I am getting ready to wire a boathouse that sits on 40' pylons driven into the bottom of the lake. The boat house will have a finished ceiling for lighting and a few electric boat lifts. He wants switches mounted on his 4X4 post close the the ceiling for the lights over his boats. I was planning on doing most of my wiring with romex and slleve the switches out of the ceiling. I have been looking through the code book to find how this structure needs to be wired and the only thing I have found is " Marianas and boatyards. Is there another section to look at. It is basically a finished building with little work exposed. I am setting a 100-amp panel in a wall that is hidden and built for a bar. Thanks for any input on this subject
