Hi - I specified a 2.5mm2 T&E ring circuit feeding general 13A socket outlets in two small bedroom and an adjoining hall, 32A RCBO at distribution board. I calculated a 5 amp connected load with a 20mm cable run.
The main contractor is making a fuss about the ring being a 4mm2 one - why is this? I can't see any issues with volt drop of the current carrying capacity of the cable.
