Fuse blowing

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?

    Although, to be fair the DNO pretty universally trumpet a value of 0.35 Ohms


    I was told this categorically on a recent application for a 630A service  - and no amount of me pointing out that wasn't credible based on the ASC and their obligations under ESQCR in terms of voltage was going to make them change their mind, no siree, Bob


    Some DNO's are better than others though - or at least with some it's easier to fight your way through to the technical guys to get some sense
