An inspection is just that, not remedial works. Has anyone ever seen a back box with two adjustable lugs on the same plane ? I never have so a bond to the box is not normally necessary. Although this has been mentioned many times before and this is not the right placeI bought a 50metre drum of 1.5mm single earth wire. You can get to one end of the run as they wrap it into the centre of the drum and the other end is on the edge of the drum. I also use it to bond the back boxes on PIR inspections instead of stripping down some 2.5mm
