Hi, Paul.
The MCBs were new about 3 months ago-fitted with an ELCB to replace
*stone-age* fuses-one serious electric shock in a lifetime is enough for me.
I can live with it.
But here's a wierder one still. Driving past the outside security light, it
detected me and came on. Then it burned hyper-bright before going pop. The
next evening, the thing came on at normal brightness, before going pop and
blowing the outside circuit's 5 amp fuse. Replaced halogen bulb and fuse, no
problem *but* ...
(a) how did the dead bulb briefly fix itself.
(b) why didi it blow the fuse w/o tripping the MCB/ELCB
Yours,
Mystified of York.
