I have a consumer unit in my garage which has a circuit for sockets and a lighting circuit. On the lighting circuit is a flo tube and 3 outdoor lights and a security flood light. The lights are on a 3 gang switch the flo tube being two way with another switch else where. When the outdoor lights are turned on all works fine but sometimes when they are turned off the main mcb will trip instead off the mcb for the specific circuit. It happens mainly with the outdoor lights but sometimes happens with the flo tube as well.
Any suggestions appreciated
