Anything over 16mm Swa you can't use the Armour as the Earth. 16mm Swa armour is roughly 10mm equivalent, You'll be looking at 16mm earthing on that cable minimum!!
@@pault4793 Done it.😁 Maybe I'm wrong on this but I seem to remember this was a question in one of my exams.. There was another question about Aluminium cable for lighting.. Supposedly the minimum CSA is 16mm...🫣 You can verify that if you want, I'm pretty sure that's correct!

good work James on that trench
Quality trenching by the 'hands' of the Hitachi mini digger 😉
Absolutely you dug it by hand...
Because you never said WHAT was in your hand when the trench was dug...
😄😁😆😅😂🤣
Why is the earth separate? Is it cost of the SWA cable?
probably local grounding correct me if I'm wrong but I'd do that
