I was looking at a detail on a drawing for connecting branch circuit power cabling to a metallic raceway mounted above a backsplash, the detail indicates MC cabling in the ceiling space, where the connection is made to the raceway there is indicated a piece of EMT in the wall cavity to the accessible ceiling space where it indicates a transition to MC to the panelboard, my question is is there such a fitting to terminate MC into at the emt stub at the ceiling space (at a building column) strip back 5-6? and pull it thru the fitting and the EMT to the raceway? It would have to terminate the mc on one end with a set screw or some kind of compression fitting on the other end. I cannot seem to find a fitting like this as opposed to putting in a j.box at each location? Thanks.
