I was at the supply house the other day, and one of the counter guys showed me a splicing device that he said could be used in lieu of a box and could be hidden inside a wall. The device is made by Tyco and is called: Nonmetallic (Type NM-1) Sheathed Cable Splicing Device 1116377.
When I looked it up at the company's Website, it mentioned NEC 545, 550, 551, and 336-21 under "Agency Approvals," but those articles deal with manufactured buildings, mobile homes, RVs, etc., which I don't work on. I perused 300.15 and the related articles listed in the FPN in 300.15(E), but I'm still not clear as to whether this device could be buried inside a wall. I've always operated with the idea that splices must be in a box and remain accessible, so my gut tells me I can't use this splicing device if it's going to be covered up at some point.
Anyone have any experience with one of these?
