I am going to do a Consumer Unit change next Saturday and I want to have this as one of my NICEIC assesment jobs. Does any one have any tips that may help me? Its on a TN-S supply and has quite a bit of DIY wiring in the house. Do I have to ammend all the bodge jobs or do I just need to note them on the EIC? Also, do I just do the usual testing before energising the new Consumers Unit?
