[QUOTE="binky, post: 461686, member: 490"] Just wanted to check Rob, I don't do much 3 phase work, so I'm a bit rusty in this area. I've got a customer who tells me he needs a 20kW supply, but somehow has got in his head he wants a 63A socket on a 63A MCB and cables to suite 63A per phase. (I think he is confused) Now 20 kW is roughly 80Amps, cable run is 45m clipped direct to wall. Now rough calculations would suggest a 6mm cable would suffice for the load. I am planning to install 10mm, table 4E2A says 71A (total) for 4 core. THe load is to charge batteries, so I'm working on the basis the load will be quite steady for quite some time and larger cable cost will be outweighed by reduced energy loss and wasted leccy. Now if what he really wants is 20kW per phase, that's a bit of a larger cable :^O batterys [/QUOTE]
