I recently came across this DNO cutout and wanted to get other opinions on its current state. 

I'm trying to get a better understanding of what is "good practice" when it comes to commercial and industrial installations.

For me I notice...

- the main cutout is positioned upside down. 

- the extra cable entering the top connecting a single phase, with the exposed earthing conductor connecting to the MET. 

Is this acceptable and also is there anything else that that would require attention?
