[QUOTE="ProDave, post: 519601, member: 6969"] A picture would make it clearer, but this sounds normal to me. They use a large cable, in this case 95 square mm for most of the run, that is laid in an open trench, not in ducting. Then just before it goes under the building there is a potted junction in the ground and the last bit of thinner, 35mm cable goes under the building in ducting to the service head. So you don't need to dig up your block and beam floor, that bit stays in the ducting you have already laid. Chances are you only need single phase, but as 3 phase is available I would take it, it future proofs you for e.g. multiple EV charging points. [/QUOTE]
