Wiring a replacement PIR lamp with permanent live.

[Alex A]

I wish to replace a PIR lamp which has failed. When removing the old lamp, there were five wires 2 live, 2 neutral and an earth. However the two lives were connected outside the lamp terminals. Is this safe and, if so, how should the two neutrals be connected ?

Thanks.

You understanding is wrong and could lead to you doing something dangerous.

You might have two brown and two blue wires (or even old red and black wires) but you do NOT nave two live and two neutral. One pair will be live and neutral feeding the light fitting and the other pair will be the drop to the light switch so one will be permanent live and the other switched live.

If done properly the switched live will have been sleeved to indicate it's function. Often it is not.

So without some testing you could very well end up with a dangerous situation.

Post some pictures as it is now BEFORE you disconnect anything for more advice.
