I have a building whose main electrical room is 2 floors above the utility transformer. The service lateral conductors are routed through building encased in 2" of concrete (230.6). The way it was routed worked fine until a foundation change during construction forced it to be rerouted. To avoid a grade beam under the bottom floor slab, more that 360 degrees of turns in the conduit are required.
Question: if we use a pull box in order to afford a few more turns, would those conductors still be considered outside of the building?
Thanks.
