I'm now considering 3 phase installation from the grid.
Could I use the 2 buried existing 3 core -10mm sq swa cables in combination for the 3 phase supply from the new meter/cu/fuses to a 3 phase distribution board about 6 metres away in a new outbuilding?
i.e. one cable to carry 3 live & the other to carry the neutral and earth.
