Earth Electrode Concern.

Zoomup
I was working in a large back garden today. The garden shed was connected to an old caravan supply (caravan gone) and the underground S.W.A. cable from the house had been  converted to TT earthing originally for the caravan and now for the shed sockets and lighting. As an earth electrode somebody had used a length of  10mm galvanised threaded rod (studding). What are your views about its suitability please?

    Galvanised rods are common in some areas - I've a feeling that the Irish regs prefer them over the copper clad ones we usually use (I think there was a suggestion that they lasted better in the typically peaty acidic Irish soil). There's a risk the protective coating could have been damaged during driving (but presumably there would be some of that risk with copper clad rods too). So I'm with Andy - if if checks out physically & electrically I wouldn't worry about it. (It might however suggest "improvisation" might have been employed elsewhere on the installation as well - which may or may not have been so successful).
