There are many different kinds of power cords, but you should know which one you need to use. The plugs on laptops and power strips are generally C6 receptacles. Cords that are SJ grade are for 300 volts, and S grade cords are for 600 volts. PVC-coated cords are heat-resistant and durable, and you can also get cords with oil resistance.
The cords come with different wire gauges and voltages, depending on their intended use. In North America, green wires are typically used; in other countries, yellow stripes are common. Depending on where you purchase your cords, make sure to check the voltage rating. Having the right voltage rating on the power cord is essential to ensuring your product functions properly. If you are unsure of what voltage you need, check with the manufacturer’s warranty to ensure it is up to code.
If you’re buying a power cord for a generator, check its ratings. A 15-amp cord can run up to 30 amps. Also check the receptacle label to see which cord is right for your generator. If the 60 amp fuse label says L14-30P, that means it has a twist lock 30 amp plug. Then you’ll know how many amps you’ll need. The longer the cord is, the higher the electrical resistance. Choose a cord with the right wattage and length to minimize this loss of power.
A non-detachable power cord may not be removable, and should be attached to the appliance with a retaining clamp. A detachable lead contains a female connector to minimize the risk of a protruding pin. Other features of power cords include twist-locking capabilities, and other attachments. Cord sets may come with additional accessories like fuses for overcurrent protection, a pilot lamp for voltage indication, and a leakage current detector.
A power cord with a different voltage rating will work in a different way in your country. The IEC 60320 standard defines the voltage rating of power cords. It specifies what the connectors can and cannot handle and also includes the temperature rating. Generally, power cords with a C13 rating can work in countries with varying temperatures. However, if you need high voltage to operate a machine, make sure the power cord is listed as a C14 or higher.
While there are many different types of power cords, the most common ones are NEMA 5-15P and C13. The latter is the most common type in Europe. The CEE 7/7 standards set standards for both plugs and receptacles. You can use Interpower’s Guide to Worldwide Plug Patterns to find out which ones work for your appliances. It is also important to consider the plug’s style, as North American and Japanese Class I cords look the same but are not approved for use in Japan.
When choosing your power cords, make sure to check the plugs for voltage. IEC 60320 power cords use odd numbers for the male appliance inlet and even numbers for the matching female connector. In the US, power cords are often NEMA (National Electrical Manufacturers Association) compliant, which specifies the receptacle and plug configuration for North America. The type A connector has two conducting blades, while Type B has a grounding rod.
