When it comes to choosing the right power cords, you should consider the environment in which they’ll be used. Indoor environments with temperature control and a dry atmosphere are ideal for power cords. Cords for partially enclosed applications are especially durable. Plugs are generally straight, but you can find cords with right-angle plugs for those small spaces. The right-angle plug will prevent excessive cable wear. Keeping power cords out of harm’s way will help keep your business and technological infrastructure running smoothly.
Modern power distribution systems began in the 1880s, when Thomas Edison coiled jute around a copper rod and inserted it into a pipe filled with bituminous substance. His device would serve as the blueprint for modern power cords. Edison’s cords would have different insulation levels depending on their temperature ratings, and the type of appliance they would be used with. While there are now many different types of power cords on the market, they all share some common characteristics.
The plugs on power cords are UL-listed and certified to a standard. In North America, UL 498 is the standard and CSA C22.2 no. 42 outlines the requirements for power cords. UL and CSA are two certification agencies that test and certify cables. In Europe, the EN 60779 standard is used, and cables containing hand lights it are labeled with a HAR (harmonized approval).
A power cord has three basic components: a ground wire, a conductor, and a plug. These components work together to carry electricity from the power outlet to a product. They are subject to international standards, regulations, and markings to ensure safety. Listed circuits are required for certain products. If you’re in doubt, contact a reputable company with a proven track record. There’s no better way to avoid buying a defective power cord.
Power cables can be fixed to an appliance or detachable. If the lead can be removed, it’s important to choose a plug with a female connector to prevent a potential hazard of a live pin protruding. Other cords come with twist-locking features or other attachments. A power cord set may contain other accessories such as fuses for overcurrent protection, a pilot light to indicate voltage, and a leakage current detector.
Several countries have their own power cord standards. The IEC 60320 power cord is one such international standard. While countries across the world use different standards, the standards are generally recognized. Power cords that meet this standard will have a “C” label on them – which stands for “code standard”. Depending on how you use a device, the type of connector will determine whether it’s safe to connect to a given outlet.
Plug patterns vary depending on country of export. You can learn more about plug patterns by consulting a guide, such as the Interpower Guide to Worldwide Plug/Socket Patterns. You can also look for a cord with a Japanese approval symbol. If you’re not sure what plug pattern you need, consider buying a cord that comes with free technical support. And, don’t forget to check the label for authenticity! If you’re unsure, ask the retailer where you bought it.
