I have been looking for smaller gauges of wire for a wire-wound tank heater.
36 Gauge 7/44 wire is an example.
7/44 means it is multi-stranded, that the 7 strands of 44 gauge together make 36 gauge.
ALL I NEED - wire that has a resistance of about .2 ohms per foot.
I would rather use copper wire than nichrome or anything like that.
I have already made a few good tank heaters using anywhere from 22 gauge to
30 gauge, using PC power supplies to provide the juice.
It is just rather surprising to do a websearch and find, almost no smaller diameter hook-up wire.
The gauge I want to use is a little like a single strand of Cat 6. I tried using some Cat 6, using just one strand and about 15 feet of wire on maybe 5 volts.
The Cat 6 single strand is just an example of a gauge similar to what I need.
Overall what I will use is about 150 feet of wire.
Since it's for a 300 watt heater, it wouldn't hurt me to use more wire.
If I could find a 500 foot spool that was close to the right number, I would buy that, epoxy it up, add some external connectors, and that could be my heater. (Not the best shape, but it is close to the essence of a wire-wound resistance. They don't really care whether they are wound on ceramic, plastic, or metal.)
Amazon hath failed me.
