Wiring a new metal light fitting

[enemjay]

Hi all


I have removed standard plastic light fitting and found 2 wires in the ceiling. One is l, n, e and one is switch live, l, e.


How do I connect to the new light that has terminals for l, n, e?
Keep the live 'loop' wires separate?

Shall I buy a junction box of some sort?

Thanks

Live feed and switched live joined together into a small connector block housed inside the new light fitting. The return leg of the switched live to L in the fitting and N from the live feed to N in the fitting. Obviously the earths all go together to the E terminal.

Can you help me out with which is the return leg of the switched live?
The blue with a brown sleeve?

That is the usual convention

Whilst we and the OP understood, that description leaves a bit to be desired

Having followed this, can you help with why it is tripping the RCD when switched on?

"I have removed standard plastic light fitting and found 2 wires in the ceiling. One is l, n, e and one is switch live, l, e."

Do you have two flat T&E cables at your old fitting? If so then the following is the correct method.

If you have the two browns, (reds), terminated into a separate connector block and one blue, (black), into the L terminal of the fitting and the other blue, (black), into the N terminal of the fitting then the connection is correct and there is another reason for the RCD tripping. You may have a nick in the insulation of one of the wires and it is creating a short somewhere or there could be another reason. There may possibly be something wrong with the new fitting.

The A Team use twin brown.
