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.


What is the NEC code requirement for installing 2 ground rods?

The NEC code requires that two ground rods be installed at least 6 feet apart and connected with a grounding conductor.


How many omhs of resistance does a ground rods have?

The resistance of ground rods typically ranges from 1 to 25 ohms, depending on factors such as soil conductivity, rod material, length, and installation method. Ideally, grounding systems should aim for a resistance of 5 ohms or less for effective grounding. However, in some cases, achieving lower resistance may require multiple ground rods or additional grounding techniques. Always consult local codes and standards for specific requirements.

Improve the grounding medium with more ground rods or plates and then ground the equipment to the improved grounds.


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 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.

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.
