Wow. Same screw-in fuse here in USA.
I always wondered why it was the same. Speculated that it was to save tooling costs. Brilliant. Mike - AA8K Poul-Henning Kamp wrote:
I don't know if this was the same in other countries, but the first set of screw-in fuses approved for house installation in Denmark had the same E27 screw-socket as lightbulbs, for exactly that reason and some electricity companies delivered a 100W lightbulb attached to the fusebox with a string. The official pamphlet that came with your new electrical installation, adviced that you should always have a working 100W bulb next to your fusebox, so that when the fuse blew, you could screw in the lightbulb to find where the short were. It gave a very clear procedure, but did not actually explain how this worked, leading a lot of people to believe that the 100W bulb attached with a string was "special". Poul-Henning
