thoughts please

i went to look at a new development yesterday that was in the middle of second fix stage,bit of a strange set up and wanted your thoughts and what regs have been contravened

external meter cupboard
3core 16mm swa terminated into plastic switched fuse then ran to consumer unit inside
terminated directly into plastic CU
inside core used as the main earth terminated into earth bar in the consumer unit
16mm earth taken from earth bar which then Is terminated onto the swa armouring by a bonding clamp to provide an earth.

just seems like an absolute mess and a long winded exercise rather than just using a metal clad switch fuse

That's an interesting picture, 100A main switch owned by electricity supplier not to be touched by average spark, a struggle to fit a switch fuse in which should be metal and they are bigger... and not to mention shoddy termination on the swa...

Actually that isolator is intended specifically for the average spark to connect to. There is a seperate lid covering the dead side of the isolator which is unsealed, the live side is sealed.
It's an alternative method to the self connect meter with its integral isolator.

looks like a temp supply to a site wired by builder monkeys.

Nope that SWA feeds a first floor flat.
