I have just fitted a new light and it keeps blowing my MCB
There were only three wires coming from the ceiling and therefore I am certain it is connected properly but this new light has a transformer and 21 x 10W bulbs.
If I turn the light on and then turn on the MCB it works fine.
If i switch on the light at the switch it blows the MCB
The rated voltage of the new light is 240V ~ 50Hz
bulb type 12V G4
rated watt 21 x 10W
