Bets solution to resolve hole behind ceiling light

Former Community Member

Hi


Sorry if this is quite a basic question.


I am trying to work out the best way to fill in a hole behind a ceiling light. The light is mounted direct to the ceiling and has multiple lamps mounted on arms, my guess is it weighs between 1kg and 2kg. There has been a hole made behind the mounting to accommodate the connections which would attract a C2 on an EICR, I am trying to work out how best to resolve this.

I could put a hole in the floor above and mount a box above the fitting, but this feels like a lot of effort if it's not required.

I could use fire retardant sealant but this strikes me as a bit messy and wont be good for future maintenance


I was wondering if I could use a circular dry lining box but I am concerned about its weight bearing ability, the ones I have found are rated at 3Kg which is enough for the light fitting I have but I think BS7671 requires a minimum of 5Kg?


I would like to know what others would do and if there is a recommended solution.


Thanks


Alan

    I seem to have misunderstood the OP -  do you have a hole you want to fill in because the light is smaller than it is, or are you proposing to make a hole, push some connections in , and then close it again?

    If the latter do not underestimate the potential for pre-wired  deeboxes pushed into a smaller hole like a string of sausages Two long thin boxes joined by flex may be easier than one larger one


    " Dire Risk" is a bit strong for using an inaccessible cavity in the building structure as the enclosure to prevent access to terminals that are already IP20. How can they be touched ?


    So long as the wires are not stripped in such a way that live metal is accessible, then there is practically very little risk to dropping the joint into the void.

    It's not very elegant, but is quite common behind wall lights and so on - and 'tape' is not really a great solution - either it is safe as it is, or else it needs a real enclosure, tape tends to peel off over time, and is the sort of thing causes trouble later.
