Another Interesting DNO Supply In MICC

Is there actually a pot seal under all that tape?
I guess there is a BS951 onto the sheath?

For those of us that do not know what your on about...
What are you on about?
Perhaps it's just another picture of a service fuse incomer, designed to attract interest - as most photos of incomers seem to do on these pages!

1. Yes!
2. Sort of. A bit of copper band-the sort they used to use in the 60's.
I'm not sure of the rating of that cable. It seems to be fused here then runs through the wall to next door. Either that, or there's a solid link in the cut-out.
Still, I think an odd choice of cable to run through one house to another: it's got no mechanical protection.
It doesn't need it. It's pyro.
Remember this one from a while back?
It's a 4 core doubled up to provide a SP&N supply.
That pyro ran through to the next property.
It ran across a wall at 45 degrees for around 5 meters, buried in plaster with no indication of it's presence.

This one also disappears into plaster. Imagine drilling a hole to put up a shelf, though?
Who would the DNO hold responsible for the damage?
At least if it were surface-mounted & protected against mechanical damage, the DNO would have done as much as they could to minimise damage, bearing in mind the (not so obvious) route through another property.
Can either of these mineral cables carry 100A?

You could maybe just about squeeze it through a 10.0mm², but you really ought to be using 16.0mm² for a 100A supply.
Not sure what size mine was. Maybe a 4H4? so probably undersized, and yours doesn't look much bigger.
I would think you could probably force responsibility onto the DNO should damage occour, and they would no doubt just surface cleat a bit of straight con in it's place.
IIRC, surface mounted pyro only requires mechanical protection if it is below 4' from the floor. If it is flush it is ok.
This may not be a reg, and just a rule of thumb, but thats what I was taught by an old fellar master of pyro
