Christian:To my knowledge a 10 A fuse does not blow immediately if you draw more than 10 A from it. In fact, IIRC, you can draw 12 A for half an hour, 15 A for couple of minutes and 20 A for a couple of seconds, before the fuse blows.
Correct, a few years ago at work we had a problem at work where we were blowing one of the main fuses. It was rated at 630 Amps, the distribution board had a built in Amp meter. We found it would have to run at around 1200 amps for around 20-30 mins before it would blow. It could run at around 800 for around 90 mins.
