I'm not convinced that the correct fitting was used. I don't see much of that 'all plastic' stuff, so I don't know if there even IS a single connector for that use.

Since a section of the stuff is used, the EMT wilol need to have a ground wire in it.

The application, while it can be done this way 'legally,' is a bit unusual. I'd take that as a clue that some untrained folks were playing with the electric, and look at everything a lot closer.
