I plan to have 4 low voltage garden lights supplied via 1.5mm swa which will be switched from inside the house. I have already ran swa from CU to suitable outdoor box which i will terminate and connect 1.5MM T&E and bring through wall inside house to a switch. I have already earthed the armour at the CU is this adequate or is it necessary to earth at the outdoor box also? And therefore earth the armour at each lighting point in the garden?
Thanks
