Heavy-Duty Extension Cords
JHL Industries’ Heavy-Duty Extension Cords

Heavy-Duty Extension Cords are important in any situation, especially involving construction and remodeling. Wherever there are power tools, there are extension cords. Knowing the correct amperage and gauge wire needed to complete a project can be tricky, but JHL Industries’ helpful guide directs you to the appropriate gauge cord to complete the job safely and efficiently.


If you use an improper gauge, equipment and tools will not receive the proper voltage needed to perform properly. The wire could melt because of the large amount of current flowing through it, compared to how much the cables can handle. The smaller the wire diameter, the higher the resistance. High resistance creates heat. Heat creates fire hazards which are highly undesirable and difficult to extinguish. The chart below offers a general guide to the gauge cord needed for certain job types and various situations.
