I always thought a concealed splice in the wall was a no-no. The picture looks like low voltage. What is line voltage acceptable? Butt splices or crimps with heat shrink, wirenuts? (probably not), some type of set screw? Or am I on the wrong page here. For example could you eliminate a wall switch or outlet you don't want with a proper splice and stuff it in the wall?334.40 B 2014 says yes for a repair.
Yes, I was quite sure of that. Again that looks like a low voltage connector, is there a listed line voltage connector for that purpose?A standard wire nut, crimp, or screw connector is not allowed to be concealed. The connector shown is specifically listed for that use.
Can this connectors be use legally? ... in WA?

Define low voltage - to some it is anything below 10kVYes, I was quite sure of that. Again that looks like a low voltage connector, is there a listed line voltage connector for that purpose?
They are often concealed in the modular homes as well when connecting from one section to another.I think the connector shown in the picture is of the type that is typically used to connect the halves of a modular home together. Designed for NM.
Not too sure if I would use one for a concealed repair myself.
It as a change for 2014 -- submitted by the IAEI no less. However NIMH (Not in my house).
Possible that NEC finally recognized them in 2014. They have been around for a while, and primarily used in mobile/manufactured homes that are moved in sections to connect each section together, and often were being buried in walls, would assume they were listed for that or the homes in question shouldn't have passed their certifications.So not allowed in wall until 2014 code cycle.
Understood, but at same time the product is (presumably) listed for the purpose. Wouldn't 110.3(B) allow something that is not otherwise mentioned elsewhere in NEC to be used according to it's listing?It is still a connection behind the wall and in order to get to the connection the surface of the finish of the building has to be disturbed. I don't see how it passes inspections??
