Induction hob correct install

[Burnmenot]

I’ve been looking for the right answer and just can’t seem to find it.
I had an induction hob installed by a certified electrician, and there are no apparent problems so far, however, it is installed on the CU, RCD and upstream with a RCCB with no MCB,
I’m just not 100% sure if it’s the safest way to install it, I would personally think that would be safer on an RCBO or on a MCB, I’m not worried about overloading as it’s on a 10mm2 cable, 40a RCCB and the unit draws a max of 25Amp, I worry more about the fact that the RCCB will not protect on short circuit.
I appreciate any feedback or comments.
Thanks

Can't be certain but it appears the RCCB is fed from the top left 32 amp MCB.
That board is a bit of mess to say the least.

Thanks for the comment, yes not state of the art.. it’s a 20 years old CU. The RCCB is feed from the busbar from the RCD as all the other MCBs on the busbar, I think there is no problem there. Question is about the RCCB being safe or not without an MCB.
Thanks

that whole board is a complete disaster. wants scrappingand a decent new board installing. don't use the same electrician. seen better jobs done DIY at a Gypsy site.

What does it say about protection device in the installation certificate?

As Delroy would say

NO WAY , NO WAY WAS THAT INSTALLED BY A QUALIFIED ELECTRICIAN

In that case, the circuit fed from the RCCB has no overcurrent protection.

Sure you have the right unit indicated, the F&G Moeller B40 FL7-40/N says its an RCBO just under the red indicator window.

Indeed it does. But it's not the one under discussion, ie the one with the 2 big arrows!
That one is a 61008 RCCB without overcurrent protection.

 

[Mike Johnson]

Sure, but as there is no cable identification who knows what any of the units are protecting, only way to be sure is to switch one off and see if the hob still works.

 

[telectrix]

if i were switching any of that mess off. i'd use a pool cue.

OP, what made you look at how the electrician had wired the cooker into the consumer unit?

Did you get an installation cert?

And yes, fundamentally every circuit needs over current protection of some sort.

certificate? lol... don't get me started...

well, apparently he was a qualified electrician...

thanks for confirming that, I take it's not up to standards or even safe then?
