Romex Splice Kit 2 Wire, 1/Clam

A:  Great question. You might want to reach out to the manufacturer for your local building inspections department. I personally wouldn’t reuse one that I found in the wall but if I wasn’t happy with something while I was actually using it I would have no problem taking the wires out and reusing it on the same job. You would definitely wanna strip fresh wire and I wouldn’t decrease the gauge. Go from (12 to 14ga). 

A:  Hi - It is marked as complying the U.S. National Electrical Code 334.40(B) for years 2005 and 2008.  Each jurisdiction decides when (and if) they will start using the new electrical codes.  Some may still be on 2008.  Many are on 2020.    Back then (2008), this was legal for both repair work and renovations, new construction, etc.   In 2014 and again in 2020, that section was changed to say only for "Repair".   Honestly, it is way better to make a splice in a small metal box using properly tightened wire nuts.  The few times I have had to extend a wire in my home, I added a length of wire, and then put a blank cover on the old box and painted it to match the wall.  It is barely noticeable and 100% legal and 100% safe.  Not buried and findable if there is a problem.  And if you properly ground the metal box, then it will protect against arcing and should pop the breaker.     I did buy one of these, but discovered the VERY fine print inside the package that says it is not rated for wire made before 1990, and of course, my house was made before 1990, so I can't use it...

A:  only if it's is for repair please refer to 334.40. not for REMODELS!

A:  Yes it meets code for remodel/existing conditions.   It does not meet code for new construction. 

A:  These are UL listed for the purpose. As an electrician, I have used these in every romex situation and never had a single problem with inspectors about it. 

A:  I dont remember the cost but I got them through home depot online.

A:  I reached out Directly to Tyco and was told they will not be manufacturing any of these nor any of the 3 wire splice kits, or 2 wire splice and tap kits.
