I think what is alarming some is the acknowledgement by some who have survived a major event. When you have personally experienced an event and live, you have a different attitude to going for a fuse replacement without testing first. OK 80A or 100A fuses wont bring the house down, but what size fuse would you consider too big to risk ? - You may think its OK the fuse will hold itself together thus containing the explosion but sometimes it does not end there. The risk of a blinding flash and hot metal splatter, you will live from but you will end up with an unwanted tan and a visit to A&E to get the metal out of your eyes.And yet everyone I know has a story of a big bang that happened to them, I've never met an electrician yet that hasn't had quite a big shock at some stage despite being a professional, I'll bet you have, sometimes things go wrong and 99.9% of the time you live to tell the tale, ---- happens.
As for the tester, wouldn't it light up anyway with a path through the meter as it was still wired in at that stage. The fuse I replaced (twice) was out of one of those isolatotor units where you get a pack of three 60/80/100 and when it didn't work my initial reaction was it must have been a cheap chineese fake fuse that just stopped working, no other explanation really.
Can you explain how a perfectly working cutout suddenly developed an absolute dead short to ground overnight without anyone being anywhere near it. I had a prod around inside it to try and see and the top of the carrier still looked like it was sat on an insulator to me.
Personally i have taken out one head fuse and one substation fuse in a long career, neither were due to energising , mistakes made under pressure.
I think you will find - energising a supply without testing to be offensive to some and do hope you continue to be lucky.
