UK Acceptable ways to terminate SWA - standard practice question

[littlespark]

The “real world problem” is as I described.
The white inner sheath is not classed as being enough mechanical protection for just floating around in free air. It’s more just a bedding to keep the actual cores together.


The galv box, then flexi conduit is a valid solution… or move the sw/fuse to accommodate taking the gland directly.

Probably get the odd red 'X' for this, what what I would do, and did on one occasion, where there was little practical option, is to fit a galvanised adaptable box onto the SWA gland, fit a large stuffing gland to the box as well, slide off the outer sheath from some 25mm tails, and slide these over the L and N to the CU, trapping them in the gland.

I would do something similar, however, all you need is a 25mm bush instead of the adaptable box, then use some flexible conduit to protect the cores.

The supply end will be earthed. I just havent done it yet as I paused to ask for some advice.

I can see why the white sheath ideally should be covered but in truth, in this instance, cannot see how that may be achieved nor what real world proplem it would cause as it is.

It's NOT a sheath. It's simply bedding. It cannot be exposed.

Yes I well understand that, sheath, bedding, scemantics on word useage.

In any case. I got the SDS and chisel out. adjusted the blockwork to make room for the SWA to bend. Im not 100% happy with it, it has pulled the fuse switch box out of square, but the cover still fits. Just need to pull it out and drill for the earth cable.

All done, just need to rake the tails out of the isolator and put them into the henley, and put the extra tails I ran into the isolator when I am ready to connect to supply. Oh and mark with coloured cable ties. Two full days to get to this point. What a faff.

Sleeved the black in green/yellow, yes?

And you put the lid back on the Henley block before turning on the isolator? (After dead testing)

No I thought pink and orange might be nicer, and who needs lids?

Black is marked with green and yellow tape as have no green yellow sleeve the right size. Grey is marked with blue sleeve. And yes, of course the henley will have a lid before the circuit goes live, its left off for now as I need to be back in there.

Im just pointing out some safe practices.....
but to me, the henley block cover is off, and the service isolator to the right of the meter is turned on....

Maybe the photos were taken at different times....
