You need to say whether it's a 150 amp service or a 1200 amp service it has to be one or the other.

A 1/0 copper conductor with an insulation factor of 90 degrees C is rated at 155 amps. There is no ground wire stated for a 150 amp service so the next size up is a 200 amp service. The ground wire for this size is #6 bare AWG.
Without knowing what types of loads that are coming off of the distribution a reduced neutral can not be recommended. The neutral will be the same size as the service conductor which is 1/0.
From the question it is hard to establish whether the service size is 350 amps or the service conductors are 350 MCM in parallel. If the service is 350 amps, the grounding conductor is #3 bare copper wire. Parallel 350 MCM conductors will allow for a 600 amp service. The grounding conductor for a 600 amp service is a #1 bare copper wire.
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.
The size of the ground wire for a circuit is typically based on the size of the circuit breaker protecting that circuit. For a 200 amp circuit breaker, the recommended ground wire size is 4/0 AWG (American Wire Gauge) copper wire. This wire size helps ensure that the ground wire can safely carry any fault currents that may occur in the electrical system.
A Harley-Davidson 1200 model typically has an engine size of 1202 cc.
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.
A 100 amp residential service requires a size #8 copper wire, it should be insulated in green.
For a 1200 amp service, the National Electrical Code (NEC) typically requires a grounding electrode system that includes a ground rod of at least 5/8-inch in diameter and a minimum of 8 feet in length. If using a copper rod, it should be at least 5/8-inch in diameter. Additionally, multiple ground rods may be required if the resistance to ground exceeds certain limits, so it's important to consult local codes and a qualified electrician for specific requirements.

For a 100 amp service in copper, a wire size of 3/0 AWG should be used.
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.
For a 50 amp RV service, a wire size of 6 AWG should be used to safely handle the electrical load.
Depends on the breed and size from $1200 to $20000
For a 30 amp RV service, a wire size of at least 10 gauge should be used to safely handle the electrical load.
