Hi I've rang the Nic twice about this after a differance of opinion with a friend. Both times the Nic gave me different answer.
Situation. Say for instance you add a socket to an existing ring main or install an extra light fitting to a circuit, the consumer unit is only 6months old is a duel Rcd but not to AMD3 would the modified circuit have to be installed on a new AMD3 board either by changing the whole thing or installing a separate board or is it fine to not change the board.
Would the situation change if you were to run a new circuit of the existing board.
