Conductors Considered Outside the building
Conductors Considered Outside the building
(OP)
It is my understanding that in order for conductors or cables to be considered outside a high rise building NEC 230.6 shall be applied for the installation of the vertical raceways encased in concrete not less than 2 inches thick. Can anyone tell me what type of conduits are allowed to be installed in the vertical raceways and how are they to be supported ? Please reference the NEC CODES that appropriately provide an answers to the latter questions... Thank you in advance

"so any type of conduit that is otherwise allowed by the NEC would be permitted" Please explain THE FOLLOWING " otherwise allowed by the NEC" allowed where?
RE: Conductors Considered Outside the building
For example, the NEC wouldn't allow ENT for a medium-voltage feeder so you can't use it for your application encased in concrete.
