Power cords provide convenient ways to power electronic devices. These cords are used in consumer electronics, information technology, and outdoor or hazardous locations. Unlike extension cords, which use different voltages and frequencies, power cords are generally not affected by extreme temperature or moisture. They are made from durable materials such as nylon, plastic, or woven fabric. To avoid electrical shock, some cords have a built-in arc fault protector.
Power cords come in different sizes and shapes. Standard power cord sets include a flexible cord with electrical connectors at both ends, a plug, and a plug cover. The cord is made from highly conductive wire and is insulated by insulative material. A protective outer jacket covers both sides of the cord. One end 60 amp fuse of the cord is attached to a molded electrical plug, while the other ends are typically fitted with a receptacle.
NEMA standards are widely adopted across most countries in North America. The most common is a NEMA 5-15P plug and receptacle. Both plugs and sockets are three-wire circuits with a maximum current rating of 15 A at 250 volts. The most common type is a NEMA 5-15P to NEMA 15R power cord, and there are also NEMA 5-15P to C13 power cords.
The IEC 60320 standard for power cord appliances has international recognition. While many countries use different standards, the IEC 60320 standard is a universal standard. The standard specifies different types of connectors for various voltages, currents, and temperatures. Depending on the type of device, different power cords are designed for specific country needs. If you are considering buying a power cord for your next computer, make sure you read the label carefully.
If you need assistance choosing the right cord set for your equipment, you can refer to the Interpower chart. This chart displays the different configurations allowed by different countries, such as North America and the international market. You can also check the International Cord Set Configurations chart for information regarding the compatibility of your cords with your equipment. The Interpower cord sets are designed for international use and North American use. Besides offering international cord sets, it also offers value-added services.
The ground pin should be the first thing you look for while plugging your device. Some plugs use a third pin to ensure a connection to earth. The ground pin protects the equipment and the user from any damage due to a failure in the insulation. It is also useful for medical staff and equipment with white goods or double-insulated wiring. When in doubt, ask your electrical contractor or electrician about what type of wiring you have. These devices are usually categorized by their amp ratings.
