Is This A Pme?

[Stoneman]

Looked at a job yesterday. The suppliers kit looked recently upgraded.

There is a facility on the suppliers incomer to connect an earth - but, there is no labling to say it is permissible to use as a PME.

I've tried to upload a pic but it's too large.. I've cropped it and it workedaq

Btw, what is the easiest way to upload raw pics from your phone?

You would have to ask the DNO if it is TNCS or not,

And if it is TNCS, they will tell you it's PME whether it is or not.

They claim all their TNCS are PME, which is a blatant lie,  IMHO.

Can't tell from here, as the Stepps says , you'll have to ask them .

I don't see an earth terminal on there.

 

[Stoneman]

The black cover allows access to the N terminal and the moulded case of the incomer does have an earth symbol on it together with cable entry points... There's no official PME stickers though.

As suggested you will need clarification from DNO. Whilst the head may appear to accommodate easy access for pme doesn't mean that's what it's being used for.

Where's the earth?

 

[Stoneman]

Zero earth - 1000 ohms Zs.

I should've pulled the fuse really. The old dears have DNO fitting PME & cut out next week.

CU is wooden wylex.

It's been bothering me!  What would you do...?

 

[Rob_the_rich]

Is there main equipotential bonding in place? If not, I would consider fitting it asap. I know you are not supposed to use gas pipes (or water) as the earth, but it is better than nothing in my opinion.

Edit; also fit an MET with an earth wire to the consumer unit so it is ready for the DNO, might as well terminate the main bonding at the MET too.

Hi all. I might be wrong here, but it was my understanding that if the DNO turn up and there is no evidence of suitable earthing and bonding arrangements having being made, they they will simply refuse to "re-energise" the installation. I would be sorting that out first...

john...

Why not at least bang a rod in for now. Then if they say it is PME and you can use their earth, you can swap it over.

Better than leaving it with no earth?

 

[Sharpend]

I have to say why ?

Please tell me you haven't left the install energised without an earth? Please tell me that you put a temp rod in at least?

 

[NozSpark]

Why bother putting it in as temporary...?

 

[Sharpend]

Coz I thought he said that pme was being installed? Can leave if you like!
