What Gauge Extension Cord for Hedge Trimmer | A Detailed Guide

Using the right gauge extension cord is important when operating a hedge trimmer. The gauge extension cord you use should be based on the amperage and wattage of your hedge trimmer, as well as the length of the extension cord.

In this guide, we will go over all of the information you need to know in order to choose the right gauge extension cord for your hedge trimmer.

What is a Gauge Extension Cord?

A gauge extension cord is an electrical cord that is used to connect a hedge trimmer to a power source. The gauge of the extension cord is determined by the thickness of the wire and is represented by a number. 

The lower the number, the thicker the wire and the higher the capacity for electrical current. For example, a 12-gauge extension cord can carry more electrical current than a 16-gauge extension cord.

What Size Extension Cord Do I Need for My Hedge Trimmer?

The size extension cord you need for your hedge trimmer depends on the amperage and wattage of your hedge trimmer, as well as the length of the extension cord. 

  • The amperage of your hedge trimmer determines how much electrical current it draws from the power source. Most hedge trimmers have an amperage between 4 and 7 amps.
  • Wattage is a measure of how much power your hedge trimmer uses. You can calculate wattage by multiplying volts by amps. For example, if your hedge trimmer has a voltage of 120 and amps of 6, the wattage would be 720 watts. 
  • The length of the extension cord you use will also play a role in determining which size extension cord you need for your hedge trimmer. The rule of thumb is that for every 100 feet of extra length, you will need to use a heavier gauge extension cord. So for example, if you are using a 100-foot 16-gauge extension cord, you would need to use a 12-gauge extension cord for an additional 100 feet, or 200 feet total. 

Choosing the Right Gauge Extension Cord

Now that we’ve gone over some basic information about gauge extension cords, let’s talk about how to choose the right one for your needs. 

When choosing an extension cord, many people only consider the length they need. However, it is just as important to choose the right gauge size. The gauge is the measure of how thick the wire is. In general, the thicker the wire, the better able it will be to handle higher voltages and currents. 

Extension cords are often used with outdoor power tools such as lawnmowers, trimmers, and pressure washers. They are also used indoors for appliances such as vacuums, hair dryers, and coffee makers. Choosing the right gauge extension cord is important to ensure that your devices can run safely and efficiently.

  • The first step in choosing the right gauge extension cord is to determine what kind of hedge trimmer you will be using with it. Each device has a different voltage and current rating. You can find this information in the documentation that came with your device or on the manufacturer’s website. 
  • Once you know the voltage and current ratings of your devices, you can consult a chart to determine what gauge extension cord you need. A good rule of thumb is to choose a cord that has a lower gauge number than the rating of your appliance or tool. For example, if you have an appliance with a voltage rating of 125 volts and a current rating of 8 amps, you would need an extension cord with a 10-gauge or lower rating. 
  • If you are still unsure about which gauge extension cord to choose, you can always ask an expert at your local hardware store for help. They should be able to point you in the right direction based on your specific needs. 

Installing the Gauge Extension Cord | The Right Way to Do It

Installing the Gauge Extension cord with your hedge trimmer is a process that is rather simple, but there are still a few things that you need to know in order to get it done correctly. We will be walking you through every single step of the process so that you will not have any trouble at all when it comes time to do it yourself.

  1. The first thing that you need to do is make sure that you have all of the necessary tools and materials. You will need a screwdriver, a pair of pliers, and an extension cord.
  2. The next thing that you need to do is locate the screw holes on the side of the trimmer. Once you have found them, use the screwdriver to remove the screws.
  3. After the screws have been removed, you will then need to take the cover off of the trimmer.
  4. Once the cover has been removed, take a look at the inside of the trimmer. Locate the wire that goes to the motor and disconnect it. The wire should just pull right out.
  5. Now take a look at the end of the extension cord and locate the black wire. Cut this wire off so that there are about 2 inches of it remaining. Strip 1/2 inch of insulation off of this wire using the pliers.
  6. After this has been done, twist this wire around one of the terminals on the motor. Make sure that you twist it in a clockwise direction so that it tightens as you twist it. 
  7. Take a look at the other end of the extension cord and locate the green wire. Cut this wire off so that there are about 2 inches of it remaining as well.
  8. Strip 1/2 inch of insulation off of this wire using the pliers as well. After this has been done, twist this green wire around one of the terminals on the trimmer. Make sure that you twist it in a clockwise direction so that it tightens as you twist it.
  9. Now that the extension cord is connected to the trimmer, reattach the cover of the trimmer and screw it back into place. Now, your gauge extension cord is installed correctly and ready to use with your hedge trimmer.

Be sure to check all of your connections before you plug it in and you should be good to go! 

The Bottom Line

You should always make sure that you use the right gauge extension cord when plugging in your devices. This is especially important with Hedge trimmers as they require more power than other appliances or tools. 

By following these steps, you can ensure that your trimmer will be powered correctly and safely. Good luck!
