If something at the end of the lamp cord drew 19 amps, the cord would get very hot, and melt its insulation, and then the cords wires would likely touch, and draw a lot of current for a very short period of time and the breaker will open. I think what you are getting at of course is that nearby flammable materiel's could be ignited.
Seems to be everybody is forgetting the breaker supplies short circuit protection first and foremost. The device plugged in is supposed to provide it's own thermal protection . Is an explanation needed for short circuit protection and thermal protection which are different.
