Hi all, new to the forum and looking for a little input. I've got a 400 amp overhead service on the side of a building. 1- 2 1/2" grc into a CT cab with parallel 3/0 copper in the same raceway. From CT into 400 amp mlo with 2- 100amp breakers and 2- 200 amp breakers. Inspector here says can't have more than 1 "set" of conductors in a mast, underground would be OK but not overhead. Help please. Thanks in advance.
