    Just need some advice on this. Got some new downlights for kitchen to replace ones with heat damage.
    New ones are wired for an earth wire. No earth wire in old ones.
    Do they need earthing?
    Old fitting is a 12v
    New one is a 240v gu10

    Looks like your older ones were low voltage and your newer ones are full 230v.

    Seeing as the casing around them is metal and they are sealed I'd imagine you'll need an earth wire ran, im sure more experienced elecs in here can advise further.

    You can get double insulated gu10 fitting s pretty easily

    There should still be a cpc run to and terminated at each point though, even if the current (excuse the pun) luminaires don't require it.

    Obviously the luminaires in the picture do require earthing as they contain exposed-conductive-parts.

    is there an accessible joint with a protective conductor near the downlights?


    depending on the age of the installation it might not be there


    i prefer to see a lot of this 230v stuff with the CPC connection tbh

    Are your sure there is not a junction box pushed up into the ceiling with the flex going into it.
    Sometimes the trafo for the 12 v comes pre wired with a 2 core flex and then a coffin JB is used with twin and earth jointed to flex.
