Buying Guide

Source: The PowerSourceHub

When buying an extension cord for your generator, you should keep the following in mind:

1. Know the wattage of your generator before purchasing a cord. Ensure that the wattage of the cord is at least equal to the wattage of your generator.

2. Choose an extension cord with a thick, heavy-duty cable. This will ensure that the cord can handle the high wattage of the generator without overheating or getting damaged.

3. Make sure the cord has the right type of plug for your generator. Different types of generators require different types of plugs.

4. Look for cords with a ground-fault circuit interrupter (GCFI) plug. This will help protect you from electric shocks and damage to the generator.

5. Inspect the cord for any signs of wear or damage before use. If the cord looks worn or frayed, do not use it with your generator.

6. Ensure that the cord is rated for outdoor use. This will help protect the cord from the elements.

7. Buy an extension cord that is long enough to reach the distance you need. Do not buy a shorter cord and try to link multiple cords together, as this could cause a fire hazard.
