Lighting Problem.

Zoomup
In my living room I have three lighting points. One is a centre ceiling point that had  a 100 Watt G.L.S. incandescent lamp.


Then there is a wall light where the bulb has blown but I have not renewed it as it is difficult to access.


And lastly there is another wall light where the 40 Watt G.L.S. incandescent lamp was working.


Last night the centre light and one wall light were working fine through the non-L.E.D.compatible dimmer switch.


This morning it was a bit gloomy so I turned on the dimmer switch and the B6 M.C.B. tripped off in the consumer unit. 


An ideal opportunity to change the dimmer switch for a new L.E.D. compatible type I thought. So I changed the dimmer, reset the B6 M.C.B. to on and discovered that I had no lights at all.


Why?

    Back to Zoomy's problem. The MCB tripped, but did both filaments blow at the same time? If so, why?



    That stumped me as well Chris. It appears that both filaments blew at the same time.




    What I meant was did both filaments blow at the same time as the MCB tripped? Could there have been an overvoltage?
