I am having problems with an intermittant fault on one of my lighting circuits. One of the 6A mcb has garage lights connected to it (3rd mcb from the left in the picture). As I hope you can see, the mcb is on the non rcd side of the distribution box. The trouble is that often when the light is switched on or off, the rcd trips but not the mcb. Is this correct ?
To see if I can narrow the problem down, I am thinking of swapping the 2 6A mcb over. Can anyone can see an obvious reason for this fault.
Thanks.
