Hi guys, I am designng at route for 5 flats & Landlords mains power supply! The property is 3 storys heigh and two incomers go off on each floor. Just wondered the distances I need to keep the cables apart going up the building. I have found in some literature from our mains power distributor that in the ground the distance is 150mm, would it be the same in a duct? if it is it will be a very large duct!!! and am i right in thinking the mains split concentric is around 20mm in size?
