Changing a consumer unit at a flat but have a few questions regarding earthing etc. supply is from 16mm T&E fed from the incoming supply cupboard in a separate building main supply is tn-c-s. Each flat is supplied from a 63amp switch fuse. So earthing to the flat is via the 6mm back to the switch then 16mm back to main supply ze measured at 0.16 at switch and 0.20 at CU.
Flats are bonded in 6mm.
What are regs in regards to bonding from switch tto board? Being a TNCS should it not be 16mm back to supply? Only trouble being its impossible to do this?
I haven't done many changes in flats and wondered what the ddeal with supplies as regs?
Thanks Ian
