cooker connection to consumer unit

[nacnud21]

It does look odd, but I don't think it's possible to be completely sure one way or the other without a photograph with the busbar cover removed.

i'm completely sure, as explained previously I looked with my eyes and the bus is off the positive, but if it helps put this to bed and direct the attention to the enquiry first raised ill photograph later and upload

Are you happy you know what you are doing from your initial enquiry?

Its all been an interesting learning curve, the initial question of 'is it incorrect for a mcb to share a kitchen radial circuit and a feed directly to an oven' the answer appears to be clearly no, an individual mcb for the oven is recommended and is preferably rcd side of the consumer, which all makes sense. thanks for everyone's input.

Although not to the rules it's better to put the sockets on the rcd side
And oven on non rcd side.

The entire installation is reverse polarity, one of the most dangerous faults you could have, and needs to be sorted by a competent electrician without delay.

is it?

Either the main switch could be marked (and made) the other way round or fitted on the left.

As I think you're probably implying, it's not just a question of marking. The switch would probably also have to be 'made' differently - since many (most? all?) main switches have 'make neutral first, break neutral last' functionality. One therefore cannot (should not) just 're-label'!

Kind Regards, John

Yes, quite but no real need as it should be on the left of the CU.

However, I think that the installer of this one has gone to some trouble as, perhaps, the tails would not reach the left.

Presumably whats happened is the manufacturer designed a main switch to be placed at the left of the CU, then the trends changed and they wanted to place the main switch on the right of the CU. So they solved this by putting a joggle in the bus bar to send it around the neutral, rather than design a new main switch.

Quite so ...

I would guess that the same manufacturer does (or did) produce CUs with the switch on the other side, and didn't want to go to the expense and trouble of having to produce a different switch for use on the right!
