carrying milliamp range current on 23ga. at a few volts up to 30 or so, no problem. Carrying REAL electricity?? Not In My House!

I've never seen them used in houses, just RV's, mobile homes, but they are UL approved and manufactured by respected companies like Pass and Seymour (Legrand).

Absolutely nothing is "approved" by UL, they list a product if it meets the standard set for that product.
