I am currently planning on changing the Consumer Unit in the Boiler Room of my home. The board is 17 years old, fitted with old cartridge fuse holders. I am planning on upgrading to a new amendment 3 (bs7671 - 2015) standard. The problem I am having is that I have no experience of working Live, the incoming tails from the meter box have no means of isolation. They are connected into Black connector blocks just before the Consumer Unit and then doubled together in both connectors and are connected on til 2 80A RCD's. If I can get the tails safely isolated, I know how to do all the rest.
Can anybody here advise me on what my safest option would be to give me peace of mind?
