How can I identify my supply type?

[plugwash]

yeah sadly that bit of the workmanship isn't yours or the householders to inspect/fail

and bs7671 has no legal power you can't force the rec to comply with it.

anyway i can't see why it would be a code 1 its bloody obvious which one the neutral is especaillly with the labeling in place so i can't see how it merits more than a code 4.

I dont like the tails from the CU stripped back to ident the colour - use adhesive tape, but better still, half inch of heat shrink.

Why is the Red coloured meter lead in the Neutral side too? - it looks like shoddy workmanship to me - If I did an inspection - it would be a Cat 1 Fail.

That is a bit churlish, whilst using one colour is hardly good practice, it is hardly dangerous and certainly not electrically unsound. I would agree that the installer is at fault, but the installer was likely the local REC, and your comments and provarications have no power on them.

Yes both the live and neutral have the outer stripped back by what looks like over an inch.

He could fix those though because they are downstream of the isolator.

Oh except that some funny guy put in a 2 pole isolator and then only used one pole, so the neutral isn't isolatable.

But that shouldn't be a problem because it's PME (although without the notice) so the neutral is at earth potential... unless there is a neutral fault

Is that four faults?

1. Neutral not put through isolator
2. Wrong colour tail used for neutral between meter and henley
3. Tails to CU outer sheath stripped back excessively
4. No PME notice

I'm curious - why do you need to know which is which?

What are you going to be doing to the tails where it would matter to you which was which before you'd taken the cover off the CU/Henley block/Isolation switch/whatever?

I've seen an installation with separate Henley blocks for the live and neutral, at the Burghfield Aqua Sports Club club house.

In that installation the tails are of the type where the outer sheath is coloured (red/black) throughout its entire length.

One wonders whether there would ever be any unnecessary confusion if the tails were grey outer sheath with no inner sheath visible at the terminals.

Nothing wrong with that. And unless you proposed to work on it live, of no consequence which was which.

If the installation is Pme I hope that Your equapotential bonding is in place!!

REC wouldn't give PME to a swimming pool open to the public And try hard not to for private pools aswell. I fit is unavoidable, a steel mat needs embeding in the floor, and bonding appliead to diagonal corners.

And as for petrol stations....

The Burghfield Aqua Sports Club is basically about waterskiing and wakeboarding which take place on an (outdoor) lake

 

[Lectrician]

Not a pool then....communal changing rooms in leisure centers also do not use PME in my experiaance!

Petrol stations defenantly dont, this is due to circulating network currents in the pipework of the pumps underground.

 

[user56565]

this is definitely a PME supply.

 

[plugwash]

this is definitely a PME supply.

and your grounds for saying that are?

it could quite easilly be a TN-S fed with split concentric. I agree it's most likely PME but you can't tell for sure without seeing the connections inside the cutout.

 

[Lectrician]

The type of cutout that is there looks like a PME only type (one brass N/E terminal only with no link on it).

TN-S ones are usually a little wider in my experience, and the earth leaves via the side, or via a very exposed terminal on the top right.

I didn't want to commit to an arrangement either - you really do not know 100% until the cover is off.
