Was working on an installation a few weeks ago (PME domestic) which had a sub to a garage which in turn had another sub which supplied a c/u in a shed about 20 meters down the garden.
Got talking to mate of mine on Saturday who said that both the subs should be protected by an an individual earth electrode?
This got me thinking that I'm sure I did read not so long ago, can't remember where, that the means of earthing on a PME should not be taken out of the equipotential zone, exactly what my mate had said?!
He didn't seem to know why, we both stood in the middle Morrison's both somewhat confused?(nothing new there)
I can only assume that this has something to do with the declared Ze only being applicable at the customers intake only?
Advice appreciated!
