I'm adding a circuit in a metal building. The wall that I am working on is solid block(impossible to fish down the inside of it). I'm going to surface mount box and EMT pipe. ????Can I run MC cable to the pipe and skin it long enuf to get to recept box and run it down pipe. Of course I will use a MC connector with a rigid sleeve and then to EMT connector. THE REASON I WANT TO DO IT THAT WAY IS BECAUSE I CANT PUT A BOX IN THE CEILING BECAUSE THERE IS NO ACCESS-----I'M ONLY LUCKY ENUF TO FISH A WIRE THERE.When I get the wire thru the ceiling I will put it all together and then shove the sleeve and connectors in the ceiling so they cant be seen.Owner wants to see nothing but pipe.
Biil: See Section 300-15(f) Fitting. A fitting identified for the use shall be permitted in lieu of a box or conduit body where accessible after installation and not containing spliced or terminated conductors.
and the NECH Commentary:
300-15(f) Where a cable system makes a transition to a raceway to provide mechanical protection against damage. Section 300-15(f) permits the use of a fitting instead of a box. For example, where nonmetallic-sheathed cable that is run overhead on floor joists and drops down on a concrete wall to supply a receptacle needs to be protected from physical damage, a short length of raceway is installed to the outlet device box. The cable sheath is removed for the length of the raceway. The cable is then inserted in the raceway and secured by a combination fitting that is fastened to the raceway.
PS: Use of the correct fitting will allow visual inspection of the "redhead"
Thanks for the reference. I assume there would be no objections to the method I described? That would basically mean that the MC would be connected directly to the box via proper connector and EMT is just used as a sleeve and strapped to the wall?
Mae West: hmmm ... conduit supports? I don't know what to call them or why they're known as "Mae Wests" (except maybe the profile?)
