A power cord consists of three basic parts: a plug, a ground wire, and a cable. Designed to transmit electricity from an electrical outlet to an appliance, the power cord follows a set of standards, markings, and regulations around the world. While some power cords are used only indoors, others are used outdoors or in hazardous locations. Here are some tips to ensure a safe cording experience:
A power cord should have a single plug with a standard IEC 60320 code, while two outlets can have different codes. The IEC 60320 code refers to the standard for a certain combination of voltage, current, and temperature. In general, the connectors on a power cord should be C13 or C14, while C20 cords are for appliances that are made outside of the United States. These power cords are also rated for a certain temperature range, so they should be used only in countries that support those standards.
NEMA 5-15P power cords are designed for 15-amp appliances and are often fitted with a three-prong plug. Look for a plug with a shape that matches the equipment. Some plugs have flat prongs while others feature a round earth pin. While many cords have three prongs, you should choose the one that matches the purpose you’ll be using it for. They can have l1430 side-facing heads or plugs that are flush with the wall. You can also choose a power cord with multiple outlets. A power cord with three prongs is also known as a three-prong plug, and the plug may have a rewireable assembly or a fuse.
NEMA is an international standard for power cords and describes the different types of plugs and receptacles used throughout North America. It identifies the voltage capacities and configuration of plugs and receptacles used to connect household appliances and large machines. Plugs are classified into three categories according to their NEMA designations. For example, NEMA type A plugs have two blades while NEMA type B power cords have three.
NEMA 5-15P is a common type of power cord. This plug and receptacle combination is widely used in sockets. This type is rated at fifteen amps and is used most commonly in North America. NEMA 5-15P power cords are most common, while NEMA 5-15R power cords are another popular type. In North America, NEMA 5-15P power cords are often sold as NEMA 5-15P to NEMA 5-15R cords.
Locking a power cord is another way to prevent accidental disconnections. It prevents accidental disconnections due to human error or application vibration. The security of locking power cords reduces system downtime and operational costs. In addition, they help you map out the power chain by color and ensure the proper connection of devices. They are particularly useful for connecting devices to PDUs and computers. So, keep these things in mind when buying power cords.
