WHAT IS THE REASON FOR THE GROUND PIN IS BIGGER IN SIZE
COMPARING TO OTHER PINS?
Answer Posted / sandeep
The ground pin is longer so when you insert the plug, the
earth connection is made to the equipment first.
When you remove the plug, the earth connection is removed
last. This is for the user safety.
It is bigger so you can not insert the plug in any other
way. The smaller pins on the plug can go into the larger
hole, but the larger pin will never go into a smaller hole.
So any live wire cannot be connected to the body of the
equipment.
