UK Acceptable ways to terminate SWA - standard practice question

[littlespark]

<div class="bbWrapper">The “real world problem” is as I described. <br /> 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. <br /> <br /> <br /> The galv box, then flexi conduit is a valid solution… or move the sw/fuse to accommodate taking the gland directly.</div>

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.</div>

Oh and mark with coloured cable ties. Two full days to get to this point. What a faff.</div>

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.</div>

<div class="bbWrapper">Im just pointing out some safe practices..... <br /> but to me, the henley block cover is off, and the service isolator to the right of the meter is turned on....<br /> <br /> Maybe the photos were taken at different times....</div>

The tails for the henley to split the supply are there in front of the isolator, perhaps my description wasn&#039;t the best worded. But the supply to the switched fuse is not yet connected, that will be connected when I&#039;m ready for supply and testing in the workshop.</div>

 

[littlespark]

<div class="bbWrapper">So what is connected to the henley just now? 2 sets of tails...?<br /> <br /> Im sorry for pushing it... but like you say, hard to tell with just pictures..... maybe a wider angle showing everything.</div>

So the supply will go to, and split, at the henley, one set to the existing CU, one set to the fused switch, when finished. <br /> Right now, the supply is untouched and the henley is dead, as it is not connected to supply yet.</div>
