Power cords are portable pieces of hardware used to connect appliances to power sources. They are used to supply electricity to devices such as computers, appliances, and other electrical equipment. These cords can be of various lengths and are made from either direct current or alternating current. Typically, power cords come with a molded plug that connects to an electrical outlet and a socket on the other end. However, they can also be bare wires.
When choosing a power cord, you should consider the voltage of the country where you live. The plug pattern may be different from your country, so use the Interpower Guide to Worldwide Plug Patterns to find out what type you need. The plug patterns in North America and Japan are similar, but the former does not carry the Japanese approval symbol. When in doubt, choose the cord that is made of higher quality. The higher the quality of the cord, the more protected your appliances will be.
Whether the power cord is intended for outdoor or indoor use, there are a number of standard regulations that govern its construction. Typical regulations cover voltage, maximum cable temperature, jacket material, and molded plug and receptacle type. Manufacturers can also customize the typeof cord based on application requirements. The gauge of the wire will depend on the type of device. In North America, ground construction string lights wire is usually green, while yellow stripes are common in other countries.
The plug used on one end of a power cord is commonly a Type B electrical plug. It has three protruding pins – two flat current-carrying pins and a round earth pin. The plugs match the openings of the sockets. They may also have a fuse or rewireable assembly. This information is important for identifying the right cord for your needs. Further, power cords come in different insulations and sizes.
A power cord is essential for connecting an appliance to a power supply. These cords are available in a wide variety of styles, from detachable cords to permanent ones. These cords are usually characterized by their re-useability. They may even be re-wireable if they are made of high-quality materials. The features that make them so useful include the following:
RoHS and REACH regulations have had an impact on power cords. These regulations, which regulate the use of certain chemicals in electrical equipment, have a substantial impact on power cords. Most cords used in power cords contain polyvinyl chloride (PVC) – a substance that is banned from being exported and widely used. Therefore, it is important to check for these labels before purchasing a power cord. These certifications are proof of compliance with the rules.
IEC 60320 is an international standard that defines the types of plugs and receptacles that can operate at the same voltage. Each country has its own standards for power cords, but they are generally recognized as universally compatible. IEC 60320 defines several types of connectors, based on voltage, temperature, and country-specific plugs. The two most common connectors are C13 and C14. They are both compatible with computer desktops and laptops.
