OP you will need to provide some details about the type of swa used (pvc or XLPE)
OP you will need to provide some details about the type of swa used (pvc or XLPE) and how the cable has been installed. You say 'free air' which is a reference method in BS7671, not a term a layperson would use?
Sorry if this is not the correct wat to post my query, I am new to the site. I am not a spark but would like to tap into the skills and experise on here before I set off on the wrong course with my current spark. I am having a garden office built, it has had its own CU installed but my ex spark neighbour came round to look and has caused a row with my spark by saying he was incompetent and had done it wrong. I'm confused and don't know who to believe.
The new cu is fed from house via a henley block with its own 100amp isolator. The CU in house is on a mains fuse of 100 amp with 25 mm tails.
The issue is the cable used to the garage, it is free to air, 15 m long and swa 16mm 3 core cable. 1 of the cores has been used as earth, so my spark says its 2 core single phase system which can carry 115 amp.
The room will sometimes draw 70 to 80 amps as has an electric 9.5 kw shower, sockets and lights.
My neighbour ex spark has disagreed and says 'in his day' it would be on 25mm cable. Is my house in danger or is my spark complying with current regs?
