What is a power cord called?
A power cord is an electrical component that connects your appliance to the wall outlet. It's made of an insulated electrical cable with one or both ends molded with connectors. One end is a male connector that goes into the electrical receptacle, wall outlet, or extension cord. The other end has a female connector attached to your appliance or another male connector.
Power cords are used in every kind of electrical appliance—TVs, computers, refrigerators, air conditioners, and more! They're also used in both domestic and commercial settings: you'll find them in homes and businesses alike. And they come in all kinds of sizes: from 16 A to 20 A and 125 V to 250 V respectively.
What is a power cord used for?
A power cord is a cable used to temporarily connect an appliance to the mains through a wall outlet or extension cord.
Power cords are often used with appliances in countries different from those in which they were designed and manufactured. For example, if you have an HP computer purchased in the United States that will have an incompatible power cord when used in another country, it is convenient to have a universal power cord. Even hair dryers purchased in the United States are not compatible for use in Europe; you will find that the numbering and size of outlets simply do not match.
Products include computer AC power cords and splitters and appliance/indoor/outdoor extension cords.
Amps and watts in power cords
If you're wondering how much power your appliance can handle, it's easy to find out. Simply look at the item name or specification bullets on the cord you want to buy.
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.
In our Certified Appliance Accessories dryer and range cords, 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 maybe just want to make a hidden outlet more accessible), please note that extension cords should not be used as permanent installations!
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 are an important part of any electrical system. They provide a low resistance path for the current to flow through. Power cords consist of a core of metal wire offering good conductivity, such as copper or aluminum, along with other material layers, including insulation, tapes, screens, armoring for mechanical protection, and sheathing. These additional layers are designed principally to allow the metal core to continue to conduct electrical current safely in the environment it is installed.
How do you plug in a power cord?
All power cords are not created equal. If a wall-mounted socket or socket on an appliance does not have a three-prong plug, the power cord that connects the appliance to it may not be interchangeable with other appliances with those plugs. Some three-pronged plugs are unavailable in other countries, and some two-pronged plugs are available in both U.S. and Canadian versions (one model of each), but not all countries allow them. Aftermarket adapters may be required in certain cases if the outlet is physically unable to support a particular style of plug.
