In consumer electronics and information technology equipment, power cords are an essential tool to connect devices. Many cord sets are made for outdoor use or in hazardous locations. These cords are often designed with a conductive wire made of copper and insulated with a insulating material. Typically, the wire gauge used in cord sets is green, while those in the rest of the world have yellow stripes. In the U.S., power cords must comply with NEMA regulations for voltage capacity and electrical receptacle configuration.
AC power cords conduct electrical power using alternating current (AC) in a sinusoidal waveform. Typical electrical outlets use this format. You can also buy custom power cords for special applications. These extend the connection between an appliance and an electric utility. They have a socket connection at one end and an electrical plug at the other. Whether your application requires a power cord that is AC or DC or a hybrid of both, make sure it’s rated for that type.
Cords have come a long way since their invention. The first power distribution systems were created in 1882 by Thomas Edison. The first electrical cords were made of bare copper wire that were wrapped in jute and stapled. The next generation came along and introduced armored cables and three-wire PVC-insulated cable. Both of these l14-30 cables worked with power adaptors and are considered safe. And today, cords come in various insulation types and lengths.
International standards for power cords include IEC 60320, a standard for appliances worldwide. While different countries use different cord standards, the 60320 standard is widely accepted around the world. It specifies various types of connectors, voltage, and temperature. The connectors that comply with the IEC are marked with a “C” and are labeled with a standard code. And because countries use different cord types, it’s best to choose a power cord with the same rating for your device.
A typical power cord consists of two parts: a plug and a receptacle. Most outlets are NEMA 5-15R, which is the most common type of power cord in North America. The NEMA 15P to NEMA 5-15R cord is one of the most common types. And a C13 to NEMA 5-15P cord is another common type. When purchasing a power cord, consider the receptacle.
There are many different kinds of power cords available. NEMA stands for National Electrical Manufacturers Association, and describes different connectors that are commonly used in North America. The NEMA standards for plugs and receptacles are based on these ratings. Different plug types are designed for different amperages and voltages. And there are also different types of cords for household appliances. It’s important to choose the correct cord type for your particular device.
