Adding Additional Lights.

[Tueur]

Afternoon all,

Just after a quick sanity check on what I am proposing before I start. my landing and stairwell is L shaped and I currently have one ceiling rose hung on the right angle of the L. There are switches top and bottom and it is wired up using the attached method. I am want to replace the ceiling rose with a double insulated spot light, add an extra spotlight on the landing end of the L and then a new ceiling rose with chandelier at the other end of the L in the stairwell.

My plan is to replace the existing rose with a junction box in the loft and terminate switch and lighting ring in the junction box. Where the diagram shows "to lamp holder" i will run twin and earth that to a second box and then wire each light fitting to that box.

In theory I could run all the cables from the one junction box but there would be too many cables terminating in the one box.

Hope this makes sense?

Thanks

Makes sense, just make sure the junction box is either accessible, or a maintenance free one.
Also your spot lights make sure that there's no extra air leakage into the loft as partly it will be a waste of heat and partly there will be additional condensation risk from the warm damper internal air.

There wouldn't be if you used a junction box with enough capacity for all the cables.

Make and type please BAS

Sorry - Wagobox XL (to take the new 221/2273s, - if you happen to have a stock of the older types of connectors the XLA accommodates those.)

Ummm.....

BAS Can you let me know the brand and type of that junction box. I have an applocation for which that box could be ideal.

Regards

Bernard

Hi All sorry for the delayed response.

I have got this all wired in and working perfectly. Thanks for the input/advice.

Top stuff as always!

Lighting is not wired in rings. It uses radials.

It does indeed - but why have you popped up with this information 6 weeks after the comment was written?

Kind Regards, John

Because I only just saw it.

Hibernation over? Metamorphosis? Maybe he will transform into a new beautiful being.

There is nothing wrong with lighting being on a ring final. It may, in a large house be advantagous, when one considers voltage drop ( 2.5 mm² doesn't fit well in the average ceiling rose )

Sure, there's 'nothing wrong with it', electrically, but there is rarely going to be any point, even if one wants to stick within the 3% guidance for lighting circuits. Even with a full 6A load all at the end of the cable (extremely unlikely) you could have about 40 metres of 1.5mm². My house is very large, but the lighting circuits are all fairly short, originating at distributed CUs which are fed by 16mm² cable.

The primary reason for the sockets ring circuits is, of course, the dispensation in the regs to use a cable of lower CCC than the rating of the circuit's OPD, but that is not a consideration with lighting circuits (with their 'over-engineered' cables). A ring does provide CPC redundancy, but that's a minor issue for a lighting circuit.

I wonder if anyone has ever seen a ring lighting circuit in a domestic property?

Kind Regards, John
