The term power cord can refer to a variety of different cords that connect appliances. The cords are made of three basic components: a cable, a plug, and a connector. The cords themselves plug into a wall socket, extension board, or appliance receptacle. Cords are needed for battery-backed and power-backed appliances. They carry either direct current or alternating current. To ensure their safety, these cords are rated to handle the highest possible electrical current.
Power cords are commonly used in consumer products, information technology equipment, and hazardous locations. They come in various lengths and plug types to meet varying power needs. Many cords come with a ground wire that matches the color and configuration of electrical receptacles. To ensure that your cords meet these requirements, ask the retailer to provide a RoHS or REACH declaration. You can then purchase cords that comply with these environmental standards.
Manufacturers introduced different styles of cords for different applications. The first was Romex cable, a two-wire PVC insulated cord. Aluminum wire, which was once considered a cheap substitute for copper, was then banned Streamer Lights because of its corrosive nature. Currently, many American homes use a three-wire PVC insulated cable that works with power adaptors. If you’re not sure which type of cord is best for your application, consult a professional electrician.
NEMA is the standard for electrical cords in North America. NEMA identifies different types of plugs and receptacles. For example, a NEMA 5-15P to NEMA 5-15R cord is a typical choice. However, other types of power cords are also available. However, make sure you check the specifications of the device you’re purchasing before purchasing one. It’s important to understand that NEMA standards are not universal, and some cords are not meant for use in all countries.
A non-detachable power cord is hard-wired to the enclosure of the equipment it powers. You can easily remove the connector from the enclosure, but it is not recommended for equipment that requires hard wiring. If you’re using a flexible power cord, make sure that the device you’re using allows you to remove the cord. This is required by the National Electric Code. This way, you can avoid any electrical problems associated with the cord.
Another important factor to consider when purchasing a power cord is the voltage. The IEC 60320 standard is recognized worldwide. Most countries have a different voltage standard, but most recognize the requirements of the IEC 60320 standard. Depending on the voltage, temperature, and type of connector, the cord may be C13, C14, or C20. The “C” designation is the code standard for a variety of connector types. In addition to voltage, it specifies different temperature ratings and the type of coupler.
