A power cord is an electrical cable used to connect an appliance to a mains electricity supply. It consists of a flexible cable that is connected to a plug at one end and a male connector at the other. In some cases, it may include other attachments such as a retaining clamp or a shield over the power conductors. The cord can be fixed to the appliance or dragged hundreds of feet to reach an outlet.

The best power cord for you will depend on your specific needs. For instance, if you have a computer, you will need a cord with a standardized IEC 60320 C13 or C14 appliance connector. Likewise, if you have a television, you will need a cable that is compatible with your country's receptacles. However, there are also special types of cables for sensitive equipment, such as heating appliances. There are also cord sets that contain both male and female connectors molded onto the flexible cord.

Another consideration is the number of fuses installed in a power cord. These fuses protect your device from overcurrent or overheating. Fuse ratings are determined according to the appliance's wattage and the size of the cable. If you have a high-wattage appliance, a 3A fuse is recommended. On the other hand, if you have a low-wattage appliance, a 13A fuse is probably enough.

A detachable power cord is also useful. This makes it easier to replace a damaged cable and simplifies the factory test process. Also, this type of cord is very low-cost. Some power cords may come with a pilot light that indicates voltage. Depending on the manufacturer, you can even find cords that have a leakage current detector.

A power cord with a fuse may look intimidating, but you can rest easy. Most power cords with a fuse are rated for a minimum of 5 Amps, and can go up to 15 Amps. They can also be custom-made to match your needs. One example is a 12-foot master power cord with a 15-amp fuse, heavy battery terminals and an inline 15-amp fuse holder.
