want to replace existing ceiling rose with downlights

Postby ma » Mon Mar 14, 2011 10:45 am

existing wiring as follows for the bathroom.
a have two main switches outside the bathroom door and one cable goes to centre light, which i gather acts as a ring main, cause it has a cable going to the hall light and bedroom. then another cable from this centre light goes to another centre light in bathroom, which has a cable going to kitchen lights, extractor fan and to a juction box. another cable from this junction box goes to the second main switch.
I now want to do away with the centre lights and put 3 mains down light instead which has a connector block connected to them with live and neutral wire spacing only. How would i wire these 3 together to run from the one light switch? I presume i would have to wire the others into a choc block or jucntion box, asis the wires in the centre light? what amp jucntion box would i need and is 1.5mm cable good enough for the job?
sorry im a novice but understand a bit.

Simply Build It

There are diagrams in Projects on how ceiling roses are wired but by time you have informed LABC what you want to do and paid their fees of a £100+ and hired a loop impedance meter to fill in paper work at another £75 then likely it will be cheaper to get an electrician to do the work.

You will need L N and E for the new lights and this you can get from the existing central light. Rating is not a problem and 1.0 T&E will do.
Read up on zones in a bathroom and bear in mind that this is notifiable work under Part P.

this is probably no more than a morning's work for a qualifiied spark. as it is notifiable under part p you'd be better off getting a pro in to do it.
