Hi guys, I am slightly puzzled about this, if a commercial ground floor shop is to get rewired using a single phase consumer unit and it has a three phase supply but only one phase is supplying the shop and the other 2 phases are supplying different property's upstairs not belonging to the shop or in any way connected by any electrical circuit. Would you just treat this is a single phase supply when documenting this on the EIC or would you say it's a three phase supply?
