One of the questions on a recent Part P assessment was how would I wire an external outbuilding if the earthing arrangement to the property was PME.
I said I would run a three core SWA from the property to the outbuilding and use the cable armour and the third core as the exported CPC.
I was highly criticised and was told that I should install a rod at the property and at the outbuilding.
I can find no mention of this in 17th ed AMD3 book, can anyone tell me where i would find this if it is the case.
I have had a couple of other Assessments previously where they have checked out building installs and never mentioned this so I am not happy.
