There are several types of power cords and sets. These power cords and sets are designed to meet various standards and regulations. Interpower, for example, uses a standard method to measure the current that flows through each cord or set. This method measures the voltage and amperage from the plug or connector face to the end of the cable. The measurement is included in UL 817 and CSA 22.2 no. 21-14. Both of these standards are governed by different laws and regulations in different countries.
There are three main types of power cords. Most commonly, these cords are made to handle AC electrical power. This type of electrical power has a sinusoidal waveform, which is common to most electrical outlets. Other types of power cords, called custom power cords, are made for specific applications and can be used to extend the connection between an electric utility and an appliance. A custom cord will have a socket connection on one end and an electrical plug on the other.
UL and CSA standards govern the construction of these cords. Plugs and receptacles must meet the UL 498 and CSA C22.2 no 42 standards. The conductor size is measured in AWG (American wire gauge) and mm2 (millimeters) in order to avoid any electrical shock. Many cords are also rated according to the voltage and the temperature l1430 in the environment. Some cords can be used outdoors or in hazardous locations.
A good reference for buying power cords is the Interpower Guide to Worldwide Plug Patterns. It can help you determine which plug patterns are needed for your device and where they are located. For example, you can determine whether you’re buying a Japanese-made or a North-American-made cord based on the type of plug and connector. The difference between a Japanese and North American cord is that the former does not have a Japan-approved symbol.
A typical power cord set includes a flexible cord with electrical connectors at both ends, as well as a molded electrical plug and receptacle. The electrical connectors are insulated to prevent electric shock, and the cord itself can vary between two and ten meters. The length of the power cords depends on the standards used for their manufacturing. They can be purchased for as low as $2. However, make sure to read and understand the guidelines provided by your local electrical service provider to ensure that you’re getting the right cord for the job.
The National Electrical Manufacturers Association (NEMA) has established standards for plugs and outlets in the U.S. and Canada. These standards define electrical receptacles and cord voltage capacities, as well as the configuration of plugs and sockets. In North America, you’ll find NEMA Type A and B plugs and NEMA Type C15-P cords. Plugs and sockets are often interchangeable. If you’re traveling outside of North America, NEMA 5-15P and 15R power cords are the most popular.
