Power cords are essential for supplying power to electronic devices, such as computers. The right cord for the application should meet the necessary standards for its voltage, wire gauge, and overall construction. The cord’s design should also comply with regional electrical codes. Here are some tips for choosing a power cord. They may also come with an extra clamp to keep them in place. The power cords you buy should meet all of these requirements, and they should be tested before use.
Choose power cords that meet the standards for your country’s electrical system. Many of these cords are designed to withstand rough handling in harsh environments. These cords feature molded strain relief shrouds and large flat heads. You can also find cords with 50A or 30A plugs. Lastly, choose a cord with an NEMA rating. The UL mark signifies UL safety and meets NEMA standards.
Non-detachable power cords should have a strain relief connector. This type of cord cannot be detached, as it is hard-wired to the enclosure. The cord has a screw or post and a metallic 60 amp fuse ring that slips over it. One wire in the stripped cord is attached to the lug/ring terminal. To use a lug/ring terminal, you need an approved crimp tool. There are also some tips for preventing the cord from coming undone.
The most common power cords in the U.S. are NEMA 5-15P power cords. These cords are designed to connect a plug to a socket with a NEMA 15R plug. This cord is the most common type of power cord. A NEMA 5-15P to NEMA 5–15R power cord is another type. It is rated for 15A at 250 V and is often used in sockets.
A NEMA power cord follows the same standard for voltage and amperage as the plug that it matches. The NEMA designation is based on the National Electrical Manufacturers Association, which specifies the configuration of electrical receptacles in North America. A NEMA type A plug comes with two conducting blades, while a NEMA type B cord has an extra ground rod. There are also various other standards governing power cords, such as IEC 60320.
IEC 60320 is an internationally recognized standard for power cords. These cords are different from country to country, but they all have the same basic characteristics. A C13 cord is intended for computer applications, while an IEC 60320 power cord is made for laptops and desktop computers. The IEC 60320 standard also specifies different types of connectors based on voltage, current, and temperature. The C13 power cord is the most common type for power cords.
