Hot tubs....

Right to all of those interested I have tried the rod and pme and you get a tingle and now have made the tub TT and tingle has gone, rod is 13 ohms so all good to go! Must be a slight potential difference between true earth so to speak and the suppliers earth, that's all I can think of....

It's not so much the PME, more in the fact that a person with wet bare feet on bare ground or a conductive concrete, that is at or near to true ground potential, with an electrical ground potential also being present. There is a chance (remote maybe) of a step voltage between the two potentials....

The chances of a broken neutral on the PME, i wouldn't particularly consider, you'll be lucky to see one real instance in a lifetime...

That's what I was trying to say lol didnt realise you has already said it
