Hi to all, I'm a newbie and enjoy following this forum. Most of my work is commercial but currently am doing a small residential 200 Amp service with a through the roof mast kit. My question is about the connection between the 2 1/2 inch mast and the meter socket hub. As supplied by my electrical supplier, the pipe is not threaded and slips over the hub and is held in place by a set screw. Is this screw the only thing, besides the mast clamps, that holds the mast to the hub ?? Thanks to all who reply. This is a Canadian project.
