RCBO for old MK board

[Crlclarke]

Hi guys
First post so go easy on me!!

Im trying to put an RCBO into an old MK board. I am gonna double up the lighting as its all on LED bulbs and use the space to add a 40A RCBO which is powering a 2 way in the shed. Now im not sure if i can use the modern RCBO's in this board.

Ive seen this one Space does not seem a problem:

MK Sentry 6937S Single Module RCBO, 40A, 30Ma | eBay - http://www.ebay.co.uk/itm/MK-Sentry-6937S-Single-Module-RCBO-40A-30Ma-/201683672920?hash=item2ef5489f58:g:BtcAAOSwMgdXwu6Q

Ive attached a pic of the board

if you're using SWA to feed the shed, why not RCD at the shed? and i hate spaghetti.

How can people make such a mess of installing few circuits.

New rcbo will fit but I agree with Tel fit rcd at shed. Me personally would not double up circuits, nasty practice. I would suggest upgrading the CU.

If you double up the lights and are later asked to do a EICR it won't look very good.
What about the new ring main with no RCD protection. With price of MK rcbos looks like a new board to me.

None of them circuits were added by me!!

The shed has an RCD in it, but do i not need an RCD to cover the SWA to the shed??

Sorry never thought for one minute it was your work. No you won't need rcd assuming the earthing system isn't TT.

Yes. Consumer unit on the right is economy 7 (unused) and the bottom one has 2 fuses in use, not too sure what they are though. Both have a single circuit connected
