A 100 amp residential service requires a size #8 copper wire, it should be insulated in green.
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.
Use AWG #1 copper service entrance wire and #4 copper ground wire.

200 amp service in chicago uses 3 aught.
The 200 amp ground wire size chart provides guidance on the appropriate size of ground wire to use in electrical installations that require a 200 amp service. This helps ensure safety and compliance with electrical codes by ensuring proper grounding for the system.
For a 400 Amp service with 500 MCM conductors, the minimum size grounding electrode conductor required would be 3/0 AWG copper or 250 kcmil aluminum based on the NEC Table 250.66.
NEC code requires #6 bare copper.
For a 125 amp service, a ground wire size of 8 AWG copper or 6 AWG aluminum is typically sufficient. However, it's important to consult with local electrical codes and regulations to ensure compliance with specific requirements in your area.
500 mcm
For a 4000 amp service, a grounding system with at least 2/0 AWG copper or 4/0 AWG aluminum wire is typically required. The exact size of the grounding system will depend on factors such as the type of soil, moisture levels, and fault current calculations. It is recommended to consult with a licensed electrician or engineer to determine the specific size needed for your installation.
The recommended conduit size for a 200 amp service is typically 2 inches in diameter.

Ground is sized based on the size of the feeder wire and not the amps of the service! However, for a 600 amp service 1500MCM copper wire is one option (NEC 310.16) ;therefor, ground wire is 3/O copper (NEC 250.66) or another option is a two sets of 350 MCM copper wire then a #2 copper (since the biggest feeder wire is 350MCM).
The recommended wire size for a 60 amp service is typically 6-gauge copper wire.
