So have you recently bought a portable generator? Portable generators are useful for where temporary or remote power is needed.
Portable generators are used for a spread of various tasks including copy home power supplies, powering tools at the employment site, and lots more. Specific scenarios may require you to ground your portable generator, and knowing the way to catch on and what tools you’ll need can prevent serious injury. In this article, we’ll review what grounding is, the way to tell if you would like to ground your generator, the tools you’ll need, and therefore the process of rooting your generator.
You should make sure, that you have grounded the portable generator before you start! That is if it is essential because many portable generators do not need grounding after all. Knowing when to ground a portable generator is critical for the safety of the operator.
For starters, to ground a piece of electrical equipment simply refers to connect it to the ground in order to make it safe to operate. Some people use the term “earthing” to refer to the same activity.
What Is Grounding?
Grounding refers to connecting a circuit to a reference ground. In the case of a generator, the frame of the generator acts because the circuit and a properly installed grounding rod act because the reference ground. You are connecting a copper wire from your generator’s frame to the grounding rod grounds of the generator for safe operation.
What happens if you don't ground a generator?
For a 380V generator, when a live ground fault occurs, if the generator center point is not grounded, the voltage of the other two live lines will rise from 220V to 380V, which increases the risk of personal electric shock, so it should be grounded.

- To find out if your portable generator must be grounded, the simplest way is to see your manual and see if it’s to be grounded.
- If the manual isn’t available, you’ll still make a couple of checks to make sure proper safety.
- If your generator may be a separately derived system, you’ll get to use a grounding rod.
- If it’s not a separately derived system, your generator won’t be grounded.
- To recognize a separately derived system, check the generator’s transfer switch.
- An unseparated derived system features a transfer switch that can’t be transferred to the neutral ground conductor, meaning it’ll not need a connection to a grounding rod.
- Most portable generators have their fuel tank, engine, and housing bonded to the frame, making them to where they’re going not to need to be grounded.
Is Grounding Necessary for all Portable Generators?
Safety is an important concern when it comes to portable generators. Without understanding and taking the necessary safety precautions, you or someone around you could easily get hurt or injured. Also, your generator could be prone to uncommon current flow leading to a power outage or even in some cases damage.
Back to the initial question—the answer is either “Yes” or “No”, depending on the model of the generator. As mentioned earlier, not all portable generators need grounding to be completely safe.
Generators usually fall under two categories:
-
Non-separately derived systems:
- A lot of modern generators fall under this category. They are configured in a way that eliminates the need for grounding.
- It is simply, a wiring system with direct electrical connection to conductors originating from another system.
-
Separately derived systems:
- Grounding is only essential for generators in this category.
- It is simply, a wiring system without direct electrical connection to conductors originating from another system.
How to know if your Portable Generator needs grounding?
You should check the manufacturer’s instructions to find out if your generator needs some grounding.
If you do not have those instructions on hand, then the easiest way to determine whether the grounding is required for your portable generator is to look at the transfer switch. If the switch is designed in such a way that it can be transferred to the neutral ground conductor, then the generator will need to be grounded and vice versa.
Basic Tools Required for the Grounding of Portable Generator
To be able to effectively ground your portable generator, you’ll be needing the following tools:
1. Copper Rod
A copper ground rod is the most essential tool you will need for the process of grounding a portable generator. Get a copper rod of at least 4 feet. This will serve as your generator’s main grounding material.
2. Hammer
How will you sink your copper ground rod into a hard surface? A hammer is what you’ll be needing to drive your copper ground rod into the ground fast and easily. You can also use a mallet instead, for that purpose if you like.
3. Copper Wire
Your portable generator will need to be connected to the grounding rod in order for it to be successfully grounded. How do you connect it to the rod? Connect it with the help of quality copper grounding wire.
4. Wire Strippers
You will have to remove the covering or plastic coating from both ends of your grounding wire before tying one end around the rod and attaching the other end to your generator. In such case, a wire stripper will help you strip your copper wire fast and easily. Do not try to use your teeth or nails to do the same.
Else, using a covered wire will not make any difference. Also, be careful not to over strip the wire, leaving the most part of it bare.
5. Pliers
Once you have sunk the rod into the ground, a minimum of 8 feet, it is time to wrap one end of the copper wire tightly around it. One of the most essential grounding task will be to wind the copper wire tightly around the grounding rod to enhance the connection. This is where you’ll need a quality set of pliers to do the task.
6. A Wrench
A good wrench can be very useful in attaching the copper wire to the generator by helping loosen a bolt on the portable generator for efficient connection.
How to Ground a Portable Generator?
With these tools at your disposal, it is time to get started. Here is how you can ground a portable generator properly:
- Put the copper rod in the ground
- Strip the copper wire from both ends
- Wrap one end of the wire around the copper rod and attach the other end to your portable generator
Frequently Asked Questions (FAQ’s)
How to ground the portable generator in case of hard surfaces?
Sometimes you might find that the surface is too hard to sink your grounding rod smoothly. In that case, you can pour water and wait until the ground is soft. What if the surface is rocking and pouring water on it does not help? In that case, sink the rod at a special angle. You can choose an angle that does not exceed 45°.

For how long can I expect my portable generator to last?
The answer to the question that for how long a portable generator would last, depends upon 2 factors. One is that few units are more efficient in terms of fuel as compared to others. This essentially means that they require or consume less gas which makes them last longer on being refueled for a single time. They can achieve it because of hi-tech solutions which adjust the work of the engine as per the existing consumption of the electricity.
And secondly, it is contingent on how many devices you link the generator with.
Generally, the manufacturers and the producers demonstrate the running time of a portable generator at about 25% load. Although, if you plug the electrical device which consumes all the running wattage that is available, your portable generator would be running at almost about hundred per cent load and would consume a lot more fuel as compared to normal situations.
As for rough estimates – typically you can expect a normal camping generator to last for about 6-8 hours.
Are the portable generators that are made in china any good and worth purchasing?
Truly speaking, everything is dependent on the model, speaking in general terms, yes, portable generators that are manufactured in China are reliable and worth using. A few of the more expensive models from brands like Yamaha are also manufactured in Chinese factories. Few portable generators developed in China normally have the engines that are produced under the license of Yamaha or Honda.
Hence, what you receive is essentially the similar type of hardware, however, with a lesser cost and possibly a few minor rudiments of cheaper or lower quality for example plastic finishing in some parts of the appliance instead of iron coating.
