It should be feed from the rcd side of the board if the cooker control switch has a 13a outlet on it!!!

Well yes TT. Indeed it is a big problem with forums really. It is not possible, when ya think about it, for any non-experienced person or DIYer, to put into writing the data that a pro actually needs. Almost by definition were they able to then they would not be asking the question coz they will know the answer.

PS. Ya have a PM mate.

Depending on installation method 10mm able to carry up to 64 amps but more likely it will be 44 amps for standard installation. So assuming 44 amps thats 10,560 watts - so if ya installing a big 12kW cooker (hob and oven) then rip out that 10mm and fit 16mm! Else a 45 amp MCB will do the trick and dont fit RCD side.

By the way if its an oven ONLY its probably fitted with a 13 amp plug, if this is the case ya need a much lower value MCB and do fit a lower value MCB.

no MCB was suggested it seems, and without the kW you couldnt fuse it correctly anyway, i could have asked when i gave the rating of 10mm, but didnt appear obvious  Roll Eyes

Nobody has asked what rating the cooker is in KW?
So how do we know what mcb is required?

10.00mm T+E is rated at more than 40A but what is the cooker rated at?

Come on lads, pull your socks up here!

aren't JCBs the things you worry about digging through your armoured runs Wink

rcds are not needed on cooker cuircuits and i would suggest using the non-rcd side of your cu especially if the rcd is small

the mcb should be sized to cope with the rating of the cooker and the socket (if present)
