Agree to disagree. Submitter was smart enough to measure resistance in their chosen wire, and understand the rough ideas of current limits: that's a hacker in my book.
"Here are the things I know" + "Here are the things I know I don't know" + "Can you help me?"
I'm sure there's a ton they don't know they don't know (stranded vs solid core AWG equivalency), but this is a pretty simple use case -- running power a relatively short distance in a temporary install.
The worst that can happen is they or someone on the street short across their heart and dies. Which would not only require shocking yourself, but doing so in a pretty specific orientation.
But they're already in a warzone! That risk is lower than their base level of environmental lethality.
