I have an existing lighting radial that ends with 3 x LED downlights which are all 230VAC integral units (cannot remove bulbs).
I'm extending this by another 3 lights so I'm picking up the supply from the 3rd light and daisy chaining them up using a wago light junction box.
So how do I test this circuit?
I don't want to megger them with the LEDs in and surely the resistance readings will be influenced by the transformers inside the LED units?
If I take all the lights out and then link evrything together to test, this is a poor reflection of what will be the final installation and the only test I would be happy with would be the insulation resistance, in which case I could just test the full length of this now before I cut the newly run wire where the lights will drop from.
I could just megger them at 250V but still not sure about the R1+R2.
