I would be grateful for your advice. I want to connect an external ceiling light to my porch canopy. The electrical wiring coming from the house through the canopy consists of live, neutral and earth wires, together with a second and thicker earth wire. The connector box on the ceiling light has the following: labeled 'Mains Supply In': consisting of Earth, Neutral and Live connector boxes; and 'Switched Load Out': consisting of two live boxes labeled 'L' and 'L1'. The 'Mains Supply In' 'Live' connector box is already connected to the Switched Load Out 'L' connector box by a Factory fitted bridge wire. I should be grateful if you could advise me to which connection points in the ceiling light housing I should connect the live wire and the two 'earth' wires from my porch ceiling.
