What's wrong here?

You mean the one that the Cowboy installed for the fire pump in this circuit?

Joe are you sure that that is not a FMC fitting. The flex looks like it is swelled out a little just like it would if the proper fitting was used and there is a fitting that looks just like that one.

It is hard to tell things like that from a picture.

It is not a greenfield FMC "Flexible Metal Conduit" fitting, and if it was that would be wrong as well, a fitting for use with "Sealtight Liquidtight Flexible Metal Conduit" looks like this one, for an example.

I checked again, and it was a FMC fitting, it looks like an EMT fitting, but it is one that looks like this one and is still incorrect:

Joe I hate to add a debate in this room but is myself i never see that kind of combo of fitting and IMO with EMT compression fitting it will not fly around here espcally if you mention viberation area but is that type of conduct is a questionable one if that is nonmetalic verison or it have inteal metalic verison.

Merci, Marc

The only thing I see wrong is the fitting for the liquidtight flexible metal conduit.

That screw coupling looks wacky to me .
Just walked in ans it was the first thing I noticed.
I am under the impression that the Liquid tight male end should screw directly into a female coupling.
This is not what I see .

Improper use of fittings.

The rigid metal conduit coupling is only for coupling sections of rigid metal conduit. It is not for transitioning between two raceway types in this manner.

EMT/LT Combination Couplings are available for this use and are also identified for this type of installation in the NECA standards.

Here's an example of one:
