Volt Drop

[Phaze-3]

Hi guys,

Need to put a 32A 3phase supply in to a 10KVA site transformer using swa. The run is 250m long but would i need to apply 3% or 5% volt drop??

It works out at 3% i need to use a 35mm cable and at 5% i can use 16mm.

Anyone have any idea???

Thanks

3% for lighting and 5% for power circuits -

as above post - do your cable calcs !
