Electricians: strain relief for ceiling rose fitting

Andrew J
Andrew J over 4 years ago

I‘m busy working on the house at the moment and have found this in one of the rooms. 



As you can see, the whole fitting doesn’t seem to be properly supported and the wires themselves are fraying.  It would seem that there is a lack of strain relief in the way it is wired in.  Not being an electrician I’m not familiar with the best way of doing this given this particular rose fitting.  I can re-wire the live and neutral wires but there doesn’t seem to be anything within the rose itself to help avoid a repeat problem.  Any experienced electrician have any tips (UK based so only ideas that are UK legislation conformant!)image

    I don't think that you are using the cable restraint correctly. ( Always refer to the manual ! ) Heavier light fittings expect the use of a separate hook to take the full weight of the fitting, leaving…

    These fittings seem quite common - and you can still buy them so I guess they must be OK. I've never seen a maximum weight specified for the lampshade. There isn't much risk - if a wire breaks the light…

    "...There isn't much risk..." I think that depends on the size of the chandelier... ...combined with the weight of the person swinging from it at the time of collapse.

    Hi Andrew J

     

    That fraying of the conductors isn't because of the strain relief route not being quite right. IMO it was damage when someone parred the outer insulation back - probably with some pliers - or held it in pliers to strip the ends?

     

    Apart from that your photo is typical wiring for most of these ceiling roses, indeed yours is a bit neater as there is no chocolate block going to another circuit or PVC tape wrapped around an odd wire image. Such a  setup seems to hold a 'typical' shade and bulb...although the glass LED bulbs can be heavier than the old BC filament bulbs.

     

    Something I had years ago was a horrible fishy smell appearing after the (in those days filament) bulb had run for about 10 minutes; it turned out emanated from the old Bakelite fittings. Replaced them one by one with new quality fittings and all was good.

    You’re right - I disconnected it to check and the strands aren’t damaged, just the insulation which has a neat cut in it.  I’ve re-connected it as per Dave’s image so it should be more secure.
