It depends on where the sub panel is situated. If the panel is under the same roof as the main distribution panel then no ground rods are needed on the sub panel. If the sub panel is in a different building then a ground rod might be needed. There has been an electrical code rule change on this subject. Check with your local electrical inspector before installation so that it is done correctly.
Typically, two grounding rods are required for a 200 amp service. However, the exact number could vary depending on the local electrical code requirements in your area. It's best to consult with a licensed electrician for the most accurate information for your specific situation.

Should one or two electrical service ground rods be used on a service distribution?
In Canada the requirement for grounding purposes calls for two 5/8" x 10' ground rods placed 10' apart. If rocky ground is encountered, then a grounding plate can be installed. The grounding plate dimensions are 10" wide x 16" long x 1/4" thick. They are galvanized coated and must be buried 24 inched below grade.
What do grounding rods do?
Grounding rods are used to protect buildings and electrical systems from lightning strikes and electrical surges by providing a path for excess electrical current to safely dissipate into the ground. They help prevent damage to electrical equipment and reduce the risk of fires caused by electrical malfunctions.
Minimum length of a grounding electrode?
A standard ground rod is 5/8 x 10'. The amount of rods needed is governed by the electrical code. The largest type of grounding system is a Ufer ground. This is where the bare grounding conductor is embedded in the footings of the building and the weight of the building presses the ground wire to the earths surface. These types of grounds are used mostly in construction and are requested by electrical engineers.
Does the ground wire on a 200 amp panel need to be looped through both ground rods?
No, the ground wire on a 200 amp panel does not need to be looped through both ground rods. The ground wire typically needs to be connected to the grounding electrode system, which may include ground rods, but it does not need to loop through them. It is important to follow local electrical codes and guidelines when installing grounding systems.
How far apart do ground rods need to be?
Ground rods should be spaced at least 6 feet apart. If multiple ground rods are used, they should be installed at a distance from each other equal to at least twice the length of the longest ground rod. This spacing helps ensure effective grounding and minimizes ground resistance.
How many ground rods are required for a 200amp service in Indianapolis?
According to the NEC, if the ground rod supplements another grounding electrode such as a metal water pipe, you are required 1. If the ground rod or rods is your only grounding electrode, you are required at least 2, at least 6 feet apart. Check with your local jurisdiction for local requirements.
What size is the grounding electrode of a 400 amp service 500CM?
In Canada the grounding electrode requirement is for two steel 5/8" x 10' copper clad rods spaced 10 feet apart.
Should one or two electrical service ground rods be used on a service distribution?

How do lighting rods proctect structures?
By grounding electrical energy.
Do copper pipes need to be grounded?
No, the ground wire (green) can be strapped to any metal pipe going to ground. In the absence of a suitable pipe a metal stake at least 6 feet long can be driven into soil and the wire strapped to that.
How to Get the Most Out of Grounding Rods?
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. It’s 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.

What provides a pathway to drain excess charge into the earth?
Grounding rods or grounding wires provide a pathway to drain excess charge into the earth. These rods are typically made of copper or another conductive material and are installed deep into the ground to dissipate any excess electrical charge safely.
How many ground rods needed for a temporary service at construction site?
The NEC makes no provision for using 1 ground rod even on a temporary service. According to the NEC you must use 2 ground rods. However in my area we are allowed by the local inspector to use just 1. Call your local inspector and see what he requires as he has the last word on this.
How many ground rods are needed for a 100 amp service?
If you're asking this, you shouldn't be installing an electrical service. --- This type of question usually means you aren't ready to do this yourself. Study some electrical material and the National Electrical Code and work this answer out for yourself, or call a professional electrician. If I were to give you an answer, you might attempt to do something you shouldn't be doing, and that may cost someone a shock, a home fire, or their life.
How do you solve a floating earth problem?
Improve the grounding medium with more ground rods or plates and then ground the equipment to the improved grounds.
