Assuming this falls under the National Electrical Code (NEC) the size for the service ground is based on the conductor size of the Ungrounded (Hot) conductors. For 150A the size of XHHW Copper would be 1/0 for the Hot conductors and #6 AWG copper for the ground. Aluminum would be 3/0 for the Hot conductors and #4 AWG aluminum for the ground.

What size wire is needed for carrying 100 amps under ground?
To calculate the wire size, a system voltage is needed.
What size ground wire is needed for 20 amp?
A #14 wire will do fine for grounding a 20 amp device. That is the size of the ground wire in a 2 conductor # 12 wire building cable.
Ground wire size for 200?
A 200 amp service panel will require a # 4 bare copper ground wire.
Ground wire size for 125 amp service?

How do you know what wire is ground on 200 amp service?
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.
What size ground wire needed for a 200amp service panel in new jersey?
#6 bare copper wire.

What size ground wire for 100a service?
A 100 amp residential service requires a size #8 copper wire, it should be insulated in green.
Are there negative wire gauges?
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.
What size ground wire needed for 75 amps at 208 volts?
#8 copper
What size ground wire for 600 amp service?
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).

Can you have a smaller gauge ground?
Yes, NEC has an entire chart on grounding.
