A 200 amp service using a uffer ground will need a #3 bare copper wire. The bare copper wire is to be not less than 20 feet in length. It also has to be within 2" of the concrete foundation footing that is in direct contact with the earth. The depth can not be less than 2 feet below finished grade.
NEC code requires #6 bare copper.
Yes, there are ground wire gauges. The approiate size ground wire must be matched to the size service you are installing. For instance a 200 amp serivce must be grounded with a # 4 bare copper ground wire.
#4 bare copper connected to two 8' copper ground rods 6" apart driven into the ground.
A 200 amp service panel with a 60 amp sub-panel.
AWG # 3/0 copper.
A 200 amp service panel will require a # 4 bare copper ground wire.
200 amp service in chicago uses 3 aught.
NEC code requires #6 bare copper.
On a 200 amp or any size service the ground wire is easily identified. Look in the distribution panel for the neutral bus bar. This is where the service neutral (white wire) is connected to the distribution panel. There you will see a bare copper wire connected to the same neutral bar. This is the ground wire that is connected to the ground rods out side of the house.

The wire that is used for connecting the ground rod or plate to the electrical distribution is governed by the size of the electriclal distribution. In Canada a #6 bare copper is the minimum size for a 200 amp service.
In Canada it is a #6 bare copper conductor that connects the grounding rod or plate to the neutral point in the distribution panel.
Answer for USA, Canada and countries running a 60 Hertz supply service.CEC states that a #3 bare copper conductor is a common grounding conductor size for a 200 amp service panel and it is the minium size for service raceway and service equipment of 400 amps.
This can't be answered without knowing the voltage, and ground is not the same as neutral, in AC circuits, which I'm assuming this is.
The wire size used in a service entrance distribution panel is governed by the size of the services over current device. The larger the service, the larger the fault current could be, the larger the ground wire to carry the fault current to ground. If the largest service conductor carries 100 amps use a #8, 200 amps - #6, 400 amps - #3, 600 amps - #1, 800 amps - 1/0 and over 800 amps - 2/0 for the ground wire. <<>> Golden Valley Electric Assoc. in Alaska requires #4AWG copper wire for a ground from the breaker box to earth ground rod. The same goes from the service entrance panel on the pole.
You do not use a ground wire in the connection from the meter base to the distribution panel. A bonding wire may be required if the service is using PVC conduit.
