Looks TN-S but the PME sticker makes me think otherwise!

Thanks for this Paul. I haven't come across a TT system on-site yet, so great to see what it looks like in reality!!


Sorry meant to quote from the TT rod photo from post 59. Still it saves a bit of space.

Good points E54, I also wouldn't pig tail the earth cable. Wonder how long the connection will last exposed to the elements like that?

Just a note: Never pig tail a live conductor, you've basically just made an induction coil.

Coil it around the rod...can someone do the maths on that one please?!

This has got me a bit confused, i was initially thinking TNS with the earth coming from the base of the cable but im swaying to TNCS with it running through the fuse..

Very similar to the first picture on this thread.
It is possible that the earth does not join the neutral in the head but more likely a "conversion" to TNCS from TNS

Hi all, since I'm only in my first year of my Level 2 C&G 2365 electrical installations it's always nice to be able to look at different set ups and recognise what they are, I saw the following and wanted to know if this one is a TN-C-S or TN-S install because I was thinking a TN-C-S but it looks like it's connected to the sheath so that makes it a TN-S install???

Thanks all

TN=S. it's clamped to the lead sheath of the supply cable.

Thanks for confirming that for me
