Opinion on Supply System Type Wanted: TN-S or TN-C-S

[Ian1981]

Yes TN-S
As you say your test results of pssc and pefc are what they are.

If it was PME. Both stranded cores would go into the neutral terminal, with the main earth being tapped off from there

I would go for TN-C-S.
If you look carefully at incoming supply, the concentric cable has only 2 conductors. The centre line conductor and outer stranded neutral. Part of the stranded neutral has been seperated and used to feed the earth terminal. (Effectively creating a link between them) the remaining strands have then been painted black to form the neutral conductor.

So to my eyesight, which is not what it was, it's combined in the service head, therefore TN-C-S.

Time to go to spec savers I think, there are clearly three separate conductors there!

I think devonchris might of been on the drink, if he thinks someone would get there paintbrush out, and start painting the copper strands black
