Today on the job I had to hang conduit on a ceiling for ceiling fans stubbing the end of the conduit into a sheet-rock wall. I was to push MC from the switch up the wall to the conduit and through the conduit to the fan box. I didn't think it would make a difference if I pushed the MC all the way to the fan box with out removing the metal protective spiral. These are residential ceiling fans installed in condo's we are upgrading. We were using 12/2 MC cable. Is there a real reason why I shouldn't have been doing this. I was told it wasn't the right way to do it.
 
Why would you want to push 12-2 MC thru conduit ? If you have a complete conduit run from switch to C-Fan individual conductors would be the way to go. THHN. What size conduit was used ? 1/2 EMT I think would be difficult for 12-2 MC. 3/4 EMT would be minimum if you chose to go that route. But WHY ?
Welcome to the Forum.
 
It sounds like the conduit only runs from the fan exposed on the ceiling then into a wall and needs to connect to the switch thats in the wall.. They want to run mc from the switch to the fan. Im only guessing
 
Maybe I didn't explain what was going on sufficiently. The 1/2 inch conduit ran from the fan box along the ceiling to the sheet-rock wall directly above the switch. The conduit stubbed into the wall only 2 inches and at the height of the ceiling, I was supposed to use a change over and run MC down the wall to the switch. For me it was easier to push the MC through the conduit than to push the 12/2 minus the metal clad. It was just easier for me to do it that way. The conduit was only 10 feet long but there were saddles and offsets. We are remodeling a building with 50 condo's.
 
From 1/2 in emt connector to coupling to mc connector is a long changeover for a wall . maybe a flex to emt would work. Any mc or flex connector woth a 90 needs to always be accessible.

What fitting did you use at the fan box? Sleaving is OK and they make change over fittings if you don't want to use a ridigid coupling but you can't have MC sticking out of an EMT connector.
