If you own a computer, you’re likely to need a power cord. Also known as a mains cable, this type of cord is the primary source of power for a computer, as well as a peripheral device. A power cord comes in many different lengths and configurations, depending on your specific needs. To keep your home or office computer in top shape, you should buy one that matches your current needs. Read on to learn how to choose the right power cord for your needs.
Before you buy a power cord, be sure to check its electrical ratings. Different models have different ratings. Generally, a cord with an S grade is 600 volts, while a cord with an SJ grade is 300 volts. Other common types of cords are T grade, P grade, and O grade, with each grade describing its characteristics. Some cords are oil resistant and have two “O”s on them, meaning they are rated for a specific voltage.
The power cord may come with a retaining clamp to keep the connector in place and prevent accidental yanking. Detachable leads may also have twist-locking features or other attachments. Cord sets may also come with additional accessories, such as fuses for overcurrent protection, a pilot lamp to indicate voltage, and a leakage current detector. Some cords are designed to carry electricity hundreds of feet away from an outlet, so be sure l14-30 to choose one that fits your needs.
Another benefit of retractile cords is that they save space. In areas where many electronic devices are used, space can be at a premium. Retractile cords take up the least amount of space when not in use. They also eliminate tangles and safety hazards associated with tangled cables. Retractable cords can be expanded and collapsed again quickly – making them an excellent choice for short-distance applications.
Manufacturers must understand global electrical standards before designing a power cord. While there are no universal standards, certain products are required to comply with the regulations of various countries. In North America, UL 62/CSA C22-2 No 49-14, whereas in Europe, EN 60779 requires cables to meet certain criteria. If a cord doesn’t meet one of these standards, it must have a HAR mark. For example, a H03VV-F cord is fine wire and is suitable for use in areas where there are different voltage and frequencies.
The NEMA 5-15P plug has three prongs and comes with a variety of connectors. It is important to match the plug with the specific use for which it is designed. For example, a NEMA 5-15P cord should have a side-facing plug or a wall-mounted plug. Some power cords have multiple outlets, and have a neutral, hot, and ground wire. This cord is suitable for use in medical facilities because it has a higher quality than a non-hospital-grade cord.
NEMA 5-15P cords are the most common. They feature three-wire circuits and are designed for 15 A at 250 V. An NEMA 5-15P power cord is a common type, but you can find NEMA 5-15P power cords with other types, too. The type of plug you purchase should also be compatible with the type of receptacles you own. The same goes for the NEMA 5-15R.
