Hi, As there is earth wire in a single core form its fine and no code needed. but if the earth is missing and light fitting is metal or class one I suggest C2.Hello all, my question is regards to a eicr. I have come to a property to do a eicr and have come across the lighting circuit neutrals in single insulated with no earthing. The live have earthing, which are single but the neutrals have none. Would this constitute a c2 or a c3. Thank you in advance
