I'm designing the supply to a purged enclosure located in a paint room. I am wondering if TC approved for C1D2 can be used in a C1D1 environment as long as it's properly installed in Ex conduit and sealed on the ends? NEC 501-11 (1) says of type 'extra-hard usage' should be used for flexible cords, but it doesn't call out an approval. I have been able to find a C1D2 cable but not C1D1.
Thanks for the help.
