Chinese fuses

THanks, Phil, I'll check it out. I actually cracked one of these 5A fuses apart today. Good news is it was at least sand-filled. Potential bad news, though, is the wire inside was much thicker than I'd expected to find; certainly a *lot* thicker than some 5A fuse wire off an old Woolworths bobbin I had lying around. I can micrometer them up for comparison purposes, but if they're made of dissimilar metals it's not really going to prove anything I guess. :(

There are some *known* fake Bussman fuses out there which are really dangerous. There was an item on them in the 'Fake Britain' BBC show recently.

Well how would you do it? I don't know the breaking capacity of mains plug fuses, but domestic CU fuses & MCBs are 1kA - 6kA, not exactly a trivial thing to set up on the workbench.

Have a good look at the 13A fuse in the first test.

Chinese fakers have no regard for brand names or anything else.
