Guide for Generator Grounding

To connect an electrical circuit for a referenced ground, you need to ground your generator.

But before we delve into the process of grounding the generator, let’s understand what we mean by a referenced ground. A referenced ground refers to a metal rod and a copper wire. The electrical connections in a generator can mean different components such as the engine, gas tank, or generator’s frame.

Benefits of grounding your generator

In case you have a generator, you will want to stay safe. You don’t want a situation where someone gets injured during your camping because the generator wasn’t well grounded. Also referred to as earthing, grounding is a process where an electrical device is connected to the ground to keep it safe. By grounding your generator, you ensure that there are no chances of electrocution and electrical fault.

On the other hand, if the generator isn’t well-grounded, an electric efflux can travel inside the connection and cause damage to the generator.

Key tip on grounding a generator

Before you start to ground your generator for camping, here are a few tips you need to follow:

Ensure its dry

Trying to ground a wet generator can be a risky affair. Ensure that your hands are also very dry. You should then do it on dry ground that is sheltered from moisture.

Stay safe

You will want to give special attention to your safety before you can ground a generator. We recommend that you use a copper wire and an 8-foot metal rod to ground your generator. Ensure that the direction of the wires will be away from the campsite.

Ensure low resistance

When the separate grounding is processed, you should ensure that there is low resistance in the grounding and bonding. You can use the resistance of 0.2 ohms or less in the ground wire as well as the metal stake. On top of that, you should ensure that the bonding connection can conduct electricity when there is a short or a lightning strike.


How to ground a generator

Before you start the process, you will want to gather the necessary supplies. These include:

  • Copper rod. This is the rod that is stuck into the earth for grounding the  generator. You should ensure that the copper rod has a length of fewer than 4 feet.
  • Copper wire. The copper wire is usually connected to the ground and is the conductive electrical wire.
  • When camping outdoors, things may go against your plan. You can use a hammer to drive the copper rod into the earth.
  • You can twist the copper wire into the copper grounding so that you will have a good connection between the two.
  • Wire strippers. The majority of generators have an insulated grounding wire. You should remove this insulation at both ends using a wire stripper. You should then attach this to the copper wire on the grounding rod and generator.
  • After stripping the ground wire completely, you can now attach it to a  generator. In most cases, you will need to loosen a nut using a wrench.

Why you should ground the generator neutral

If there is a faulty current, this will usually leave the system through the neutral and will flow into the ground. The amount of volts that a generator produces is usually very high and so is the current that is generated. This high current will damage the neutral grounding. To minimize the value, the grounding is usually connected to high resistance.

On top of this, the circuits also feature protective relays. The current value of the fault should be high to the point that evens the relay doesn’t work well. With the high resistance, the transient overvoltage is reduced.  However, it’s preferable as the resistance can harm the machine.

Steps for generator grounding when camping

Here are the steps you should follow on grounding your generator when camping.

  • Installation of the copper rod into the ground

Ensure that you have sunk the copper ground wire a minimum of 8 feet into the ground with the hammer. When you sink the rod deeply, ensure that you have a better earthing. At times, you will realize that the surface is very hard to the point that the grounding rod doesn’t penetrate well. You can pour water and wait until the ground becomes soft.  You can also try hammering the rod at an angle of not more than 45 degrees.

  • Strip both ends of the copper wire

Avoid over-stripping the wire. Ensure that most of the wire has been left bare.

  • Wrap one side of the wire with the copper rod

After fixing 8 feet into the ground, you can encase one side of the copper wire tightly around it using the pliers.

  • Connect the other end to the generator

To ground the generator, you will now need to connect the other naked end of the copper wire. Ensure that the grounding bolt is a bit loose. Wrap the wire well and then make the bolt tight again.
