Power cords are used to connect electrical devices to a power source. They can be found in consumer electronics, information technology equipment, and hazardous locations such as outdoor areas. The wire gauge used to gauge the current and voltage of the cord depends on its intended use. The type of jacket material used to protect the wires also depends on the application. Green wires are used in North America, while yellow-striped cords are used in the rest of the world.
Power cords come in different types and are called flex, mains cable, and power connector. In essence, they connect an appliance to its power source, by plugging its ends into a wall socket or extension board. A power cord is also needed when battery-backed appliances need to connect to an electrical supply line for recharging batteries. Both direct current and alternating current cords are available. If you need to connect an appliance to an electric outlet, choose a power cord with the appropriate voltage and wire gauge.
There are many different types of power cords, including NEMA 5-15R and C13. In North America, most outlets are NEMA 5-15R. The five-15P and 15R are 3-wire circuits that are rated for 15 Amps. The C15 cord is another nema 5 15 type of NEMA power cord. It is rated for 15 Amps and is typically used for lamps. For European appliances, choose a cord that has the correct plug and receptacle combination.
The IEC 60320 standard specifies the voltage, current, and temperature requirements of power cords for appliances. Power cords made under this standard are recognized as a universal standard and are sold in most countries. The two most common connector types are C13, with both plug and socket shaped differently depending on their intended use. However, if you are using a computer or other high-tech equipment, make sure it has a power cord that meets the appropriate voltage and current requirements.
Power cords are grouped according to their voltage capacity and amperage rating. In North America, NEMA power cords have two or three prongs, and NEMA type B plugs are three-wire grounded. The CEE 7/7 standard is common throughout Europe. The CEE standards have two conductor blades and a grounding rod, while the NEMA standards have four or more. This standard determines the type of plug and socket for a particular appliance.
