Absolute nonsense. No lamp filament has ever shorted out a circuit. If
the filament is dodgy it blows and it burns out way below any fuse level
You are talking absolute crap. I suspect you are in second term of an
electrical engineering course and think you know everything already.

LOL!

See my earlier posts explaining how this common occurrence regularly
happens, and regarding my credentials.

I suspect, however, that your "knowledge" in electrical matters is somewhat
more limited!
