When buying a power cord, make sure you choose one that meets the requirements of the country you live in. Most of the time, power cords are made of polyvinyl chloride (PVC). The increasing number of environmental regulations worldwide have had a profound effect on PVC, and you should ask to see the manufacturer’s declarations of compliance with RoHS and REACH. If it doesn’t, you should avoid buying it.
There are many different types of power cords. These include cords that are permanently fixed to an appliance and those that can be removed for storage. The former are usually made with a female connector to avoid the possibility of a live pin slipping out. Some cords come with twist locks or other attachments to prevent them from being detached while in use. Cord sets may come with additional accessories, such as fuses for overcurrent protection and a pilot light to indicate voltage. Power cords for sensitive equipment may have additional features, such as a shield covering the power conductors to prevent electrocution.
When choosing a power cord, make sure to look for the gauge rating. This measurement refers to the wire gauge used and is a very simple number. Twelve AWG is a 120-volt cord, and any cord with a lower number indicates a thicker wire. Longer power cords are less capable of carrying the same load as shorter ones. The gauge size of the wire determines how much hand lights current can be carried. A longer cord will cause a greater voltage drop and lower capacity. The opposite is true for shorter power cords.
NEMA cords are made to be compatible with a variety of plugs and sockets. The most common NEMA cord is the one that connects a C13 receptacle to a NEMA 5-15P plug. NEMA 5-15P to C15 is another popular type. If you have a C13 receptacle, you need to select a C13-style power cord. You can even purchase a NEMA 5-15P power cord to meet the specifications of your appliance.
NEMA 5 is the most common family for plugs and receptacles in North America. The current rating for an NEMA 5 plug is twenty-amps. A NEMA L14-30P plug fits a NEMA L6-30R receptacle. A hospital-grade power cord comes with a hospital-grade plug, which has been evaluated to a higher standard than non-hospital-grade cords.
If you plan on using your cords in a business setting, it’s a good idea to choose locking power cords. These cords can help protect your technological infrastructure and prevent accidental disconnections. They come in different colors, so you can map out your power chain. If you’re worried that employees will disconnect them while working, consider purchasing locking power cords. They are worth the money and protect your business’s technological infrastructure.
The IEC 60320 standard is an internationally recognized standard for power cords. While countries use different standards for these, this international standard is recognized by most. Power cords with the IEC 60320 standard are labeled “C” or “C13” and are used for computers. The IEC 60320 standard specifies various types of connectors for different combinations of voltage, current, and temperature. You’ll find different types of connectors on different outlets and in various countries.
