Working on supplying three phase power to a new shed in a farmyard. Running armoured underground. I was going to connect the armour to the earth rod at the Main DB then use the armour at the other end in the new shed as the earth in the new shed, bonding all extraneous metalwork to it. Is this acceptable or do I have to use insulating gland at new shed end and new earth rod there? Some confusion, as all existing outlying building have no earth rods of their own, just rely on cable armour back to main earth rod.
