Not yet. I wanted to make sure I was right before I call the guy out on it. There may be more to it after I call him out on it. I’ll update and buy the beer when I win this bet. :laughing:
You'll win the bet hands down. Ken and Pete are good at having the NEC codes in digital form so they can post them. Me, not so much.

Hacks do this all the time but it's not correct anywhere in the US.

2011 NEC definition of concealed in article 100. The real question is answered somewhere in Article 314 somewhere.

Edit 314.29

Don't bet yet... There's a code compliant no-box splice out there. However, the catch is that it has to be able to be fished out (i.e., accessible).

Isn't there an approved connection to do this per code?

It seems to me there is an approved connection you buy to splice a wire.

Cool product if it is legal. I'm in full conduit land. I'll wait for 480 and Speedy for a potential verdict. They can do Romex where they work and probably know the scoop on this product.

Understood, but the question was, "is a slice ever allowed".

I'm not declaring it up to code everywhere. I just know they exist.

My electrician said he would be more comfortable leaving a wire nutterd and taped splice before leaving this connection in the wall, ergo why I possess it.

As far as I can tell, they're legal under QAAV of the UL White Book.

NONMETALLIC-SHEATHED CABLE
INTERCONNECTORS (QAAV)
GENERAL
This category covers self-contained interconnectors employing pressure
cable connectors, insulation displacement or insulation piercing connectors

These devices have been investigated for equivalency to Type NM cable in
insulation and temperature rise, and for capability to withstand fault currents, vibration and mechanical shock that may occur during transport of
the units in which they are used.

Whenever you think you're making a crazy positive bet, pause, then pause, then back it down to what you can afford.

If it is in Denver you would loose. They adopted the 20124 NEC with no changes, Littleton/Highlands Ranch only has one amendment and it is administrative.

Most of my work is in the land of conduit so no splices outside an accessible point.

There was an episode of This Old House where they toured Ted Benson's timber frame shop where they build all the walls modularly and they used these non-metalic sheathed connectors to prewire the whole house. Not sure if it's applicable in your area, but I had never seen/heard of them before.

It's at 18:44 of the following video

I know they use them by the bucketful for manufactured housing. When they marry up two sections, there's connectors there to hook up the wiring.

And I've done plenty of service calls on said manufactured houses to know that it gets very expensive to refeed a circuit when the set-up crew doesn't get one put together right.

I pass on using them regardless of AHJ acceptability. The only time I would use them is in the lower level of a house build on flood-prone land where the house is literally on stilts and the lower level is sacrificial to flood water, tidal surges etc.

So, no-go on conventional stick-framed, or otherwise "site-built structures".
