I can't find this anywhere. If it is a repeat, I apologise. I have a cottage on the beach. It is on stilts and the underside is completely exposed to the elements. I am currently upgrading the electrical from the 1954 wiring to something a bit safer. How do I properly route wiring underneath the cottage? Does it need conduits? Is normal Romex good enough? Is the metal sheathed wire what I need? Please help the idiot!
