You may have seen power cords in your domestic or commercial environment. Almost every electrical appliance in your house uses a power cord. However, they are not used in industrial applications, which require very high voltages and currents. Most power cords are only rated for 16 A or 20 A, or 125V to 250V. However, manufacturers can customize them to meet your exact needs, according to the application. For instance, if you need a cord for rugged outdoor use, you may want to choose one with a waterproof jacket. Similarly, if you are using a power cord in an area with high electromagnetic interference, you may want to specify a cord with a special shielding.
A power cord has three components: a flexible cord, electrical connectors on both ends, and a plug cover. These pieces plug into the wall socket, an extension board, or the appliance receptacle. The power cord is used to power both battery-powered and electric appliances, as well as to recharge a battery. Several international standards and regulations govern power cords and have made them mandatory for many home appliances.
Modern power cords are regulated by a number of environmental regulations. Known as RoHS and REACH, these regulations help keep electrical equipment safe for human health. PVC, the material most commonly used for cords, has been banned from many countries because it causes corrosion. RoHS and REACH nema 5 15 regulations help protect the environment, and the growing environmental consciousness is reflected in power cords. To avoid any potential danger, you should always ask for RoHS and REACH declarations from any power cord manufacturer.
Because the global market is increasingly diversified, manufacturers must make sure they understand the different voltage and frequency standards for their products. This is because power cords are not uniformly recognized in all countries. Therefore, it is important to choose a cord that meets the specific standards of the region in which you will use it. Further, you should check the safety rating of the cord and ensure that it passes the relevant tests and certifications. The same rule applies to the length of the cord.
Several countries rely on the IEC 60320 standard for power cords. These cords vary by voltage, current, temperature, and connectors, depending on which country you’re in. The C13 power cord, for example, is the standard for power cords that are used in computer and laptop applications. Its electrical specifications are specified by IEC 60320, and the C13 connector is the most common type for computers and laptops.
When it comes to plugs, NEMA 5-15P power cords come with three prongs on the end. Choose one with a connector that matches your purpose. You can choose a side-facing head or a plug that is flush with the wall. You can choose one with multiple outlets, and you can even buy a multi-outlet power cord. Generally, these cords have three wires – hot, neutral, and ground – and 15A at 250V.
