Can indoor Romex be used in conduit for outdoor use?
My friend is adding motion sensor lights outside at our house. He plans to install conduit in the garage, and use indoor 14/2 Romex, Type NM-B Indoor. He then will add the same outside to the security light fixture he is installing.
Can indoor Romex in conduit be used for this? We live in the desert in Southern California, where temperatures can get over 120 degrees in the summer.
