Lamps blowing simultaneously.

[babyshanks]

Hi guys. So, I was sitting at home revising for my 2391 and suddenly a small bang and I was plunged into darkness. Checked the board and sure enough the breaker for the lighting had tripped. Flicked it back on, and now two lights next to the board have both blown, whilst the remainder of the lights are working fine.

Any ideas as to why this might have happened? Cheap bulbs? Some kind of surge? It looks as though the two that have blown are the first two lamps on the circuit.

Any help is hugely appreciated!

If your competent to do so (if your doing your 2391 you should be) check the connections for that circuit at the board, maybe just a loose terminal.

Lamps, well filament types have an inbuilt fuse and is meant to rupture when the lamp goes. With cheap lamps, the MCB usually reacts first due to the fuse within the lamp being lower quality
