I'm currently the foreman on a multifamily project. I've been asked by my boss to complte the house breezeway lighting by running 12/3 From the house panel thru the ground fl. unit to each floor above thru the ceilings inside the dwellings. My Question is whether there is a reference in the code on how to establish a raceway btwn floors . I have been told to use 1" EMT conduit as a sleeve. In addition use bushings make the conduits extend 2' below and above the penetration. 2HR FIRE RATINGS ON THE CONCRETE
