Answer / rajeshsan
There are many reasons for using gravel stones of 60mm size below transformer. Few are:-
1. During oil spillage from transformer or during sprinkler system act the water draining from soak pit it will be easier.
2. To avoid the grown of grass and entry of animals etc.,
3. To reduce the step potential
You can please refer the NFPA 850 for details.

In three pin plug 6 amp. 220V ac rating. Why earth pin diameter is higher than other two pin? What its purpose ?
How one may guess the direction from which the distribution line is incoming if there is no pole plate on poles?
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?
