How Do You Choose the Right 50-Amp Generator Cord?

1. Choose Right Amps

For our case, this is pretty obvious since we're focusing on the 50-amp cord. However, this would be the first step in getting the cord right if it was not so evident. What are amps? These are the amps via which the codes are measured.

The larger the amps, the greater the electricity the cord can handle without worrying too much about it. Therefore, a 30-amp cord carries less electricity than the 50-amp one. Nonetheless, the 50-amp generator cord works great with residential and domestic requirements.

2. Choose the Right Cord Shape

As a customer, you want to get the best value for your money. That means choosing the right products. Once you've considered your current location and amps, it's time for the shape. There are 3-prong, 4-prong, straight-blade, and twist-lock options.

The choice comes down to what your generator has. For most residential generators, you'll find they have 3-prong and 4-prong cord shapes.

These often handle a maximum of 30-amps. Finally, the straight-blade and twist-lock are found for the commercial scene. These can handle 50-amps without a problem.

3. Plug-In

Once you've made these decisions and considered other related searches and everything is in order, even with the generator, it's time to plug in the cord. After that, you can double-check again to ensure that the cord is not damaged and that the generator is in good form.

If you sense that the cord is damaged in any way, better to replace it with one of our options above.
