[QUOTE="Normanw, post: 466363, member: 30347"] How do you do a Ze test on a TT system? The issue appears to be that the supplier says he has a good earth at the supply transformer (500yds away) by his test (<0.7ohms) but I don’t understand how I prove that I have a good earth on my earth rod compared to the supply transformer earth.
