Hi all got another question for you all, as you no im about to have my assesment by napit,, im thinking or rewiring my garage to be nspected on.
the garage is fed from main CU on a 20a breaker in 2.5 t+e then to a thru box were the armoured it terminated and goes underground to the garage.
Instaed of using the armoured cable as a earth they have run a 3core swa and used one of the cores as an earth. I have just been reading some threads on exported earths, my earthing system is pme, the cable supplying the garage is rcd protected from the cu in the house but just a normal 3 way cu in the garage.
If i rewire the garage for my installation to be tested on is the exported earth going to crop up??? is it an exported earth, im thinking so from what ive read.
i would say the swa run to the garage is about 15m in lenth.
all help appreciated cheers
