A variety of power cords are available for different types of applications. They’re often used for information technology equipment, consumer goods, and outdoor applications. These cords come with different features to meet different needs, including voltage, current, maximum cable temperature, and molded plug or female receptacle type. In addition to meeting the aforementioned specifications, manufacturers can customize the construction of their cords based on their customers’ specific applications. Depending on the application, they may be constructed with different wire gauges and jacket materials. For example, a cord that’s intended for outdoor use may need to have a waterproof jacket while one placed in an area with a high level of electromagnetic interference may require an extra-thick jacket.
Power cords have changed significantly over time. The first cords used in American homes were made of bare wires. Later, manufacturers developed the Romex cable, which is a two-wire PVC-insulated cord. Aluminum wire was also used but is now banned as it is prone to corrosion. In the 1970s, the use of asbestos in cloth wire was banned. Today, many homes in the United States use three-wire PVC-insulated cables, which work with power adaptors.
Another type of power cords is a splitter. This cord connects multiple devices to a single power source. The cords are usually branching into multiple cords with receptacles on each end. This type of cord is usually used in smaller workspaces where space is limited. The splitter has a plug at one end that connects to a wall outlet. The other end of the cord is usually fitted with a molded electrical receptacle.
Power cords have become more sensitive to environmental nema 5 15 regulations, including RoHS and REACH. Power cords are manufactured from polyvinyl chloride (PVC), which has a plethora of negative consequences for the environment. Therefore, before purchasing a power cord, make sure to ask for its RoHS and REACH declarations. This is your assurance that the cord is environmentally friendly. If you’re worried about its quality, consider buying a high-quality cord.
The IEC 60320 standard for power cord appliances has international recognition. These cords have various specifications depending on country-specific plugs. The IEC 60320 standard specifies different connectors for varying voltage, current, and temperature. The C13 plug is typically the most common. In addition to the C13 connector, there are other types of power cords that differ by country. A few common examples of these cords are described below.
In North America, NEMA standards for power cords are adopted. This includes the NEMA 5-15P plug, which is a three-wire circuit rated at 15 A at 250 V. This is the most common power cord in the U.S., and there are other variations such as C15 to C13. A third type of NEMA cord is a NEMA 5-15P to NEMA 5-15R power cord.
