[QUOTE="binky, post: 558711, member: 490"] Looks like you have an old VOELD below the board, an early form of RCD that I doubt will still be working properly. I would agree updating the board would be a good idea. You could add an RCD in a separate enclosure next to the board for the new circuit, but could really do with RCDs on all the socket circuits, and these days we RCD all circuits anyway. By the time you've done that, it's easier and neater to change the board itself. We also have no real way of testing the MCBs are still working correctly, and after 40 years, I doubt they are. So again changing the board is recommended. But if money is too tight, you can install a new circuit with an external RCD. Earthing and bonding will almost certainly be undersized as well, again, another reason to recommend a board change and update. Note is say recommend, it's not actually compulsory untill you install a new circuit, because anything new must comply with today's regs. [/QUOTE]
