I have several vintage lamp holders and would like to use them because they have a good look. I found these earth tags (Earth Tag For 10mm Allthread Rod [PLU95920] - https://www.lampspares.co.uk/earth-tag-for-10mm-allthread-rod) and wondered how to attach them to my lamps for them to work. Is it safe to place them inside the lamp holder under the fitting with the live and neutral wire - I would need to bend the earth tag a bit - but would this risk crossing wires?
