Power cords have three important components. These cords are the universal conduit that transports electricity from the power outlet to your product. As such, they are subject to numerous international standards, markings, and regulations. Listed below are the characteristics of a power cord. These features can help you determine the safety of a cord, and ensure that it meets the highest safety standards. Also, be sure to check the plug pattern. Some cords have a different plug pattern than others. If you are unsure, use a guide published by Interpower.
First, know what you are buying. Many types of cords have different plug and receptacle specifications. C14 cords, for example, have 60 amp fuse a C14 connector. C17 cords, on the other hand, lack a third pin for grounding. They are rectangular and designed to provide higher electrical current to devices. These types of cords are less common than their predecessors. They are also available in different lengths and insulation.
Another type of power cord is the flex type, which is usually detachable from the device. These cords often come with a female connector so that kids cannot accidentally stick objects in the socket. Retainers, on the other hand, help keep the cord securely attached to an appliance. They can also be twist-locked or have other attachments. Some cord sets have accessories like fuses for overcurrent protection, leakage current detectors, and pilot lights.
Power cords come in two or three cores, depending on the number of phases. Domestic distribution systems typically use two-core cables. In addition to the two cores, there is an additional wire that is slightly smaller than the others and is called the earth wire. In North America, ground wires are usually green, while green and yellow-striped ones are used in other countries. To minimize the risk of electrocution, ensure that the power cord meets NEMA standards.
If you’re not sure how to choose a power cord, check the gauge rating of the device you’ll be connecting to it. You’ll want to go for a cord with the lowest AWG number, as the lower the number, the thicker the wire. A high-quality power cord will also save you from repairs and other electrical hazards. Its gauge rating will determine the voltage level of your device. Ensure that your power cord matches the gauge number and the electrical outlet, and it will work for your appliances.
While there are several types of power cords, the most common type is the IEC 60320 standard. This international standard defines a variety of voltages, currents, and temperatures. A cord of this standard has both a male and female connector, which connect to your device and an electrical receptacle. The cord can range anywhere from two meters to ten meters, depending on the standards used to manufacture it. It is also important to choose the right voltage and current for the device you’re connecting.
A power cord that is locked can be helpful for machines that require specific movements. An A-lock cord prevents accidental disconnections, especially with heavy machines. A V-lock cord also provides a strong connection and has a yellow release mechanism that cannot be undone by human error. In addition, an IEC-lock power cord is beneficial for devices with IEC-specific inlets, such as medical equipment or broadcasting equipment.
