Hi james,
Not done to much aggricultural myself, but i know there is probably a few things you could change. The 32a mcb for the lighting, knock it down to a 20a type c. Your gonna need some rcd protection on the new cu(fire protection) think its a 300ma and additional rcd protection on the s/o 30ma. I would Up the 10mm to a 16mm for future loading because 10mm only holds a current carrying capacity of 67A clipped direct and 16mm is 89A best to be safe. Oh and make sure all your earthing arrangements are satisfactory. Hope that helps
Hi
20A type c mcb for 10 400w sons will that carry the start up surge ?
