Creating Loop In using connection blocks

[frank999]

Where Ceiling roses are not being used, but the light fitting has just a two wire connector, do Regs allow the use of ordinary connection blocks or Wago's, placed inside the lights casing.

I see the loop in has been created behind light switches in other parts of the building here using ordinary connection blocks.

The Below light fitting has a metal casing, the earth wire will need to be attached in this instance ?

It is an interesting question, I have always treated the light casing as a ceiling rose, but not to BS 67, however it says:-
(ii) A luminaire supporting coupler to BS 6972 or BS 7001
(iii) A batten lampholder or a pendant set to BS EN 60598
(iv) A luminaire to BS EN 60598
(v) A suitable socket-outlet to BS 1363-2, BS 546 or BS EN 60309-2
(vi) A plug-in lighting distribution unit to BS 5733
(vii) A Connection unit to BS 1363-4
(viii) Appropriate terminals enclosed in a box complying with the relevant part of BS EN 60670 series or BS 4662
(ix) A device for connecting a luminaire (DCL) outlet according to IEC 61995-1.
I would not expect the casing has those makings so technically I suppose the answer is no, I suppose you should use something like the Hager J501 which complies with BS EN 60670-22, but personally I would not worry, I would treat the enclosure same as a ceiling rose.

Yes I did have a problem with my father-in-laws light at top of stairs where the metal cover had touched a strand from a live wire, I am sure if it had complied with one of the above standards it would have had a plastic cup inside the metal outer, and I suppose being pedantic one could fail it on an EICR, but some times we need to use common sense.

Shouldn't this trip at the consumer unit as all metal fittings I have seen are connected to earth?

Yes the metal cover should be earthed, but one strand of flex cable will not take out a 6 amp fuse, and likely there should have been an inner plastic dome which would have stopped anything touching outer, but father-in-law was electrical clerk of works for Liverpool Hospital Board and had a notice on his desk saying "These people who think they know it all, are specially annoying to those of us that do." Have you ever tried to tell some one like that at 90 what he has done is dangerous?

He got me to fit RCD protection to all circuits in my house in around 1992, but his own house still had Wylex fuse box fitted.

It is all too easy to tell some one it should trip out when you have RCBO's on every circuit, but not everyone has RCBO's on every circuit. Jumping to conclusions can be dangerous, I could have easy answered this post saying simply if you don't know you should not play with electrics. But when one sits back and thinks about it, then not such a daft question, specially with the EICR for rented property raising many items as C2 code faults which we would for years never even considered as a fault.

Thanks, this makes one wonder for what purpose are connection blocks ?

So where does the use of Connection blocks used in light switch back boxes as the loop in/out lie with the Regs.

I have always treated the light casing as a ceiling rose
Is that where the casing does not contain an included manufactured loop in loop out connection block, and you have added those connections inside the casing, as I am suggesting doing.

There is nothing wrong with connector blocks in the light casing or fitting.

That is what is supplied in many new lights.

That is excellent news. Thanks.

I couldn't see any reason why they wouldn't, but the more experienced here might have had a Regulatory reason up there sleeve, but it appears not.
