I have bought some down lighters to replace my existing kitchen lighting, however the new downlighters have no earth connector inside the fitting, i was told i must follow the earth through, how is this done? and where does the earth terminate, incidentally the downighters are on there own lighting circuit

Many thanks

Are these 12v or 230v downlights.? Decent 12v transformers have an earth termination to facilitate the earth connection. If is 230V and theres no earth connx then use a 5A terminals block at each light like this:;j...YCSTHZOSFFY?_dyncharset=UTF-8&fh_search=18802

At the end of the run you will use the earth there to check the Earth Fault Loop Impedance to confirm that the fuse will work!
Are you sure there isn't an earth connection point? It may not be with the phase and neutral terminals.

Fair enough. the lights do not need an earth, but the electrical circuit does!

Assuming the switch wire and neutral is only feeding class 2 downlights then why does the circuit need a CPC? It's only the switch wire and neutral we're talking about isn't it?
The switch must however be earthed if the backbox or faceplate is metal.

Personally I would terminate into 20A 4 terminal junction boxes but a CPC isn't a must in certain circumstances.
