Hi guys, quick question. This evening I've installed a new light fitting in my front room, it's got 3 gu10 spots on it. When I took the original pendant off there were 3 lengths of T+E coming down. So to get them all in I changed the terminal block to a 15amp one. I matched up the wires, put the fitting up, switched the breaker on and it worked. Then I flicked the switch and the breaker tripped!!!
I can turn the fitting on and off from the breaker but if I use the switch it trips instantly, if I push the switch to what would be the on position and turn the breaker back on it works. If I leave it in the off position it trips!
