The footpath and streetWhat is on the other side of the wall.
I wanted to avoid having to make it good afterwards.Is there a reason why some space could't be made above or below the light? This question has been asked more than once, but I don't see any meaningful response.
10 min per light with an SDS and cables could be made off properly, then a bit of Tuff sheath or HO7 brought through the rear in a single stuffing gland.
It would be as easy to do this right as mess about with less than ideal 'solutions'.
How come?Doesn't matter what you do 12 months down the line half of them probably won't even be functional.
Fact of life, put a light fitting into an external wall or floor and nature will see to it failing.How come?

Also, the cable is buried in the construction of the wall. If we SDS’d above or below, it will need some digging before the cables can be released.
Which is why I said the outer sheath goes into the stuffing gland, it clamps down onto the pvc outer, its just that the SWA bit isn't glanded to anything. You are aslo saying the SWA must be earthed, maybe you can tell me why it must, other than the regs saying it should. What possible scenario may happen if its not earthed, we are talking about a cable sandwiched in a brick wall here, not under a flower bed etc. Like I've said, I've done exactly the same thing with copex and flex which complies with every reg so why earth the SWA?SWA isn't just flex with steel armour and an outer sheath, as has been suggested. The stuff that covers the basic insulated cores is not to be considered a sheath, and in many cables it's just what is referred to as bedding. This bedding is often fragile and crumbles as you try to remove it. As such, it would not be ideal to try and use a stuffing gland around it to provide water ingress protection.
And the armour must be earthed, as already strenuously noted.

Forget Regulations, consult a cable manufacturer and ask their opinion then post it on here.Which is why I said the outer sheath goes into the stuffing gland, it clamps down onto the pvc outer, its just that the SWA bit isn't glanded to anything.

That could be said for loads of things though, ceiling grids, metal stud work, pipes that cross cables, double insulated fittings, socket screws in dry lining boxes, just a few of the top of my head. Chances of it happening though....zip. And even if it did the rcd would save you.If there is damage to the cable resulting in contact between a core and the steel armour then nothing will happen. The steel armour will be live and nothing will trip.
I think you must know this though.

To suggest an RCD would save you is naive and shows a lack of understanding of ADS.That could be said for loads of things though, ceiling grids, metal stud work, pipes that cross cables, double insulated fittings, socket screws in dry lining boxes, just a few of the top of my head.

Well you when you touch it, and if you don't touch it, so what if its live, which it wont be, only in a bookworms fantasy worldWhat would an RCD detect if a live conductor was in contact with armour that isn't earthed?
