Re: Socket dilemma
The ground wire is for personal safety. For any appliance with a metal chasis, the ground wire is connected to it. It is there in the event that a live wire comes in contact with the metal chasis and energizes it. Should that happen, the current will flow back to the panel and trip the breaker. If this path was not there, any person who came along and touched the metal chasis would be electrocuted.
