#4/3 SER cable is to be run from inside panel in the "interior" of the home ceiling, til it comes out under their deck ceiling that is to be enclosed. The ceiling will be enclosed probably with aluminum or vinyl, but not the walls. My opinion, since it will be enclosed, is that I can still run the SER in the ceiling area until I come down to the "Spa panel" then protect it with pvc conduit. The ceiling will be enclosed, thereby making it a "dry" location. What's your thoughts? Thanks
