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.

What size wire is needed for 1600 amp service?
A 1600 amp service typically requires 500 kcmil copper wire or 750 kcmil aluminum wire. It's important to consult with a qualified electrician to determine the exact size and type of wire needed for your specific installation to ensure safety and compliance with local electrical codes.
800 amp service using parallel sets of 500 cu what size grounding electrode conductor?
For an 800 amp service with parallel sets of 500 kcmil copper conductors, the grounding electrode conductor size should be based on the largest conductor in the parallel set. The grounding electrode conductor size should be sized based on Table 250.66 in the NEC, which recommends a minimum size of 3/0 AWG copper for 1/0 AWG or larger service-entrance conductors.
What size ground do you need for 4000 amp service?
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.
Ground wire size for 125 amp service?
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.

What wire size is needed for 1800 amp service?
There is no one wire that is rated for 1800 amps. The service will have to be a quad parallel of the conductors. A 600 MCM conductor with an insulation factor of 90 degrees C is rated at 475 amps. This conductor paralleled into four equal lengths will give an ampacity of 1900 amps for each leg of the service.
