Don’t know what GN8 says.Hi - so are you saying that GN8 is wrong or that I’ve read it wrong? .
I just go by the sizes for the British Standards and the values for K in BS7671.

If the CSA of the Steel Wire is 26mm2.Am I missing something here?
If you know that the cpc is 26mm, why do you need to do the adiabatic?
Apologies if I'm being stupid.
That’s where I got the 41 mm2 from....If the CSA of the Steel Wire is 26mm2.
It’s not a given that the copper equivalence will be sufficient.
Here’s a link to a chart produced by John Peckham, for at a glance checking the CSA of the Steel Wire is sufficient:
Use SWA as CPC, a guide to the acceptability of steel wire armour use as CPC. - https://gadsolutions.biz/regulations/swa-as-the-cpc
Sure this has been posted in the past.

My chart is slightly different from John’s.That’s where I got the 41 mm2 from....
Depending on which body you talk to the armour on swa is acceptable to cable that has cores of 95 mm and under but it's never a bad idea to bring A10 g/y with itafter my rather vague thread Friday about finding the 30 mtrs of 10mm 2 core swa In the back of me van.....after some views on earthing to the shed, 3 options as far as I’m aware are
1. Run a single 10mm from main met upto the shed and use that
2. Use the armour of the swa, adiabatic permitting..
3. Connect the swa to the main met at source end and TT the shed
Each option is appruthe same cost wise and it’s my own house so Labour is not a big issue, as per title just after others views and preferences....
Do the maths don't forget about the insulation double thickness over and under the cable,will work out you need to use 6 mm t+e to do a lighting circuitYou think the cable is amusing....I’m off to do the adiabatic! Wait till I post them maths up ha ha ha
Im dying here Tony......you’ve lost me there sorryDo the maths don't forget about the insulation double thickness over and under the cable,will work out you need to use 6 mm t+e to do a lighting circuit
Sorry mate,you the one who used the word adiabatic I thought it was about thermal effectsIm dying here Tony......you’ve lost me there sorry

Need some of the cool Irish stuff. Got some 16mm t+e here, 16mm CPC.I’m just going to remind that 10mm twin and earth typically comes with 4mm of copper for its cpc.
I like it...…...t'b sure.Need some of the cool Irish stuff. Got some 16mm t+e here, 16mm CPC.
