Is It Necessary To Use An Extension Cord For My Generator

Portable generators are extremely versatile and can be your instant and reliable source of power when your main supply source fails or while outdoors on a trip. But portable generators are not enough. You must also invest in good-quality extension cords to make sure you get the most out of your portable generators.  

Choosing the right type of generator extension cord is very important. Many types of extension cords are available on the market, so it might not be easy to choose the cords you want. Any extension cord won’t work. Not choosing the right one may even end up damaging the cord and the generator. 

Do Regular Extension Cords Work With A Portable Generator?

Regular extension cords can serve your quick-fix needs, such as plugging in a small appliance. The three-prong type cords are commonly available in any store. They can be useful, but they are not the right choice if you want to use them for a more specific purpose and not for some quick-fix solution.

It makes sense not to use conventional extension cords because they are generally incompatible with generators. They do not readily fit into the outlets. 

Reasons Why You Must Avoid Using Conventional Extension Cords

  • They are cords designed for general utility and hence may not be compatible with your generator
  • They may not meet your extension needs
  • Most cords are not made for outdoor use. If you are using a portable generator outdoors, these cords will not be of any use.

Durability is one of the main features to look for when buying a generator power cord. If your use is for indoor extension, you may invest in a light-duty version. For outdoor use, don’t compromise. Choose a heavy-duty extension cord engineered for lasting wear and tear and designed to withstand the elements. 

The three key factors to consider while choosing an extension cord for your generator are the length of the cord, the amperage rating and the gauge, and the shape of the cord. 


Most extension cords are sold in 25 feet lengths, but good quality and top branded cords can be ordered in lengths of up to 250 feet. However, it must be borne in mind that as the length increases, so will the electrical resistance it puts out. 

It means that if you want to transfer power efficiently, do not use extension cords that are longer than what you need. In other words, use the right fit. 

Gauge and Amperage

All extension cords come with an AWG or American Wire Gauge rating. It is a measure of the amperage they can handle. The cord with a low AWG will be thicker and can handle more amps. Buy cords that can match the amperage of your generator, but it is okay to go for cords with a grade lower. It can help amplify the cord’s capacity to provide generator power to any electrical appliance.

Cord Shape

One of the most commonly available extension cords is the three-prong type. You will also come across four prongs and the twist-and-lock type. Regardless of the shape, check if the cord plugs smoothly and securely into the generator and has the correct AWG rating.
