A Guide to Electrical Power Cords

Our appliances work when electricity is conducted to the appliance from the main source of power through a power supply cord. Power supply cords are flexible cords that consist of two plugs on both ends. The two plugs on both ends is one male and one female plug. What connects both ends is the cable assembly which is made up of copper stands covered with insulating material such as a rubber jacket or a polymer. These copper strands conduct electricity from the main power source to the appliance. Learn more about International Cordsets, go here.

The power supply cord is permanently fixed to the electrical equipment and the power cord sets are used anywhere that electrical equipment is used. When equipment is far from the power source, extension power cords are used. Sound equipment, lighting, shop equipment, and domestic equipment usually use extension cords. In North America, there is a standards for electrical plugs, electrical receptacles configuration, and cord voltage capacities and this is the NEMA power cord. These American standards are very different from those set for the international market which is called international power cords. Plugs used in North America can only be used in international sockets with the use of a plug adapter. You can click for more info here.

In a power cord, the male plug is the one that connects to the main power source. And, the female is the plug that goes to the appliance or electrical equipment. Many places have different voltage standards and electrical receptacle configurations, and this is the reason why power cord manufacturers make power cords depending on the region and country they are making it for. Voltage and receptacles from different locations are not the same and this is why these power cords are not interchangeable. Standards in North American is not the same as international standards.

When selecting the type of power cord, you need for specific applications you need to consider many factors. The specifications set by manufacturers of power cords include the following: current rating, voltage rating, safety, jacket material, wire shape and size, length, and maximum cable temperature. Whatever your application is, then this determines the jacket materials that suits the cords best. There are jackets that are made from rubber, polychloroprene, thermoformed from PVC, and textile construction. The power supply cord or the electrical wire needed should be able to bear the amount of voltage that will pas through it; and this determine its proper size.

Power supply cords you find in the market are of different types. Gauge size, awg size, applications, jackets and insulations are different from each kind of power source. These power cords include international power cords, AC power cords, extension cords, electrical plugs, power supply cords, international cord sets, and more. Please click this link  for more info.
