Adding and RCD

[davy_owen_88]

First thing you need to do is to determine what all the breakers are for. As coljack has already mentioned, the 8 MCB's to the right are RCD protected but some may be able to go on the non-RCD side. This may reduce the load on the RCD to safe levels.

Is it just me or does the insulation on the neutral going to the bottom right of the RCD look heat damaged? Looks pretty shiny and creased to me.

this would involve new busbars as the old ones have been cut to suit by the looks..
