What type of extension cords should be used with generators?

Using heavy-duty, outdoor-rated cords with generators is essential for several reasons. Generators can produce higher voltages and currents, which require cords that can handle the electrical load without overheating or becoming damaged. Heavy-duty cords are designed with robust insulation and thicker gauges to ensure they can safely carry the amount of power needed for tools and equipment connected to the generator.

Outdoor-rated cords are resistant to the elements, including moisture, UV radiation, and temperature fluctuations, making them suitable for outdoor use where generators are typically operated. These cords also often have additional features such as reinforced connections and weather-resistant sheathing that enhance their durability and safety in various environmental conditions.

The other options do not meet the necessary safety and performance standards required when using generators. Light-duty cords, for instance, are often not able to handle the higher power output and can lead to overheating and potential fire hazards. Household cords typically lack the robustness and durability required for outdoor environments, and cords that are visibly damaged pose significant safety risks by potentially causing electrical shock or fire risks.
