Single RCD board - changed to dual RCD board?

[highspark]

I want to encorporate an extra RCD into a single RCD board as you will know my problem is the neutral bars. In the present single RCD board there is only 2 neutral bars. If I was to change it I'd need to split one of the neutral bars into a 3rd for the outgoing neutrals of each RCD? Would this be bad practice in your eyes lads? It's either a separate dual RCD board. Or A small garage unit. Or split one of the neutral bars

Hi High spark,

If you split the neutral bar, how would you fit/attach it in the board? Can you not use the other neutral bar (non rcd side) and any circuit on that bar, put on the new rcd? Or is it being used?

Cheers

Jay

Can't do it mate because both outgoing neutrals from both RCD's will be on the same bar an it will cause problems back currents etc

If you don't need any unprotected ways then just protect the other neutral bar with an additional RCD is what he's suggesting.

Run additional neutral tail from RCD 2 [output side] to neutral bar 3.

Thanks, but it wasn't a serious question

Most boards have little plastic contraptions to click the earth and neutral bars in place
Its a simple job if you get a spare bar,shorten them all to suit, and another clip it in thing

Topquark has given the same advise that I agree with
Rcbo

Job hits to be done tomorrow, already thought about rcbo's couldn't get Ching ones in time. I'm going to have to split the neutral bar
