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?

    It is not wise to perform the yank test on an energised system supplying equipment with a continuous earth leakage by design, at least not with the ungloved hand ! You can end up in series with the standing current, and that ignores what happens to the exposed earthed parts  of connected kit.

    A kick is less risky if there is any question .


    are you sure about 10mm^2 - that is is pretty thin - a 5mm stud rod is going to meet that. (Pi R squared etc.) 10mm dia would have seemed more reliable.


    I'd not worry about the thread - particles of sand and soil are scarcely a 'snug fit' to a smooth rod either,and muddy water will deposit dust like mud in the gaps
