That cord is designed to safely handle 30 amps. A stove may draw 40-ish amps, and might be fused for 40 or 50 amps. SO, the fuse does not protect the cord from being overloaded. In the scenario you describe, we do not jump right to "fire"...but the insulation might get too warm, could even melt, and eventually bad things could happen. The different PLUGS are "different" for this exact reason...so you can't plug into the wrong place!
