where should this wire go?

[wildwest]

Howdy all, got a question for yeh.
got this big green and yellah wire hanging out of my consoomer unit, shouldn't it be connected to somit? them other two big grey ones are.

 

[wildwest]

The sticker on it says its been inspected, so it'll be alright till 2028. I seen some other big green and yellas wires come out the top with all them little grey wires. theyr clamped on to the oil and water pipes.

Another Metal Clad board and no protection against the metal of the board for the tails entering it

Thats why plastic is better isn't it?

I feel connected with The Earth by just standing on it. No need for the green and yellow earth wires at all.

You'll be under it if you don't call an electrician in to sort it out.

Ok I'll come clean sheriff, no one is at risk here,
I know where that wire goes.
Its a TT system, Ra=33ohm . The tail is there for the DNO to attach to the PEN PME or what ever you want to call it. When someone gets round to asking them to come and do it.
I'm just at the site to restore power to the poo pump that the electrician (who left his name and number on the label ) disconnected when he installed the shiney new box and found a bit of earth leakage.
The pump was supplied from a JB on a radial socket circuit hidden under the bedroom floor.
He wasn't to know, he thought rats had been under there so he dissconnected at the next to last socket where he cleared the fault and went home happy the little old lady was now protected by 2 lovely RCDs.
Trouble took a while to rear up its ugly smelly head.
The real question is where is the earthing electrode.
When I was at the site I couldn't see it so I texted the electrician.
The spark said it was buried under the extension.
All I could see was EQ bonding to the oil pipe with no plastic jacket dissapearing into the ground and the EQ to the water circulating pipes.
Do you think the hidden electrode and the EQ bonding will take the fault current should someone start yanking on the line tail so that it chaffs and contacts the box. I=V/R 240/33=7.2727A
I think them wires will carry that current for quite a long time.

Cheers for other half of story ,
(slightly concerned R2 cable)
(-looks like it has more in common with R1 )
(- going by old colours )

Same places as the grey one with the brown inner.

Do not connect with the other green and yellows, very dangerous.

The OP is a new member and probably joined just to get an answer to this question. He might take such frivolous and what we know to be, sarcastic answers as genuine advise to be relied upon. We know how many people will then 'give it a go' themselves. Sorry Rob, but I think this was an irresponsible reply that could have caused injury if he follows it up.

Ignore bits in brackets ........in my earlier post..
mistaken top seal - for scruffy R2 remains !
(- my eyes are dripping -)

OP admits it was a frivolous question.
I texted spark for a copy of the cert for the board change, he called back,nervous. Told me earthing was bad at the property.
I think 33ohms is quite good for a TT system, only wish I could have seen the top of the electrode and a nice label like the one at the eq bond on the oil pipe.
But not being paid to check up on someone else's work,
only make the poo pump work.
Spark said he was in a scheme and BC notified.
Spark thought system safe enough to walk away from.
OP not so sure, no cert from spark , still the poo pump is now working

He was clearly posting as a joke.

 

[wildwest]

Only, its not really a joke is it Rob?
<<<<some electrical work going on, really is shocking

This tail has more of a tale if you will.
Its starts back in December with a little old man and little old woman who live in a house by the sea , they have been there more than 30 years happy and sad.
They decide to buy themselves a new cooker.
They have one of those companies come that will deliver new cooker and take away old cooker. Operatives who do the disconnection of the old, and connection of the new have only basic training.
They do not like the look of old system and refuse to connect new cooker. Saying it is not safe.
Leave aged couple frightened and confused with only limited means of cooking, toaster and kettle.
Electrician summoned. New box fitted without EICR.
Problems ensue. RCD trips.
Old people can't reach it.
Electrician returns, finds earth fault, disconnects.
Time passes, sewage overflows.
Nasty expensive difficult and confusing for Aged couple.
I hope the lesson here for young sparks who may see this thread,
is that if you are called out to an old system that some nob says is dangerous, inspect it test it and document it as well as you can, before you consider anything else.

And if you must change that horrid wooden backed bakalite thing for a nice new ammendment 3 CU, use a plastic Tail Gland.
