Replace a ceiling rose

[AuxDIYer]

This is a light fitting in the lounge, I want to replace this with a six terminal junction box , as I am replacing the existing fitting with a flush mounted light fitting.....can anybody please advise what wires connect where in the junction box?

You don't need a 6-terminal JB, you need 4:

Live
Neutral
Earth
Switched Live

All the reds go to live, make a careful note of which black goes where as they are not all neutrals - basically just replicate the existing 4 terminals in the rose with the JB.

thanks for the quick response..will try that and let you know if I was successfull with it.....

as an aside on this ....the new light fitting has a connector block mounted in it for L,N & E....could I not just connect the relevant wires up to those blocks, then place the remaining wires into a connector block, insulate the block, then slide it into the ceiling space, rather than install a junction box in the ceiling space?

Any comment on my idea?

Yes, you can, provided there is room in the terminal block of the light for all of the cores.

Remember, the "L" on the light is for the switched live - the permanent lives are the ones to go in the extra terminal block, and also note that that terminal block should go in a small box, not be left exposed, or wrapped in tape.

thanks for the response...was thinking of putting in a choc box, not just wrapping in tape and shoving into ceiling

Also, note the red marker on the switch wire. Although the picture shows it red you should now mark yours brown both ends

 

[ban-all-sheds]

I disagree with that "should"....

 

[Pensdown]

Quite correctly it should read as follows;

Also, note the red marker on the switch wire. You must have this on both ends to identify it as a switched live and not a neutral. Although the picture shows it red the colours have now changed and you should be using brown instead.

Now you're confusing me, if the wiring is in the new colours you should use brown sleeve, if it is still in the old colours use red sleeve.

 

[Pensdown]

Are you sure about that? I've been lead to believe that as the old colours no longer exist any alterations to existing should be marked with the new colours, even if no new cabling is being installed.

It'd seem to make sense to use red if the old colour scheme is in use, but if you can only get hold of brown, its obviously preferable to ommiting it all together

(not sure where the regs stand on this though)

I thought it is meant to be old coloured cable = old coloured sleeving, new = new. Otherwise you could end up with a 'red and brown' cable at a switch. If you haven't got any red sleeving and can't get it use red tape. You can still get that. Personally I have about 200m of the b****y stuff. (Lost my coil, bought a new one, found the old one, then the colours changed!)

I would agree old colours = old colour sleeving

 

[Pensdown]

Don’t get me wrong, I totally agree that matching colours to the existing installation makes complete sense and I’ve got enough cable & sleeve for us all! But I’m sure I have read somewhere quite recently that brown sleeve must be used on the existing cabling when carrying out modifications which is why I wrote should
