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

    weight issues are best solved with bits of roof batten to spread the load, or ideally  to pick up on a nearby joist. The batten can be screwed into to hold it still in a place that later the fitting covers the screw heads, The fitting then screws to the batten, sandwiching the ceiling board.

    Dry lining boxes on thier own  are good for light (weight) fittings or when used with cover discs for joints you need access to, but unless you are very careful to make the hole very snug, it is easy not get the full load bearing ability as a retro-fit in an existing ceiling.

    PS the roof batten idea, pluss a bit of wire through a very small hole in the middle can be used to hold a plasterboard patch in place while you screw it if you need to lose a hole in the middle  of a large panel completely. Here you drive the screws into the plaster board (both the main panel and the patch) deep enough to be able to fill over the heads. Once the screws in  place cut the wire and push the stub into the void and fill that hole as well as the seam and the screw heads too.
