I'd expect Voltage Drop on the wire to be the source of any problem.

Luck of the draw whether the heat happens high enough on the wire itself first -- or localizes at the appliance. Well, not luck, exactly, but dependant upon appliance design. The designers could not be blamed in this instance, they did not design the appliance to be used in that manner, of course. Presuming a "proper" AC hookup, the appliance itself was likely a fine design.

That said, I've seen very few internal consumer equipment transformers that could actually start a fire. Most are enclosed in steel or at least well wrapped in fish paper and copper shielding and placed well away from other components in the chassis.

But you know the drill.

Feces occurs.

Right?
