You will need two 8 foot ground rods. One placed under the meter base and another one placed 6 feet to the side next to the foundation. If this is a home I highly recommend you install a 200 amp service instead of a 100 amp service. Not much more expensive and you will have plenty of room for growth.

What size cold water ground for a 200 amp residential service?
#4 bare copper connected to two 8' copper ground rods 6" apart driven into the ground.
How to ground and bond a panel?
It must be grounded outside with two 8' copper ground rids driven fully into the ground. One under the meter and one 6' to either side connected together with the proper size copper ground wire. The above answer leaves out the requirement for a grounding connection to a metal water pipe. The NEC actually makes the ground rods supplemental to the water pipe. We don't usually consider the water pipe as the primary grounding electrode but that is how it is treated in the code. Depending on the size of your service, the grounding electrode conductor to the water pipe may actually be a different size than what connects to the ground rods, which are allowed to be connected with 6 AWG copper regardless of the size of service.
What size ground wire to water meter for 400 amp service?
You need 2 ground rods of 8' in length. One under the meter base and another one 6' to either side of the meter base. Drive them into the ground with just enough sticking up to connect the ground wire.
What is the minimum size alluminum ground for a 200A service?
250 mcm
What size ground wire for 100a service?
A 100 amp residential service requires a size #8 copper wire, it should be insulated in green.
What size cold water ground for a 200 amp residential service?
#4 bare copper connected to two 8' copper ground rods 6" apart driven into the ground.
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 is rod earthing?
It is the installation of ground rods at a service entrance distribution to bring the relative resistance to ground to be within 5 ohms of the utility's distribution network. This grounding system is then connected to the service distribution with a calculated size wire and connected to the distribution at a point within the distribution panel, where the service neutral wire joins the neutral bus bar.
What size ground wire to water meter for 400 amp service?
You need 2 ground rods of 8' in length. One under the meter base and another one 6' to either side of the meter base. Drive them into the ground with just enough sticking up to connect the ground wire.
What meter is best to check the earthing system?
1.take 2 wire and connect with a bulb holder along with a bulb 2. then put the two open ends to the plug, one in the live line and another end to the neutral end 3. switch on the supply & check brightness 4.switch off supply & plugged out wire from neutral end & put it into earthing point 5. switch on the power, check brightness ,if it is same as before then EARTHING is very good if not then there is a problem with the earthing point
What size ground wire is needed for a 150 amp service?
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 is the minimum size of service entrance conductor?
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.
What size ground do you need for 4000 amp service?
500 mcm
Ground wire size for 125 amp service?
six awg
What is the minimum size alluminum ground for a 200A service?
250 mcm
Is the size of the ground wire important?
Yes, it has to be sized to the main circuit feeders to be able to carry the fault current of the main feeders if a fault occurs. Sizing of ground wires for service supplies can be found in the electrical code book. In cable wire sets the ground wire is determined by the manufacturer of the cable.
