So just now I was adding an extra light over my day bed it's a vintage 60 watt bulb looks like an old radio valve it even has the little glass pip on top. Anyhow as I was wiring it up two whiskas of wire touched there was barely any sound but it popped the 5 amp fuse in the plug adaptor and tripped 16 amp MCB how is this even possible even under partial short circuit conditions surely a 5 amp fuse should clear before a 16 amp MCB?
Chris. Yes, My compact florescent certainly went dim prior to failing, But LED's - well despite buying what I believed were a decent brand "Crompton" I have been through about two dozen GU10s in our study/home office. It certainly is overheating. Imagine a glass plate about 4-inches away from the ceiling with 4 holes drilled through the glass. In each hole is a spider supporting a GU10 holder. Plenty of air circulation. Also three wall lights. However not just the GU10s but also 4 foot and 5 foot flourescent replacement LED tubes. Have had 2 of those fail, one in the kitchen and one in the bathroom, so that is three different circuits/MCBs.
Our supply is underground TN-S So whilst not as likely as TT for weather related surges am wondering whether I should have a SPG device fitted?
