[QUOTE="Andy™, post: 70171, member: 2012"] If you have TN you should see the earth at service head. if you have TT, then there may or may not be a rod. a count of earths leaving board should tell you if there is a rod or not, along with checking connection on gas/water (to make sure its not one cable to rod, one to gas/water looped). if you cant find a rod, you could test earth loop to unknown cables, and remove earth connection from gas/water. then it should give no reading on those, and if your left with a earth rod type reading, there is probably a rod somewhere with TT and bonding in place, it can be almost impossible to tell if there is a rod or not by an earth loop at socket etc (obviously if you get a reading of 1500, there is a problem somewhere) [/QUOTE]
