Hi,
If you went to a property and the existing board was very old and your new work there required you to split the tails into henly and install new board for the new circuits. Obviously the EC to new board will be 16mm from external MET to new board, MPBC will be upgraded to 10mm from MET to new board.
As your not touching the old board, do you have to upgrade the EC to the old board? I don't think so but wanted to check.
Thanks in advance for any advice.
Cheers
