What is a power cord called?
Power cords are the electrical components used to connect appliances to an electrical transformer or power supply. They typically have a male connector at one end, which plugs into a wall outlet, extension cord, or another electrical component. The other end has a female connector that is attached to the appliance itself.
Power cords can be found in just about every home and business across the country—they're used in everything from televisions and computers to refrigerators and air conditioners. In industrial and manufacturing settings, power cords are usually limited to current ratings of 16 A or less and voltage ratings up to 250 V because most plant equipment draws high amounts of current requiring medium to high voltages.
What is a power cord used for?
A power cord is a cable that connects your computer or another device to the wall outlet in order to use it.
Power cords are used with laptops, desktop computers, monitors, printers, and other electronics. The power cord has two ends: one that plugs into an electrical outlet and another one that connects to your device.
The number of pins on each end depends on the voltage requirements of your electronic device. The type and size of pin connectors used in your country will determine which power cord you need for your product. Some devices require different types of connectors for different voltages (called splitters), so you may need more than one power cord for some devices.
Amps and watts in power cords
So you've got a new appliance, and you're ready to use it. But before you plug in that power cord, make sure you know what kind of cord you need.
The name of each of our Certified Appliance Accessories dryer and range cords includes the amps. For example, if you take a look at our range cords, you'll see not only the reference to 3 wire or 4 wire but also the amps.
For the appliance power supply and extension cords that plug into standard wall outlets, you'll see amps in the item name and watts down in the specification bullets. Those two numbers will help you figure out just how much the cord can handle.
For example, the 10-amp cords can handle up to 1,250 watts. The 13-amp ones handle up to 1,625 watts, and the 15-amp ones handle up to 1,875 watts. Those numbers are based on 125 volts as a precaution.
Those cords can also be purchased separately. And if, for some reason, you need to extend the reach of an existing power cord or simply want to make a hidden outlet more accessible.
What is inside a power cord?
A power cord consists of a plug, the cordage and a strain relief connector to secure the cord to the device. The hard-wired power cord consists of a plug, the cordage, and a strain relief device to secure the cord to the equipment enclosure. The detachable power cord also known as a power cord set, consists of a plug, cordage, and a connector or receptacle.
Furthermore, you can plug an extension cord into an outlet if it is designed for outdoor use. Do not plug an extension cord or power strip into it. You can buy a power cord for your television if it is still under warranty or replace it yourself if you have some basic electrical skills.
How do you plug in a power cord?
Power cords consist of a core of metal wire offering good conductivity, such as copper or aluminum. The core is surrounded by other material layers, including insulation, tapes, screens, and armor for mechanical protection. These additional layers are designed principally to allow the metal core to continue to conduct electrical current safely in the environment it is installed.
A good conductor is made of a material whose atomic structure has loosely bound electrons in its outer shell, which can move across the atomic matrix of the material. On the contrary, good insulators have tightly bound electrons which make it difficult for this current flow.
How do you plug in a power cord?
You can buy a universal power cord that will fit many different electric tools. They do exist, and they are part of the reason why we offer these cords on our website. If the buyer has a powerful tool that uses several types of plugs, but most are US-style at one end, then it is best to buy the right type of cord for this area.
It is also possible that certain manufacturers make two- or even three-pronged power cords that only fit their products. In this case, it might be necessary to check with whoever made your product to ensure that he or she recommends using the cord you need by checking old ones first.
