What's that cable going off at 4 o'clock.....looks a bit iffy.

edit....Don't say alarm clock, tel.
 
Can you distinguish the earthing system from this.
Would the cable dropping down to the outside armour of the incoming be an earth.

It's hard to distinguish the earthing system from the pictures, having a lead incomer suggests TNS, but it could eaisky have been converted to TNCS.
What equipment is installed where the service enters the installation?

The Cable that appears to attach to the incoming cable is most likely an earth, but its not possible to say for sure from a picture.
 
It is a metalclad wallbox used to feed mural wiring services. It is PME as can be seen by the 16mm earth wire from lead sheath to neutral conductor although it should have a PME label fixed.

That is somewhat bigger than 16mm nor can you make assumptions.
 
But it does look PME'd though.

That's a very big 16mm!

You cannot say for certain from that picture that it has been converted to TNCS, it is likely, but not guaranteed.
 
paint it in 3 different fluorescent colours and put a £7million price tag on it.
 
After over 40 years in power distribution with a DNO ,I know what a wall box is and what 16mm is.
Unless it has multiple layers of insulation I would guess at 35mm minimum, compare it to the mortar between the brickwork.

Well go on then if you really know please tell all.
