What is the difference between short-circuit and overloading?

The differences between short-circuiting and overloading are: 

Short-circuiting Overloading
Short-circuiting happens when a live wire comes in contact with a neutral wire. Overloading happens when the amount of current drawn by a source exceeds the amount of current that a source can supply.
At the point of short-circuit, the potential difference falls to zero. Potential difference assumes non-zero but a very low value in overloading.
The current flow is high at the time of short-circuiting. During overloading, the flow of current is lower than the flow at the time of shortcircuiting.

        If Bohr’s quantization postulate (angular momentum \( = \frac{nh}{2\pi} \)) is a basic law of nature, it should be equally valid for the case of planetary motion also. Why, then, do we never speak of quantization of orbits of planets around the Sun? Explain.
