Best Extension Cord For Generator Buying Guide

It is an exhausting job to figure out what kind of cord will work best with the generator.  You’ll have to check the compatibility of a cord along with a few other aspects. We chose the Top 4 best extension cords for the generator. Their features and pros and cons are also mentioned. So, you can make a decision easily.


But still, if you find it hard to select a cord, go through our buying guide. We are going to cover a few important points that you should keep in mind while purchasing an extension cord for a generator.


Important Features of an extension Cord for generator

There are a few important features that you keep in mind while choosing an extension cord for a generator. Check the gauge, length, amperage, wattage limit, plug type, and material of a cord.


The gauge of an extension Cord Generator

Gauge is another aspect that can’t be ignored. Gauge is the thickness of the wire. If you do not know much about the gauge, let us clarify it first. Gauge is measured as an American wire gauge. You should always go with a lower AWG number. A lower gauge number means that the wire will be thick. If the gauge number is high it means the wire is thinner.


As we will select a thicker wire, the gauge number should be low. It should not exceed 12 figures.


AWG 14, AWG 12, AWG 10, and AWG 8 are the standard gauge numbers.


Always go with a thicker cord, because it can handle more power.


Length of an Extension Cord for the Generator

The Length of an extension cord should not exceed 50 ft. The long cord creates high resistance and it results in voltage drops which can make a generator hotter and less efficient.


Amperage and wattage limit

Amperage and wattage limit depends on the gauge. You can check the amperage limit for three wire extension cords.

  • 16 AWG = 10 amps
  • 14 AWG = 15 amps
  • 12 AWG = 20 amps
  • 10 AWG = 30 amps


You should keep this number in your mind. Because any mistake can cause fire hazards. For example, if you use 16 AWG cords for a 15 amp device, the cord will get hot and you may face issues.


For wattage and amperage, you can get guidance from the below-mentioned table.

Extension Cord AMP Watts Volts
14/3 max. 15 1800 120
12/3 max. 20 2400 120
10/3 max. 30 3600 120

The “/3” describes the 3 wires in the extension cords’ insulation.


Plug Types

First, you need to check the home outlet type and type of jack on the generator. NEMA 1 (two-prong) and NEMA 5-15R (three-prong) are the most common outlets in the home in the USA.


After analyzing the outlet, find the cord that can match your generator’s outlet.


However, here is a pro tip; if you can’t find a cord that can be connected to your generator, use a converter and the plug type.


Extension Cord Material and type

Extension cords are made with thermoset, thermoplastic elastomer, or thermoplastic.


Each of these has its benefits.


For example, the thermoset cord is durable and has a thick rubber jacket.


The thermoplastic elastomer works well in low temperatures and the thermoplastic cord can be used for a short period.


Some cords are weather resistant and water-resistant. So, if you are planning to use a cord outside, choose a weather-resistant cord.


Security tips for using an extension cord for a generator

Keep these safety tips in mind while using a cord.

  • Make sure you connect a power cord to the GFCI outlet.
  • If you want to use an extension cord outside, make sure you have got a water-resistant cord.
