Need Some Advice / Guidance

I can not see any earthing conductors at the mains intake.There is nothing wrong with using the trunking and conduit as the C.P.C. but I can't see how this is earthed back to the consumer unit.

this is where the stupid sparks came in

they removed a metal board which the conduit was connect to it, and shoved a plastic crappy one in but not redoing / terminating the earth so atm its not earthed as i would of thought they would have done it when they changed the consumer

Understand. But AB is saying there should still be a main earth terminal....the original metal board should have been connected to it.

yea there is on the side of the main i guess you would call it fuse holder (main incoming supply)

tncs supply if it matters

Just couldn't see it in the photo and I thought it was the case regarding a metal conduit from the old metal C.U. to the trunking being removed and replaced with flexible PVC conduit removing the earth continuity.

Yep another thing for me to sort / fix

 

[Toneyz]

No this is down to the electricians who installed the C.U.

Well you would think will give me a bit of ammo anyway

I'd call that a BAZOOKA.......not installing a main earth

 

[Toneyz]

Have you got any photo's where the original C. U. is shown with metal conduit between?

 

[Corbs]

No sorry but it was the same connection as the sockets

Coupling and brass bush

Only know this due to the coupling still being on the end of the conduit

Has anyone noticed the rather random arrangement by which the MIG welder gets its feed? There are 3 single phase meters. One feeds the SP+N C/U, the other two feed the spot welder switchfuse directly (which has no N or 3rd phase, so I suspect the spot welder is single-phase 4ooV, run between two lines. Then those two lines loop out as the blue cables in flex conduit up to the 3-phase MIG welder switchfuse which gets its other phase from the SP+N CU. If any of these three are after the main switch in either the CU or the S.W. SF, then part of the installation will remain live when its main switch is turned off. Hopefully they are before, in which case they are extensions of the meter tails, so probably still a bit naughty.

And yes, there seems to be a lack of green-and-yellow!

Yes, naughty indeed. I think I might be contacting Mr Pryde, the NIC approved contractor.
Not much pride in his work, by the looks.
Is the neutral looped between meters 1 and 3?

I'm back again

Any chance I could be given temporary access to the arms @Marvo as I've got the testing info ?

I'm afraid the Arms is only available to professional sparkies who've been regular contributors to the forum. You can post the test documents here for discussion, I don't see why there might be any right to privacy issues with such documents.
