What is a power cord called?
A power cord is a vital component of any electrical appliance. It connects your appliance to the electrical utility or power supply, and it allows you to use the appliance.
Power cords are usually made of insulated electrical cable with one or both ends molded with connectors. One end is typically a male connector or plug that goes into the electrical receptacle, wall outlet, or extension cord.
The other end is a female connector that is attached to the appliance or to another male connector. This female connector is sometimes omitted in appliances where it is replaced by a fixed cable.
Power cords are seen in both domestic and commercial areas. They are used in every electrical appliance such as TVs, computers, refrigerators, air conditioners, and so on. Industrial and manufacturing plants rarely utilize power cords since most plant equipment draws high amounts of current and requires medium to high voltages. Power cords are typically limited to current ratings of 16 A to 20 A and voltage ratings of 125 V to 250 V respectively.
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 not only see 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?
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.
