Frequently Asked Questions

How many volts is a heavy-duty extension cord?

A heavy-duty extension cord typically supports 120 to 240 volts, depending on its design and intended use. These cords are built to handle higher voltages for powering large appliances and industrial equipment. Always check the cord's specifications to ensure it matches your power needs.

What is the maximum power for an extension cord?

The maximum power an extension cord can handle depends on its gauge and length. Generally, heavy-duty extension cords can handle up to 15 amps, which translates to about 1,800 watts at 120 volts. Always refer to the manufacturer's guidelines to avoid overloading the cord.

What gauge is a heavy-duty power cord?

A heavy-duty power cord typically uses a gauge of 10 to 12 AWG (American Wire Gauge). The lower the gauge number, the thicker the wire, which allows it to carry more current safely. This makes it suitable for heavy-duty applications like power tools and large appliances.

Do heavy-duty extension cords use more electricity?

Heavy-duty extension cords do not use more electricity; they simply provide a safer and more reliable way to deliver power to high-demand devices. The amount of electricity used depends on the devices connected to the cord, not the cord itself. Using a heavy-duty cord can help prevent overheating and reduce electrical resistance.

What is the difference between NEMA C13 and C14?

The NEMA C13 and C14 connectors are commonly used for computer and networking equipment. The C13 is a female connector that plugs into devices like computers and monitors, while the C14 is a male connector that plugs into power sources like power strips and wall outlets. Both are designed to handle up to 10 amps and 250 volts.
