The purpose of power cords is to transmit electrical energy to the equipment they are connected to. There are various types of power cords, including C14, C17, and C20. Some power cords are used for outdoor applications or devices with higher electrical currents. These types of cords are less common than their more common cousins. Depending on the intended use, they may require additional protection against electromagnetic interference. Before purchasing a power cord, you should know what its features are to avoid tripping hazards.

A power cord can be divided into two or three cores, depending on how many phases are in the power grid. A single-phase domestic distribution system typically requires a 2-core cable. There are two wires in a power cord: one is live (black), and the other is neutral (brown). Occasionally, a third wire is added to the cord, called a grounding or earth wire. If you want to use your cord for such sensitive equipment, it should also have a  Streamer Lights shield over the power conductors.

Historically, many different types of cords have been used in the US. Early cords were made of bare wires or cloth covered with a tar-like compound or a jute-covered copper rod. Later, manufacturers introduced armored cable, which lasted until the 1950s. Two-wire PVC-insulated cable has become a common type of cord. PVC-coated cords are heat-resistant and resistant to high-temperatures. They come in different lengths and insulations.

Buying a power cord is an important decision if you plan on using your electrical device anywhere. The length and voltage of the cords vary according to their intended use. When choosing a power cord, think about the safety of your appliances first. Different cords are rated as high-quality or low-quality, and you should look for the highest quality cord at all times. Not only will this help to ensure the safety of your electrical appliances, but it will also protect you from the potential dangers associated with electrical energy.

To ensure that you are buying a cord that will function safely in your environment, look for the ANSI-approved NEMA 5-15P plug and receptacle standards. They are widely used in North America and are the most common standard for plugs and sockets. Most NEMA cords in North America are NEMA 5-15P to NEMA 5-15R. You can also find cords with C13 plug and C15 receptacle.

Different countries have different power cord standards. IEC 60320 is the internationally recognized standard for power cord appliances. The different types of connectors used in different countries are identified by the letters “C” and can be found on the cord itself. The IEC 60320 also specifies different types of connectors for different combinations of voltage, current, and temperature. A C13 power cord can be used to connect a computer to a monitor, amplifier, or computer. A C15 cord is rated for high-temperature devices.

If you need to use power cords for a long time, consider purchasing a certified AC power supply and extension cord. These are made of heavy-duty wire, and the two-conductor plugs plug into each other at a right angle. A right-angle cord can protect your device from accidental unplugging. You should also choose a right-angle cord if your cord is in a small space. This way, you can use it for multiple devices, while still having the power to use it for multiple tasks.
