The Rome’s is still NG outside, in Carflex or whatever.

BTW, what is that 2x4 wood framing? Interior door (closet or room). Looks like the 2x don’t make it all the way up, or are they adding more? Is that 1x a header? Also interesting is the method of attachment of the top and uprights. Looks like they notch overlap, as opposed to the uprights being inside the top plate.

The wood is just for the door frame so they have a place to screw in the hardware and nail in the casing.
They are inside the C channel on top. Maybe the picture is not clear on that.
I agree on the NM, no matter how they hide it. The strange thing is the tray cable would be legit. "In a raceway" is one of the accepted uses in 336.10. I am just not sure how they would have to continue on once they got inside. I suppose they might terminate the NM in the disconnect on the wall. That makes is sort of legal. It is about like feeding the jelly jar next to the door or a surface mounted FS receptacle box outside.
My bet, they strip the jacket and pull it through the Carflex, pretending it is THWN.

Tray Cable marked with TC-ER is not listed for interior use without a raceway or cable tray system...see 336.12(2)

But...according to 336.10(9), tray cable IDENTIFIED for use in 1 & 2 family dwellings is allowed...this cable is said to be marked with TC-ER-JP

JP for joist pull.

It is an interesting product. I never really saw it before. The stuff I saw was not marked JP. That could make a serious dent in the NM and UF market.

Hi guys...the TC-ER cable is a Tray Cable and can not be used inside a building unless in cable tray or a raceway. That TC-ER cable was supposed to pick up a listing for use in 1&2 family dwellings in accordance with 2017 336.10(9) with a new marking "JP" for joist pull. So you would see TC-ER-JP...but I have not seen any of it on the streets.

There is a product in the supply houses around here that some are starting to use...

Here is a link...

I was surprised to see the TC cable. It was the first time I had ever seen any on a roll and I helped myself to a few inches of it, just for a look. They were using it for the LV on a minisplit.
I really see no reason why it would not take over the NM and UF market tho.
