It allows for a separate equipment grounding conductor
Why does in an electrical plug the earth pin is longer than other two...what is its main function?
The earth pin is called the equipment grounding conductor. The National Electric Code requires this conductor to be the first to make contact with the receptacle and the last to break contact with the receptacle, the way manufacturers comply with this requirement was to make the pin longer.
Can a duplex receptacle be installed in a non plenum ceiling cavity?
Yes, a duplex receptacle can be installed in a non-plenum ceiling cavity. However, it is important to ensure that the installation meets local electrical codes and regulations. Additionally, proper wiring techniques and safety precautions should be followed to prevent any hazards.

May a GFCI receptacle be installed as a receptacle in an old installation where the 2-wire circuit has no equipment grounding conductor?
Actually, yes. The GFCI does not need any ground; it measures "leakage", i.e., an imbalance, regardless of whether there is "ground". The National Electrical Code permits installing a GFCI to replace a completely ungrounded receptacle. Others have said: No. The GFCI is designed to measure an unintended path to ground. Without a good ground reference this is not possible.

What is the difference between protective and functional earth?
protective earth (PE) is a conductor, other than a main earthing conductor, connecting any portion of the earthing system to the portion of the electrical installation. functional earth (FE) is an earthing arrangement provided to ensure correct operation of electrical equipment or to permit reliable and proper functioning of an installation

What does the National Electrical Code NEC say about running separate ground wires?
From the 2011 NEC, Section 250.130 states, in part, "For replacement of non-grounding-type receptacles with grounding-type receptacles...connections shall be permitted as indicated in 250.130(C)." Section 250.130 (C) states in its entirety, "(C) Nongrounding Receptacle Replacement or Branch Circuit Extensions. The equipment grounding conductor of a grounding-type receptacle or a branch-circuit extension shall be permitted to be connected to any of the following: (1) Any accessible point on the grounding electrode system as described in 250.50 (2) Any accessible point on the grounding electrode conductor (3) The equipment grounding terminal bar within the enclosure where the branch circuit for the receptacle or branch circuit originates (4) For grounded systems, the grounded service conductor within the service equipment enclosure" (5) For ungrounded systems, the grounding terminal bar within the service equipment enclosure" Now for some of my thoughts. It sounds like what you got was adequate. It was correct except for he should have used green or bare conductor, not white, unless he used green tape near the end of the conductor to designate it as green. This tape would be inside the box but I would have marked it outside the box also if it is visible. I would have run this conductor as close as possible and preferably attached to the existing circuit conductors. Looping the conductor as you have stated is not the best installation, in my view, but if you have at least 6 inches from the entry of the conductor to the grounding terminal and another 6 inches before it leaves the box, this is ok. The code does not require this 6 inches if the conductor isn't spliced but in your application it should be since, in my view, it should have been spliced. Solid or stranded is of no significance. While I have quoted the 2011 NEC in my answer, I do not expect this has changed any in recent years. The use of the word "bonding" by your electrician was technically incorrect but "bonding" and "grounding" are sometimes used synonymously. They are different but often look alike to the untrained eye. Even electricians often misuse these terms and fail to understand the difference. It takes someone like myself who is a little anal retentive to use the terms properly. I hope you will acknowledge my answer as I am particularly interested to know if you got it.
Is a receptacle safe to use after an electrical arc?
Most of the times yes. If it is an appliance that gets pulled out of a receptacle under load and there is a small arc produced this will not damage the receptacle. It will pit the blades inside the receptacle but not enough to render the receptacle unserviceable It is not recommended to use this method to disconnect electrical equipment, use a switch in the circuit as they are designed to open a circuit under load.

Can you power one conductor of your service panel with one generator and the other conductor with another generator?
Yes, this can be done but this sounds like a hypothetical question. The one draw back of this type of installation is that no 240 volt equipment could be connected to the panel. If the two generators were synchronized to run 180 electrical degrees in relationship to each other and maintain that separation then 240 volt equipment could be connected.
