have you got 2 or 3 N bars?

Probably easiest to see if Schneider sell high integrity boards. If they do, you just need the busbar from the main switch with two outgoing prongs (one for the submain MCB and one for the existing RCD.

Looks like the bottom neutral bar on the right is straight off the main switch. I'm guessing there's a third neutral bar at the other end of the board for RCD 2.

Bit worrying those uncovered bus bars no?

Split the incomers into 2Henley blocks and feed your new board from them, via an Isolator

why is that??

why is that??

Errr because its dangerous.

why is that??

It's dangerous because some idiot (you) might remove the cover of the consumer unit without first turning off the main switch!
See picture for example

Ann, But how do you know the board is not isolated elsewhere?

On another note the design of the bus at to go around the back of the N on these boards is daft.

Can you put in a separate switch fuse for the sub main? Will save messing about with the board.
