Thank you to everyone for the great info. I will be sure to use those resources and then double check with national grid by sending them a diagram of everything I am going to do. I really wished the building was permanent so I could do overhead. Looks like that conduit in your pictures never saw any glue. Usually the conduit glued properly should break when being pulled out. Something that came apart that clean looks line no glue used. I never knew about slip fittings just read about them in the document I got from national grid.
