Fcu problems

[Elmariachi]

Does anyone know why my fcu has supply and load as normal and an extra live for load and supply?? Ive had to re install my original fcu because I just can't get it wired properly.

I have added a picture.

It is two modules in a single plate Fuse and switch are separate and meed to be linked as in the image.

Yeah that looks just like what I had originally but no power.

Just went back to the original set up and its working well.

Must he an issue with the fcu. That or issues with the amps.

The fuse is fine.
