16mm T&E to Consumer Unit

[davesparks]

It's TNS, that's a split concentric cable coming in with the earth strands being brought out of the bottom of the cutout into a separate single pole Henley block (a genuine Henley series 7 one)
That Henley block MET will have been supplied by the DNO.

I've had a couple done exactly like this by SSE on service alterations where they have maintained the TNS service.

You sure that's TNS ?????

Yes, that's a split concentric cable (much bigger than CNE cable) with the earth strands brought out of the bottom of the cutout.

On,y difference to way I've seen it done before is that they've added some g/y tape, I usually see it with bare copper strands.

Afternoon everyone, I've just been to a neighbours house who has just her home completely done up as the foundations are shot. The house has been rewired and in doing so the consumer unit has been moved to one side of the house (the main fuse is outside on the other side of house). I've gone to swap a light fitting over for her and have noticed the elec contractor who's rewired it has used 16mm t&e supply. The cable is buried within the wall so not sure what protection they've used, i might dig out some of the plaster to see. The main fuse is an 80A (the seal has been cut off the fuse carrier so i checked). There are 1 x 10mm for shower, 1 x 10mm for cooker, 1 x 10mm for hob, 3 x ring circuits, 1 x radial and 3 x lighting circuits. The job must have been signed off already and I haven't done any cable calcs yet but it just doesn't sit right with me. Has anyone came across this before? Opinions? Thanks in advance.

OmyDays its normally the supply authority who have a terrible installation, a sub main with no mechanical protection burred in wall with no RCD on a 100a fuse.

I have never seen such a bad consumer install on a new service head, i know what you mean i would just price accordingly mate.

This is how my old boss kept on telling the electricians to do it either 16mm T &E down cavity with polystyrene insulation or behind dot and dab although a KMF switch fuse was fitted it often had a 100A fuse fitted. The problem got worse when consumer unit had to be put at part M height yes you've guessed it down wall , I kept on telling him it did not comply the NICEIC kept on telling him in the end we both gave up. Removal from the approval roll .

Why it's so strange to not use SWA
