I have several light fittings which take 5 of 50W GU10 halogen bulbs.
I have run the fittings with dimmer switches with more than adequate ratings (eg 750W).
Operation and dimming work absolutely fine until a halogen bulb fuses, when it burns out the dimmer switch.
The first time this happened I put it down to bad luck, but I've now burnt out three! On only one of these occasions it tripped the fuse at the consumer unit.
I can only assume that the fusing of the bulb has caused a momentary short circuit, but don't know how to avoid this.
Any ideas?
