cooker connection to consumer unit

Looks like there would be space for another RCD and an MCB. You could get the board re-arranged so that everything was RCD protected.

I would want the kitchen sockets on an RCD, as this is a room you are most likely to have wet hands in when using equipment.

Isn't the polarity a more pressing problem?

Yes 6mm radials are ok on 32A MCB's.


Do you know whether the CU was fitted at the same time as the oven/new kitchen ?

nothing has been revised since I have lived at the property (4years) both look quite old now, but no I don't know if they were both at the same time.

personally I would check (e.g at the oven outlet) that it isn't a ring.
I know its not a reckognised ring final configuration using 6mm, but i'm also amazed they are both on the same MCB when there is loads of space and what looks like a newly installed cable with the CU.

Or were they saving money on MCB's ? Afterall 3 wires going to one MCB.

Is it the polarity of the rccb that looks wrong? I.e live on left?

i think I'll get someone in to check it all out.

No, the main switch and hence, everything.

neutral on left top and bottom, live on the right top and bottom? is this wrong?

It is if all the MCBs are connected to the Neutral side of the switch.




If you are comfortable doing it _

Can you switch off the main switch,
remove the grey plastic cover at the bottom and
post another picture.

Be careful as the incoming cables will still be live and if something is wrong other things may be too.

In the meantime, while he's doing that, the picture above does indicate N on the left, L on the right.

 

[EFLImpudence]

It does, and so does the RCCB I think, but that doesn't resolve the problem, does it?

I did say in the meantime...

erm, not sure why you are indicating something might be wrong based on what you can't see?
anyway i appreciate your concern, the live on the right top is connected at the bottom to the bus bar, the neutral is wired round to the neutral rail.

 

[EFLImpudence]

That's ok if you are certain but that's an odd way to do it.

it does look odd as the bus is off to the left so crosses the neutral, i suspect whoever installed it was set on following the polarity marked on the switch with live being on the right. i presume the switch is symmetrical so could be reversed as long as polarities aren't crossed obviously.

thanks.
