Splice kit approved for behind walls?

[njbraskey]

Hello all,

Last week a friend put a screw through a wall and straight into a wire. They called out an electrician who cut a small square of the dry wall away and added the splice pictured below. I was surprised when he told me the electrician said he could go ahead and fix the dry wall to fill the hole now. My understanding of the code (which is limited) from 314.72 D is that all splices would have to be installed so that the conductors are accessible. Is this some type of new splice that's allowed to be hidden behind walls or was he misinformed?



Thank you
NB

To my eyes, the wire itself looks to be more of an issue, as it appears to be a cord.

Cords can't be used as a substitute for the permanent wiring of a Premises Wiring (System).

welcome to the forum. yes, they make in wall splice kits for NM that meet 334.40(B) - no jbox needed:

eta: that one you have is made by TE Connectivity

However what Al pointed out may be a problem.

a single 240 bc, or is that a mwbc. 3 blacks and a red ?? or is that red-blk-blk-gray? doesnt even look like proper cord.

It looks like a Red, Black, Blue (dark), and a Brown.
Definitely not standard US colors for NM cable.

looks like cord. those colors do not seem to match US even using mixed alternate colors.??

maybe its red-blk-dark grn-gray ??

Even though the connection may not need a junction box I would still say there needed to be some form of access to it! Maybe just a wall access cover. Someday those plugs will need replaced.
Those plugs look like something used quit often when joining two halves of modular homes together in which I typically see them shoved up above the moisture-barrier-plastic in the underbelly of modular homes. Not easy to find at times but somewhat accessible.

My understanding of the code (which is limited) from 314.72 D is that all splices would have to be installed so that the conductors are accessible.

That article applies to circuits over 1000 volts, and is therefore not applicable to this installation. I don't have time to look for the "under 1000 volts" version of this requirement. But I will observe that this article does not talk about wiring and splices being accessible. It says that the wires inside a box need to be accessible. If there is a rule about splices that are not done inside a box being accessible, this is not that rule.

It's an article 400 cord with white, black, red and green.

may be, but the green and white is an odd shade of those colors in the pic.

may be,

Not 'may be' it is.

but the green and white is an odd shade of those colors in the pic.

Whatever .......

 

[K8MHZ]

Are those even designed to be used with fine strand conductors?

 

[FionaZuppa]

Whatever .......

the wire on right is not white.

Almost certainly is.

the wire on right is not white.

I think it is-

Could be the lighting in the pic isn't optimum and maybe the clear plastic is a little clouded over. Maybe we're wrong- maybe the wire is ns tc, maybe it's some weird speaker wire, whatever it is, it isn't legal- that's the most important aspect.

That "white" definitely looks gray to me, but isn't gray also permitted for the neutral?

Work with a lot of rubber cord and you find white is often not bright white like THHN etc.

Its natural grey.

Meant to say that the application of the cord wasn't legal, not that the cord itself was illegal.:slaphead:

Yes, code wise it could be and the one in the picture "might" be.

However while I have not handled every rubber cord produced I have never found one with a natural gray neutral. I do find rubber cords with very faint pigments. Reds that look pink, blues that look green etc

At the end of the day whatever color that is the product is not NM, it is cord and not code compliant with that type of connector.
