Thoughts on this consumer unit change

[MickSmith5824]

Hi all

Been asked to quote on this consumer unit change (see photo). Wondering what people's thoughts are on the earthing situation. As can see it is tns but earthing doesn't look to clever to me. It's stranded ali by looks of it. Not sure of CSA of it, looks like could potentially be 10mm at a push. The tails are 16mm and not sure on main fuse size. Could this potentially be compliant? It's likely I may need to relocate new consumer unit as limited for space so in an ideal world would take the main earth into wall mounted block and then from here to consumer unit and to water and gas. As can see from photo the gas is bonded straight from service cable also at the moment.

Any clarification on this would be appreciated.

U need pull fuse too

Put earths into isco disco, 2 way board

That is probably a pair of bare tinned copper 7/.044 conductors.

Isco Disco? Lol. No discos yet their banned. As long as Ze readings good, you wouldn't have any concerns with earthing set up?

So you think probably no need to have any concerns then Westward? Aslong as Ze is good?

How are they connected to the supply cable the picture is a bit dark.

Where does the MICC on the left go to?

Looks like the Bare tinned copper go a copper band / screw and nut on the supply Westwood10

 

[westward10]

If they are 7/.044 then the pair of them are a smoke paper short of 13.0mm.

You'll need to sort out that g/y earth connection from the incoming cable. That earth clip on lead is a no no. Where does it go, bonding or what?

See close up photo Westward may be a bit better

It's bonded to gas service mate. Plan was to just take that into my MET

Well spotted. Is it feeding something else, off another phase?
...and how is it earthed?
Straight from fuse(s).... not isolated?

Still not clear enough.
