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 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
When you're choosing a power cord for your dryer or range, you want to make sure that it's strong enough to handle the load. That's why all of our appliance accessories come with the amps clearly marked on the label.
And if you're looking for an extension cord that can handle a heavy load, look for one with an amp rating that's higher than what your appliance requires.
For example, if your dryer requires a 15-amp power cord, then it's safe to use an extension cord with a 25-amp rating. But if you try to plug a 10-amp extension cord into a 15-amp dryer outlet? That could cause a fire because there isn't enough electricity flowing through the wire to keep things cool and safe.
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.
