I've got an architect that wants me to run my feeders and branch circuits under concrete. Tha main panel will be in a mechanical room and the person running the project said that he didn't think that I could penetrate the walls/ceiling because of the firewall. I have 4 main panels in 4 rooms with probably 120+ branch circuits that would all be under the concrete. It is obviously easier to go overhead with everything. It looks like the International Building Code allows conduit penetrations of walls with a fire rated sealant. I haven't seen anything addressing ceiling penetrations.
I was either going to drop into the panel with feeders from the ceiling and send the branch circuits out through the ceiling. This work is for an assisted living wing and everything will be in conduit or MC cable. I was planning on penetrating the ceiling with EMT on the feeder and from there going to plastic since I was out of the fire wall area. All opinions and options are welcomed.
