Its use should be confined to dry interior locations because it has very thin plating that does not protect it from rusting when exposed to the elements or humid conditions. It is less expensive than rigid conduit and much easier to install because the process of bending requires less effort and the ends do not have to be threaded. In comparison to the other wiring systems, it ranks behind rigid conduit but ahead of the other types of wiring when considering the quality and durability of the installation. For this reason and because of the ...
