Electrical cords are an essential part of the electrical system and, in some cases, a necessity. But there are some things to consider when choosing a cord. For one, be sure to select a power cord that is certified according to safety standards. If not, you’ll run the risk of electrical fires. There are a variety of power cords that can meet safety standards. Listed below are some of the most popular types.
A general-purpose power cord is a length of 12 to 18 gauge wire that connects an electrical appliance to a wall outlet. These cords are generally used to extend the cords of power-backed appliances or to repair damaged ones. They have a flat-bladed plug at one end, and a bare wire on the other end that is wired to the appliance or battery. These power cords are rated based on their gauge, which tells you how much current they can deliver.
In addition to power cords, there are detachable leads for different applications. For example, detachable leads are safer to use because they have a female connector to avoid the risk of a live pin protruding. Some cords even have twist-locking features and other attachments to make them more flexible. Some power cord sets contain accessories such as fuses for overcurrent construction string lights protection, a pilot lamp for voltage indication, and a leakage current detector.
Internationally recognized standards for power cords are IEC 60320. These cords meet various standards, including voltage, current, temperature, and the type of connector. They usually have a “C” code standard. The IEC 60320 standard specifies the types of connectors for certain combinations of voltage, current, and temperature. The C13 power cord is a typical example of a standardized cord. A few countries have different standards, but most countries recognize the IEC 60320.
NEMA standards for power cords vary by country. In the US, most cords adhere to the NEMA 5-15P plug/receptacle standard. In Canada and North America, NEMA types A and B are used for electrical receptacles and plugs. NEMA type A and B power cords have two conducting blades and an additional ground rod. They are the most common and widely used power cords for electrical appliances.
Several countries use different plug standards for their electrical equipment. The CEE 7/7 is de facto in many countries, while CENELEC countries use a different plug standard. Countries like Denmark and Ireland do not use CEE plug standards. Malta, Cyprus, and Gibraltar use BS 1363 or the CEI 23-50 standard. There is also a CEE 7/7 to C15 plug standard. If you’re traveling outside of the EU, consider purchasing one of these cords and avoid the hassle of figuring out which plugs to use.
