Browse Forums Lighting + Lighting Design 1 Oct 07, 2008 3:41 pm I went to replace a light today and noticed that the light (20 years old), had 4 terminals into which 9 wires went.
two wires, active and netural are the power source, whilst 2 sets of Act,Neutral,Earth are wired to carry to to another light (god knows why a splitter box wasn't used), and a final black line which I assume is the switch line. What I am not clear on is why the active from the forwarded power lines goes into the fourth terminal on the light fitting. What are there four terminals? Active. Neutral,Earth and what??

And don't do what someone I knew did many years ago - disconnect and separate ALL the wires at once, then put all the black wires back together (and he wondered why the rest of the lights in the house were only half as bright as normal ). The scary thing is he was an apprecntice electrician... Better still, get a licenced electrician to connect it up for you.
