What is a conductor used to connect equipment or the grounded circuit of a wiring system to a grounding electrode or electrodes?
Jessram
The conductor used to connect equipment or circuit to an earth electrode is earth bond or in some cases a supplementary bond. This will be generally carried out using a copper tape or an earth cable.

Iec 60502 2xfgy 61kv xlpe can you use the armour as grounding conductor?
NO some armored cable has a ground some sealtite has copper in the helix wit the drain shield some liquite has no conduction at all all armor is a helix which is a coil and acts as insulation at hi frequency xlpe cross linked polyethylene is an insulator service cable is never used for grounding grounding electrode conductor grounding equipment conductor grounding conductor are all separate from service cables if a tall trucks hits an overhead cable you dont want to lose the ground in short NO
What is the difference between pipe earthing and plate earthing?
Assuming your reference to "earthing" is grounding (Grounding Electrode Conductor), a pipe is, as it sounds, a pipe (i.e. water pipe). A plate would be, as it sounds, a square (or rectangular) copper plate which would be buried in the ground.
What is the definition of the connection between the grounded circuit and the equipment grounding conductor at the service?
2008 NEC - Article 100 Definitions - Bonding Jumper, Main Main Bonding Jumper is the answer.
What is the process of charging a conductor by bringing it near another charged object and then grounding the conductor called?
Induction
What is an earth pit?
An 'earth pit', is a pit in which connection is made between the earthing (grounding) electrodes that have been hammered into (or laid into) the soil, and the earthing conductor that connects the electrical installation to those earthing electrodes.

Grounding Electrodes and Grounding Electrode Systems All grounding electrodes present at a building or structure must be bonded together to form a grounding electrode system, as required by NEC® Section 250.50. Doing so eliminates voltage gradients, and also improves reliability and grounding performance over time by creating redundancy. If one electrode is damaged, destroyed by corrosion, or removed, other electrodes are available to maintain the all-important connection from the service equipment to ground. Section 250.53(B) states that two or more grounding electrodes effectively bonded together are considered a single grounding electrode system. Permitted Electrodes The NEC recognizes the following seven types of grounding electrodes [250.52(A)]: Metal underground water pipe Metal frame of a building or structure Concrete-encased electrodes Ground ring Rod and pipe electrodes Plate electrodes Other local metal underground systems or structures (piping, tanks, well casings, etc.)
If you have a 400 Amp service using 500 MCM What size grounding electrode conductor is required?
#2
Does the Nec allow grounding electrode conductor to be run in conduit that has other conductors in the conduit and what code section?
No, the bare copper grounding conductor can not be in a conduit with other conductors. It can be in conduit by itself to provide mechanical protection for the wire.

What should the clearance be from service entrance panel to grounding material?
grounding material is not a good word but as short as possible is a good answer the entrance panel must be connected to the best possible ground this is called the grounding electrode the grounding electrode conductor connects to the ground bar in the entrance panel if the panel has a a neutral the neutral bar can be bonded to the ground bar Grounding electrodes form best to worse well casing water pipe (NOT plastic) buried plates or wire grid or bonded reinforcing steel driven rod if you are talking about distances to the panel it should be centered about shoulder height doors need to have about 2' of clearance in all directions weather open or shut
