NEMA 6 refers to a type of electrical connector and plug configuration defined by the National Electrical Manufacturers Association. It is commonly used for 240-volt applications, such as in electric dryers and some power tools. The NEMA 6 connector is designed to handle higher amperage, typically rated for 30 amps, making it suitable for heavy-duty electrical devices. The NEMA 6 plug features a specific arrangement of prongs that ensures proper alignment and prevents accidental disconnection. It is available in various configurations, including NEMA 6-15 and NEMA 6-30, which differ in their amperage ratings and physical design. This standardization helps ensure safety and compatibility in electrical installations.
