Guess I should of mentioned where I have been using it??
I'm currently an EE student and just finished Physics II, unfortunately that is the extent of my knowledge with electronics, but any how I've built a little lab in my bedroom and have been running some various experiments using my variac as a power supply. The variac has a 10 amp fuse, but after one of my homemade experiments blew the fuse, I've been using the 41 awg wire to prevent me from doing this again. I’m still using the 10 amp fuse in the variac, but also the homemade fuse in series. So I'm not really using the wire to protect my circuits, but instead my variac. My main concern with using the 41 and 44 awg wire, is the resistance of the wire effecting any thing? I’m not sure how the resistance of my fuse may compare to a real fuse? It just seems that 2-3 amps passing through such a thin wire is not a good thing?
I've ran several experiments on the home made fuse, and found that regardless of the voltage, the wire tends to blow around the same current levels.
And far as consistency between batches, I have a two pound spool of each, so I have miles and miles of wire to work with.
Thanks everyone for your input.
