hello, i wonder if anyone can help with a very strange situation. I have 2 double strips not working. swopped one for a working one and it doesn't work.
The problem is there is no live into the strip but there are 2 spare wires together in a grey cable red and black that show 240V on the outside of the strip in a block connector.
there are 3 red wires and 3 black wires with an earth connected to the strips electrics.
has anyone got an idea. They were working last week????????
I took the strip down and wired it to the mains and it works????
