Hi all,I found a 6mm “cooker” circuit feeding 4 sockets in the kitchen as a radial. R1+R2 tests fine and Zs is low. Can’t see where they are jointed but it goes from 6mm to 2.5mm. If everything tests fine, can’t see a problem leaving it as is. Will have to downsize the mcb as it’s currently on a 32. It’s an old apartment within a block of apartments, probably 60’s built. Shows no sign of thermal damage etc. Can anyone see anything wrong I’m missing? What should I put on the paperwork for the conductor sizes? Many thanks!
