[QUOTE="Eagle497, post: 552525, member: 37732"] Is it acceptable to over-size the feed cable to a 20A 230V lighting circuit to overcome volt drop ? The circuit would be :- 20A type B RCBO protecting 100m x 16mm 3 core SWA connected to 3 x 100m, 4mm lighting circuits. I know that I could treat the 16mm SWA as a sub-main and fit a small distribution board for the 3 x 4mm circuits but it would be at high level and resetting tripped breakers would be problematic. If the above is acceptable, how should I record the cable size on the installation certificate ? [/QUOTE]
