Ceiling Fan Installation for Pergola
When the weather begins to warm up a bit I would like to build a deck with an integrated pergola. This will be part of a larger project and the plans have been produced by an architect. We would like to install a ceiling fan into the pergola, but that it turning out to be more complicated than I had anticipated.
There are many UL wet location listed fans available, and of course we'll wire the deck with either UF rated cable or THNN/THWN running through conduit, but what I cannot figure out is what sort of electrical box to use and as such, how to attach the fan the to pergola rafter.
Am I missing something? Are there wet location listed fan boxes? Can I build out a box around the rafter to protect the junction box/connections and then use a pancake box? I know it has been done, I just don't know how people pull it off.
Any help?
