Are electrical conduits permitted to penetrate slab edge perimeter fire containment systems? We are trying to feed outlets located on the exterior wall but structural vertical C-channels in the exterior wall system prevent the conduits from reaching them. We are considering feeding the outlets from floor below but this would require penetrating the perimeter fire containment system.
Hello Amador - thank you for using the AskHilti platform. This is a great question.
We do not have a listed system allowing for conduits to penetrate through the edge of slab, however this is a condition we can address with an Engineering Judgment.
