[QUOTE="user 37656, post: 551563, member: 37656"] I've replaced a 28w CFL kitchen light with a fitting that holds 4 x GU10 (LEDs). When I turn the light off, the MCB trips. If the light switch is on when I reset the MCB, it remains on, but if I turn it off, the MCB trips. Sometimes the RCD also trips. To rule out a faulty bulb I removed all bulbs, then I removed the light fitting itself - so no I just have wires - the issue remains the same. I also didn't take a picture of the previous light wired up - though I do remember that the Neutral and Live wires were not twisted together as the fitting is different. I've attached pictures of the original circular fitting, the new fitting, and the wires as they are now. Any suggestions of how to move forwards would be welcome - I've replaced plenty of lights before but never had this happen. Thanks for your help. :) [URL='https://photos.app.goo.gl/EBwNk7NpYo7hGCNb8']Pictures[/URL] [/QUOTE]
