So I remember in Mike Holt's video when he discusses having a flexible cord coming out of a disconnect with a cord connector that that was a violation of 400.7B I am reading 400.7B and it states "Where used as permitted in 400.7A3,A6, and A8 each flexible cord shall be equipped with an attachment plug and shall be energized from a receptacle outlet or cord connector body." So if the flexible cord comes out of the disconnect and has a cord connector on it then the attachment plug is being energized from a cord connector body. It doesn't make sense to me that I can have a receptacle outlet J-box that can have a flexible cord and connector body hanging from it but I can't with a disconnect. What am I missing here?
