earthing system?

[mgzr]

having a slight disagreement with a maintenance guy on a job im testing...

just a bit of banter, but can any confirm this earthing system..?!

Looks like TN-C-S.

Home made pme ?

We would need to know whether any wires "escaped" for that one.

Perform a Ze impedance test... Max Ze for TNC-S is 0.35 Ohms... Apologies if the Ze value is wrong, I was 16th Edition before I buggered off

These are the max loop values used by WPD

if PEFC = PSCC, it's TNC-S.

it's a funny arrangement. 4 black fuse carriers and 1 white one. is that PC idea of racial equality?

What do you think.

Agree

There goes the type testing.

Something that looks TN-C-S may not be all it seems. This head I came across has all the attributes of TN-C-S but apparently is not.

I think the sticker kind of gives it away.

 

[GBDamo]

What was his argument for it being TNS?

Did this go to a Ryfield board or cut out prior to this then it would be a "red dot"holder/solid link and the TNC-S would be separated there. This happends in a lot of blocks of flats where the meters are near each flat.

 

[westward10]

Much as you say Ant and was a block of flats.

TNCS IMO, however test it
