A wire that is meant to take 1A will get 19 squared times hotter at 19A. That's very hot.

a wire meant to handle 1a would be between 29 and 30 gauge and you
will never see that used for 120 or 240v.
I pointed out earlier the smallest "fixture wire" allowed in the NEC
is 18 gauge.(1mm)

I've seen 2A wires. What is the difference between 2 squared heating and 19 squared heating?
