That is a 16th edition consumer unit,you should be using a 17th
edition which has two rcd"s.

Seems like you don't have enough MCBs for your circuits.

 

[telectrix]

buy some RCBOs for the non-RCD side.

Main switch?

You need a main switch and 2 rcds, is that what you mean?

If you fit an RCD main switch, all circuits are then on 1 60A RCD.

Kind of a moot point but if you end up with the right Consumer Unit and it has two RCDs I'd put immersion on one side and central heating on tuther.

But so far the signs are not good.

Where you based? It might be worth getting a look in from someone if only for a corrective tightening of your sphinacker to avoid tacking off course.

Sorry worded that incorrect , yes it is a 80amp main switch feeding 2x 60 amp RCB one for each split .

To be honEst Ive gone reet off dual rcd boards. Started just using Rcbos only, cheap now, and you get more circuits in a board.
