All help appreciated with this one.
I am currently training for C&G 2365 level 2.
Here is a photo of the MET in my flat.
As you can see, it is TN-S.
But how do I know what CSA the cable from the sheath is ???
Because it's double-stranded I'm having a hard time judging.
Looks like something between 4 and 6 mm2 to me but I could easily be wrong.
It is an old installation, probably 1960's to 1980's is my guess.
Oh, and it's a looped supply which also goes to the flat above me.
