FAQs
How often should you inspect an extension cord?

Extension cords are pieces of equipment that encounter frequent wear and tear on jobsites. It is critical that you thoroughly check your extension cords every three months and give your cord a quick inspection each time before plugging it into a power source.

Are extension cords waterproof?

Outdoor-rated extension cords are typically encapsulated in bright orange protective sleeves that are weather resistant. However, it is important to check with the manufacturer to ensure your cable has the proper insulation. It is always a good idea to avoid getting electrical equipment wet.

What gauge extension cord do I need?

To determine what gauge extension cord you need for a project, you must first add up the total wattage of the equipment you will be powering. Then divide that number by 110, which is the standard household voltage. This will give you an estimate of the cord gauge required.
