The size(cross sectional area) of the conductor for a
particular load not only depends upon the current drawn by
the load(nature of the load), it also depends upon nature
(resistivity) of the conductor material(i,e; whether the
conductor material is made of copper, silver or any other
material). It also depends upon the external physical and
environmental conditions.

For refrigerators the motor current is raised beyond its rating on both conditions when the voltage of the system is more(say 270v) than the rated voltage(220v) as well as when the voltage of system is less(say 160v) than normal voltageof 220v, why explain?
