Hi folks.

Wanting to do some work on a lighting circuit. Need to change to 30mA protection, currently 100mA S type...
I know the Starbreaker boards can be configured differently with their busbars, but how! See piccy. Is there anyway to introduce another 30mA rccb onto this board, maybe moving the 100mA along to the left...I had a brief look underneath the breakers and the bus bar looks to be continuous all the way across.. As I understand it you can get different sized bus bars but never had to change them before...
I had a look online for info but found little of any use... Any pointers welcomed..

I had the cover off Buzz but didn't take a photo :rolleyes:

The only Starbreaker boards I have fitted have had the MS on the far left.. no idea why the time delayed has been plonked in the middle...

That board has already been doctored. I have never seen a Starbreaker board with two rcds next to each other and as already said the left side main switch is missing.

Yeah thought it had been altered Westy. And thanks for the vid Buzz, not checked it thoroughly yet though as filling in three eics tonight...:(
I am thinking the 100mA might be able to be moved to the left and act as main switch. Then have a new 30mA rccb next to it, whilst keeping the existing 30mA as it is. I could put the lights on the existing rccb but really don't want to if in anyway avoidable. Nuisance tripping etc etc..
BUT I am not sure what the situ is with the bus bar, and whether my plan is feasible... As I say I have only dealt with these boards a few times and have never had to rejig one...

that board must be a TT then ,but the question why would the plant pot put in the middle .
It is a TT Buzz, and quite a nicely done one too with decent Ra. No idea why the s type is where it is though!

why not fit a RCBO to left side of board?

or move circuit over to the 30mA RCD.

RCBOs it will be Tel, thanks. Don't know why that didn't enter my head! Guess I was too busy thinking about moving the main switch and the busbar configuration...
 

Are there enough independent certification companies?
