If you own a computer, you’re probably familiar with power cords. Whether they’re fixed to the wall or detachable, these cords provide the electricity your computer needs to operate. Power cords are subject to various international standards, regulations, and markings. If you have any concerns about the safety of your power cords, check with the manufacturer before purchasing. They can be tricky to identify, but with a little knowledge and care, you’ll find the perfect cord for your needs.
First of all, you should know that power cords can be 2-core or three-core, depending on how many phases they have. Single-phase domestic distribution systems typically use 2-core cable. This type of cable has a black live wire and brown neutral wire. There’s also an additional, smaller wire called the earth or grounding wire. This is a green wire that is connected to the electrical outlet. In order to avoid problems Streamer Lights with your cord, look for a company that has RoHS and REACH declarations on their power cords.
IEC 60320 is the international standard for power cords. Different countries have different standards, but the IEC 60320 standard is widely recognized around the world. Most of the time, the connectors used in power cords will have the “C” code standard. This code standard is used to distinguish different types of connectors, including those designed to operate high-voltage devices. For example, an IEC 60320 C13 cord will work with most desktop computers and will not affect other electrical devices, such as laptops.
Most North American power outlets follow the NEMA standards. NEMA 5-15P plugs and NEMA 5-15R receptacles are commonly used in sockets. They are three-wire circuits rated at 15 A at 250 volts. The most common type of NEMA power cord is NEMA 5-15P to NEMA 5-15R. A C13 cord is another common one. They can also be NEMA 5-15P to NEMA 5-15R, so that the plugs and receptacles match.
NEMA power cords come in many types and sizes. The NEMA ratings are for the various voltage capacities and amperages. The NEMA types A and B are most common in North America, and they come with grounding rods. In Europe, CEE 7/7 power cords are common. These cords are used to connect large machines to home appliances. And the NEMA standards also govern which plugs are used with different voltages.
