Right ... Just been nudged to set this up by Paul.M and sounds a good idea following recent threads I've done in the Arms..

Rules....No Offensive material... edit if required before posting as this is the public arena.
Anything to do with the trade or in and around it ...H&S pic's welcome.



I've posted this a few times and this is at a mates house following a kitchen refirb several yrs ago. mg_smile:

This is what the cutout would look like if it were PME/TN-C-S

As you can see from the label it says not to connect the earth unless all the requirements are met. This property is in the middle of nowhere and I’m guessing they couldn’t get the Ze low enough to have PME.

Have you read the notice on the service head.

 

[timhoward]

It isn’t. I confirmed with the DNO. There’s no earth connected to the cutout.

In order left to right on the earth terminal are: rod, main cu, PV CU, EV CU.

Do you know what the PSCC was? That sticker normally means PME is fine, but warns you not to just reconnect any old main earth to it without checking it meet the requirement to support the bonds (e.g. 10mm +)

I'm going to make a wild guess here, I think it was an early EV install and whoever did it decided to TT the whole place to make life easier.

Yes, now have a read of the other pic I posted.

I can categorically 100% confirm it is not PME/TN-C-S

 

[brianmoooore]

There can be reasons not to use a DNO TNC-S earth terminal, even when one is aailable.

 

[Raptor0014]

As I said I confirmed with National Grid that it wasn’t PME.

Are you saying that it's not available, in spite of the sticker?

No idea if it’s available or not. They stated the property is not PME and is on TT according to their records. There is no earth in that cutout and one has never been connected

I’d guess the sticker is on all the cutouts regardless and doesn’t determine anything as it states if all the conditions aren’t met then don’t connect the earth to that terminal.

Maybe they’re supposed to pull them off but they probably expect an electrician and anyone authorised to work on the cutout to know what they’re looking at.

 

[westward10]

I cannot fully read the notice but unless we understand different English it states PME is available.

 

[brianmoooore]

It's probably available, and the sticker should be there in case circumstances change and the requirements for TNC-S can be met.
I've had to TT supplies brought into a few ramshackle corrugated iron clad farm buildings, where sheets are in contact with the ground and bonding requirements are impossible to meet.

So do we think that whoever fitted the EV point removed the PME and did the crappy TT?

 

[timhoward]

I've always taken that notice to mean "PME is possible, but make sure our side of things comply".
Not saying I'm definitely right but they do have another sticker design saying "No earth provided, the earthing type is TT" or words to that effect.
(I've apparently only got a bad photo of one which you can't read!)

So do we think that whoever fitted the EV point removed the PME and did the crappy TT?

I did suspect that, but he says there's never been an earth connection, i.e. the knockout isn't knocked out.
So I'll have to look for somewhere else to be cynical tonight.

No they apply the stickers individually when fitting cutouts and will fit the appropriate one, have you done a Ze to the terminal under the blanking grommet ?

No I didn’t as it hasn’t ever had one connected. So didn’t touch anything on the cutout.

I’ll be back there in August as they want a circuit running for aircon. So will have a look then. But odd that the DNO didn’t mention it was available. They just said their records show it’s TT.

Only other thing I can think is they never connected one as there’s quite a decent solar and battery setup (in terms of generation and storage) so maybe they did it to go full island mode and not rely on the distributor earth. But that’s just a pluck out of thin air guess.

Anyway, well done on the earth rods!
It's not your fault if you got someone following company policy to deny all existence of ever having provided an earth to anything, anywhere. They once told me that a lead cable that had a damaged braid hanging off it had never been TNS. Thanks to this forum I had the reply ready. "Ok, no problem, but I'm sure you'll agree that it's extraneous and needs bonding....". Long silence. Then "We'll send someone out".
