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.
