The 2019 Buyer's Guide to The Perfect Generator Power Cord

Every generator puts out a specific amount of power and features an outlet unique to the unit itself. What you'll be powering and how many appliances are running determine what power and extension cord you need. The electric cord that carries power to your television, stove, heater and other electronics needs to have the right plug, the right length, and the correct gauge to suit the amperage and distance. Let us take a look at everything that you need to know to find the best performance and value. Here is the 2019 buyer's guide to the perfect generator power cord so that you know the difference between what you need for a TV power cord and the main cable that runs power from a generator outside.

Generator Power Cords: An Overview

For household backup generators, the most reliable choice is NEMA L14. It is three-poled with a standard ground connector. It's rated to 125/250 V.Its generally installed in just about every household receptacle in North America. The L-14-20R handles up to 20-amps, which is the standard outlet used by most portable generators. Make sure that you pick the right plug and cord for your generator. Always try to get an identical match as you don't want voltage loss to affect the operation of your connected appliances.

L14-20R and L14-30R

Specific generators supply a four-prong L14 outlet which allows you to connect two 120V circuits, effectively supplying 240-volts out. You find the L14-20R on generators under 5000-Watts and the L14-30R on generators above 5000-Watts. Make sure that you pick the right generator power cord for your individual needs and outlet.

Determining the length and size of the appropriate power cord?

The thinner your generator power cord, the more resistance the flow of electricity has. As the length of your generator power cord increases, so does the resistance. The resistance of a power cord is reduced by making the wire either shorter, or thicker. Picking the right power cord is critical to making sure that the electrical power supplied to your appliances is consistent without having to suffer much resistance. The amperage of a thicker generator power cable is higher, which allows it to send more amps. If you're using a top amperage generator, then you need a thick power cord. Make sure that the amperage of your cord meets the amps of your generator - for example, a 50-amp outlet needs a 50 amp power cord.

Does Plug shape matter?

The shape of your power cord plug will vary depending on the overload protection. You get 3-prong and 4-prong plugs. 3-Prong plugs carry 120V while 4-prong plugs accommodate 120V or 240V. Make sure that you check the voltage that your appliances need before buying a power cord. A generator will allow you to use either, but your devices will tell you what shape of plug you need. There are also twist-lock and straight-blade plugs available.

Basic safety precautions for a generator power cord

If you opt for an electrical cord that's got multiple ends then make sure that you don't overload your outlet. Just because you can run various appliances or tools, this doesn't mean that it is suitable. Always check the amperage. Another essential precaution is to avoid using a male to the male cord to extend your cabling. They're not safe and are not recommended for use. Maintain general extension cord safety, and don't daisy chain your leads to make your appliances reach your generator. If you are running an outdoor generator, then make sure that you get yourself a long enough cord. The most extended power cord that you can have is a maximum of 100-feet. It's due to safety standards that are regulated and enforced by OSHA - Occupational Safety and Health Administration governed locally. 75 or 100-feet may seem a bit much, but keeping the fumes away from your family is crucial. Don't run a generator in an enclosed space ever.
