Moving switch and receptable boxes

Sure it's possible. I'd like to see one in the flesh

The current run of This Old House involves a (very high end) prefab and they showed those connectors. I have the same question I had years ago. If it is safe and legal to use one of those connectors by itself, can I put one inside a metal junction box and hide the whole thing?

They remind me of the "vampire clips" sometimes used in automobiles and trailers to tap into the wiring harness.

Never liked 'em 'cuz they typically work after installation but always seem to fail in some manner later on - loose connection, rust, etc. I'm surprised to see a NEC approved version.

I wonder how long it will be before failures start and they remove them from the code.

Or who paid how much to get them approved to start with.

That looks less safe than just using wire nuts in a concealed junction box. I don't even like using those "vampire" connectors in vehicle wiring. For household wiring, I would rather connect the wires by twisting, then soldering, then screwing on a wire nut in a junction box. How could they fall apart? How does an electrical inspector find a concealed junction box anyway? Just asking, I haven't done it.

And, for example, if one of them happened to get wet or subject to a high humidity situation?

Perhaps like aluminum wiring when first approved for residential use and then showed problems and even fires!

Any links to where can one see a picture/diagram of the NEC approved (inside-a- wall) approved connector????
