[QUOTE="Sponge bob big pants, post: 504881, member: 33414"] Hi All, I am very rusty on cable calculations as I haven’t really needed to do it very often and kind of need a bit of reassurance. I need to supply a 3 phase sub board, 45 meter run in a duct from one switch room to another. main supply is 100Amp Sub board is a 3 phase 100Amp main switch I was thinking I would need 35mm SWA 4 core with 20mm separate earth. Does that sound correct. Any help is appreciated. [/QUOTE]
