Q. A commercial, new construction job being done with EMT and MC cable. The electrician has constructed an extension of a 12-2 MC circuit into a ½" EMT system by doing the following:
Stripping the sheath of the MC cable leaving a long length of the inside wires; putting a 2-screw-type MC connector on; next a ½ rigid coupling is threaded onto the MC connector and an EMT
connector screwed into the coupling; then a length of EMT is slipped over the length of wires and runs to the next outlet box.
Is this an approved installation? Does it matter if it's exposed or inside a wall? Does it matter the length of the EMT extension, such as 6", 3', 20'?
A. No, this is not an approved installation.
