WWilts Posted June 16, 2022 Share Posted June 16, 2022 New build in progress. 3 phase cutout & meter (PME) installed in kiosk about 15m from new build. Rigiduct buried in trench, runs from kiosk to near new build. Intention is to wire house in 1 phase but have 3 phase available in house for future proofing Q. How to get electricity to the new build house? ie what specification cable to pull through the duct? Assume complete ignorance here please.

ProDave Posted June 17, 2022 Share Posted June 17, 2022 For 3 phase you want a 5 core steel wire armoured cable. 16mm absolute minimum if a short run but 25mm would be better. It needs feeding at the kiosk with a switch fuse, 80A to discriminate from suppliers 100A fuse. Best terminate the SWA in a large adaptable box in the house, so you can take a single phase to a consumer unit and have the others terminated for future use. 1 Link to comment Share on other sites More sharing options...
