Have looked in the FAQ but no answer to this there...
My electrical consumer unit has MCBs. In the house, each light switch controls just one light EXCEPT in the lounge where the light switch controls 10 lights all at once (two pendants each containing 5 bulbs). Whenever one of the lounge lights blows, the MCB trips, but this never happens when any of the other lights blow.
Unfortunately the consumer unit is in the garage, only accessible from outdoors, so when this happens in the middle of the night it's inconvenient to say the least. Is there any particular reason why the lights in the pendants cause the MCB to trip when other lights don't? Is there anything I can do about it?
(The lounge light switch is a dimmer, with press-on-off action.)
