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.
#4 bare copper connected to two 8' copper ground rods 6" apart driven into the ground.
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.
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.

A 100 amp residential service requires a size #8 copper wire, it should be insulated in green.

A grounding rod is a ground electrode installed into the earth and connected to the grounded neutral of the electrical system which in turn grounds the entire facility. Itβs meant to keep the resistance low between the ground system and the earth. Grounding is an essential aspect of electrical systems that cannot be overlooked. A proper grounding rod protects against electrical shock and helps prevent equipment damage. How to Get the Most Out of Grounding Rods? Choose the Right Size The size of the grounding rod will determine its resistance to electrical flow, with larger rods offering better grounding than smaller ones. Proper Installation The rod should be installed vertically in the ground, with at least eight feet of the rod in contact with the soil. The top of the rod should be at ground level or below, and it should be driven into the ground using a driving tool. A bonding wire should be used to connect the grounding rod to the electrical panel or service entrance. Regular Inspection and Maintenance While most grounding rods are resistant to corrosion, regular inspection and maintenance are still necessary to ensure optimal performance.

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.
Having a smaller gauge ground wire may lead to increased electrical resistance and potential overheating. It is important to ensure that the gauge of the ground wire is appropriately sized to handle the electrical load and prevent safety hazards such as electrical fires. It is recommended to consult with a qualified electrician to determine the correct gauge for your specific electrical system.
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.

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
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.
Oh, dude, you're talking about a 150 amp service? That's like, pretty big, man. You'll need a 1/0 AWG copper wire for that bad boy. It's like the Goldilocks of ground wires - not too big, not too small, just right for keeping your electrical system safe and sound.
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.
In a 200 amp service panel, the ground wire is typically a bare copper wire or green insulated wire. It is connected to the ground bar within the panel. Make sure to consult the manufacturer's instructions or a licensed electrician for guidance specific to your installation.
