Consumer Unit proximity to combustible material

Apostolos

Good afternoon

We are looking into installing a metal consumer unit within a wooden kitchen cupboard.

I was looking through BS7671 but cant find any reference as to how close can the CU be to a wooden surface since the wooden cupboard that would host the CU could be considered as a combustible.

Am I missing something?

Is there anything in BS7671 I have missed?

We are looking at the minimum dimensions that the kitchen cupboard needs to have in order to host the CU.

Thanks

    install the Consumer Unit (metal CU) above the kitchen in a locked dedicated cupboard.

    If it's high up - what's it like for access? Not just for staff resetting MCBs/RCDs but general maintenance - repairs and periodic inspections? BS 7671 has requirements for accessibility (e.g. 132.12) as do more general H&S stuff. Would staff need a ladder to reach? (working at height) or would it involve leaning over from the top of a ladder (because you can't get the ladder closer than the width of the worksurface underneath)?

    I have seen DBs placed in questionable positions in a lot of apartments / houses in the UK. I think the BS7671 regulations need to give a more definite answers to aid safety of occupants & ease maintenance. 

    Placing a CU high away in a kitchen cupboard is just one of the many cases. As an electrical design engineer, I believe a proper review of the apartment would help identify better suitable locations. Look around for some dead space maybe behind the kitchen door.  I would suggest a mounting height of about 1.8Mtrs AFFL to top  frame. A recessed enclosure with locks would be a good fit.
