Does anyone have experience with installing underground primary (13kV) using three single conduit with one phase per conduit. I am used to seeing three single phase conductors in the same conduit. Won't using singles pose a heating problem?
Customer has european design machines and wants to only connect the three phase conductors from a distribution 277 / 480 wye with a grounded neutral transformer and not connect a neutral conductor. Does anyone have experience with this ?
