Hey everyone. Any reason we can't run Shielded 18/2 FPLP in slab for a parking structure if it doesn't leave the building? Or in other words do you have to pull direct burial or wet location specific wire for in slab(smurf) conduit? I have always pulled the regular indoor 18/2 knowing that if it left the building like out to a pull box or man hole of some kind then you need outdoor rated cable. Any kind of documentation, code reference or anything like that would be most appreciated(for or against)! Have a great day!
