RCD Protection

[Jimmyb]

If you go to extend a ring main and the board is all covered by a single RCD do you need to update to minimize danger in a event of a fault, e.g move circuit to seperate board (well quoted to move light circuit to seperate board) because i lost out due to cost of doing this and the other company got the job and they just extended the circuit.

It just needs to be rcd protected if the cables are buried in the walls.

It just needs to be rcd protected if the cables are buried in the walls.

And of course if it's supplying socket outlets that are for general use by ordinary persons, 411.3.3

It's fine, just note the single rcd in the 'comments on existing installation' box on your MEIWC

As not making the existing install any more dangerous than it is,could extend or add circuit to existing board.
