Extension cords are used to extend electrical cables, allowing for the powering of electrical appliances and other equipment. They are available in various sizes, lengths and features. However, they can be dangerous if not used properly.
The safety of extension cords depends on the wire gauge, the length, and the amperage rating. For example, light-duty extension cords are usually safe for use with lamps, clocks, and other items with a low power demand. On the other hand, heavy-duty extension cords are more suited for devices with a high power consumption.
There are also extension cords that have special features, such as GFCI protection. These cords help to prevent shock hazards by protecting the wires from arcing and tripping.
Before purchasing an extension cord, check the owner's manual. Usually, the wattage is listed. Choosing the right cord for your needs will ensure a long life.
Using an undersized extension cord can lead to overheating, which can be a serious fire hazard. When using an extension cord outdoors, be sure to connect to a GFCI-protected electric source.
In addition, keep your extension cord away from wet surfaces. It can be damaged by water and dust. Be sure to check it periodically to ensure its integrity.
Extension cords come in different colors. You can choose from green, brown, and orange. Besides, there are extension cords with multiple outlets. Many contractors purchase several cords with varying lengths to suit different jobs.
A basic household extension cord usually contains 16-gauge wire. Thicker wires are better for heavier loads. Thinner, round, low-gauge cords are suited for smaller appliances.
