DNO I worked for would never allow 3rd party equipment on their board. However when taken over by another DNO it was allowed. New DNO would allow those 60amp MEM switch fuses which were compact to be fitted usually top right hand corner.

That's fine if the cabinet/enclosure is of sufficient size to accommodate the extra devices. I'm just trying to think of a typical Cabinet/enclosure where it would all fit in, not using the back fixing boards that usually take up the whole rear of these enclosures... must be a bloody big cabinet to contain a 3 phase cut out and all those meters and switch fuses etc!! Got a photo??

Been trying to upload a photo but cannot for the life of me work it out!!!!!!!!!!!

That would kinda defeat the whole point of having a switch fuse if the tails are over 3 metres. If that was the case i'd be having a few words with the DNO's Area Engineer, rather than listening to the meter installer.

I concur. My switch fuses nearly always go next to the cut-out

Are you not meant to have 1 point of isolation? If con-unit indoors, then 2 way unit fitted in OMB that creates 2 x isolation points. I know done like that years ago with several con unit/ sw/fuses installed by the meter position.

Good point DMan is it not the same as splitting the tails inside to add a shower unit or the like?

A switch fuse to protect extended tails is more for their benefit than the customers installation. I've not heard of a DNO not allowing a switch fuse to be mounted in an external cut-out cabinet!!

The sunny boys have cramped all their equipment inbox, meter an all. lol
