What size main earth if its TT- tails 16mm? I done a eicr- it was 10mm to the rod- it was clipping direct to the brick work and then went under ground for a bit. I assumed it had to be 16mm reading table 54.1 . As there is no mechanical protection on it and goes under ground for a short way. Please can you let us know your thoughts.
Good reminder video on sizes
