     North American standard plug (no grounding)                                                                  


Electrical parameters:

Current: 15A Voltage: 120V Frequency: 60Hz


North American standard plugs are manufactured to NEMA 1-15, 5-15, 5-20, 6-15, 6-20P plug standards. In the United States, these American standard two flat line plugs are subject to NEMA (American Electrical Manufacturers Association) management and UL certification. The plug and socket standard in Canada is CSA C22.2-No. 42. Plugs that meet NEMA 5-15P output styles are also used in countries in Mexico, Japan, Korea, Taiwan, Central America, Colombia, Venezuela, Ecuador and South America's West Coast region. Power systems in developing countries are usually not grounded. The socket network is not recommended to cut off the grounding pin and eliminate safety grounding. It is not safe. However, the remediation of the grounding wire may be provided. The electrical parameter of the North American plug is 2.5A-15A/125VAC.

UL-certified and CSA-certified plugs. It can be used in various sizes and types of cables, mainly for data transmission, such as power supply servers, computer data storage systems, network equipment, and industrial equipment. Standard 15A/125VAC plugs are the most popular, with low currents of 20A/250VAC. U.S. standard injection molding power cords and plugs are used in medical facilities and are easy to install. There are dedicated medical grade plug systems. On one side of the wire is the rated current of 10A IEC-60320 connector. 15A/125VAC maximum output rating.

The device manufacturer requires that the device's power cord is controlled by UL and CSA standards. In order to harmonize the changes with the IEC standards and the UL amendments to the information technology equipment standards. UL certification (60950 and CAN/CSA C22.2 number 60950) and medical equipment standards (UL certification 60601 and CAN/CSA C22.2 number 60601), UL certification 60950 and CAN/CSA C22.2-60950 joint declaration, power cord The ground wire must be a two-color line, green and yellow.

UL Listed 60601 and CAN / CSA C22.2 No. 60601 require that the grounding be green/yellow, the neutral line light blue, and the live line brown. There are indications that UL and CSA may not rigidly enforce these requirements. In both cases, it is recommended to use color-coded cables with polarity-recognition colors (brown, blue, green/yellow), and UL and CSA certification requirements are accepted. Prior to this, some equipment manufacturers were able to distinguish between North American power cord polarity color coding, namely black, white, green, and international standard universal color coding, namely red, blue, green/yellow. UL and CSA certification now require equipment manufacturers to unify the identification of standard power cords (Firewire - Brown, Neutral - Blue, Ground - Green/Yellow).
