There are many types of electrical conduit to choose from for projects including galvanized rigid steel, PVC, PVC-coated steel, aluminum and fiberglass RTRC conduit. The best type of electrical conduit to use depends on the project. When integrated with IEC standards, planning becomes more reliable and. Although the type of cable and conductor is the determining factor in the fire behaviour of ducts and conduits, the choice of cable tray type and the installation of the latter in line with installation precautions are just as crucial. Cables are very rarely the source of a fire. This would only. Conduits can go through fire-rated walls and floors, meaning they should be treated as penetrants and therefore fire resistant with a tested and approved firestop systems. Helping to avoid the passage of fire and smoke from one compartment to another.
