I think this may just be iron wire used as the current sense
resistor, with the lack of body providing better air cooling
-throw than a solid body type would. Given that even this
one gets toasty, a solid body one would probably fry or
*****.
^^^^^ that was a perfectly good English word used
appropriately - c,r,a,c,k. Mods, can you train the censor
to accept real words from the dictionary?
I see iron wire used as the sensing resistor in cheap DMMs
I have, on the 10A jack.
