Btw thanks to the chaps who have advised me in a constructive way!
Looking at a job and explaining it is one thing, reading an explanation and trying to form an imaginary picture to be able to offer safe and sound advice is completely different. Now this is fine when it comes to jobs such as building a timber frame or putting up a picture frame but what you need to realise is that from an Electricians point of view it is impossible to offer sound advice without having a CLEAR understanding of exactly what it is you need to do. Diagrams or photos are a massive help but rarely posted
You've specified no location ie kitchen/bathroom WHICH ARE BOTH NOTIFIABLE BY LAW, or if there are additional factors to consider such as insulation in a loft etc.
Also there is no description of the units being installed, for example some areas require particular ratings to make them suitable in different circumstances.
Whilst it's nice to see that you have considered the risks and just want to be sure, to me it sounds like you should ask a local spark to pop over to assist. I'm sure if you posted up your location a member would happily take the time to pop over and assess the situation for you.
Another point I must make is this, you are making an alteration to the circuit therefore that particular circuit will need to comply with current regulations (even if it is not notifiable by law). In order for it to comply the circuit must be protected with the appropriate cable, OCPD and 30mA device and there will need to be specific tests carried out on the circuit and installation to ensure that any alteration/additional work has not compromised the integrity of the circuit. Also bonding conductors to gas water or extraneous parts may be required or need to be upgraded.
Please understand that the forum attracts many DIY associated questions and SOME are clearly out of their depth and should not be anywhere near electricity. It kills if left in the wrong hands, maybe not today, maybe not tomorrow.
Some faults may not rear their ugly heads for some time down the line which could result in death or serious injury by cause of fire due to a simple electrical job not being carried out correctly.
Hopefully my input may help to assist you understand why you have received some of the less helpful posts in this thread.
As for the question, Ceiling roses are designed to supply one pendant only. If you want to supply more lights then you will need to install the appropriate junction boxes keeping in mind that they should remain accessible for inspection/maintenance purposes. If floor boards etc are placed over them afterwards then this is not accessible and maintenance free enclosures will be required.
What seems like a simple task for a DIY'er who is more than capable of carrying out the work is a lot more involved for an electrician who HAS to undertake such work ensuring that all the correct materials are being used, all cables are selected and erected correctly and all work inspected, tested and certified at the end of it.
Kind Regards
