That is not how it works.

When you short something to ground, it's everything in between that needs to dissipate the heat. Think about what "sending it to ground" means---it means you connect the hot to the ground. But with what do you connect the two? A wire? Sure, but you better hope that wire can dissipate all that power, because that's what it'll try to do.

You can't just "dump power on the ground." That's not how it works.

    So, I'm not good at these things, what you're saying is that if I take a 240V cable in the street and just shove it into the ground, the cable will end up uh... melting? Trying to saturate itself until it matches the resistance of the ground or something?

    If it's a low resistance path to ground, it'll get very very toasty! If it's a lousy ground though, then it won't...but it also won't consume any power, so it's not an effective way of scrubbing off electricity.

    A good ground (low resistance) is found in your household wiring (the ground and/or the neutral). Of you short to that...well...you can guess what will happen! (Let's hope you have proper circuit breakers.)
