The second identifier, which is a number, assigns the voltage rating; for example, a “5” represents a voltage rating of 125 Vac and a “6” denotes a rating of 250 Vac. The rating given is the highest voltage allowed for the device. Please refer to the accompanying chart to see other voltage ratings.
13 Σεπ 2023 · Readers with specific questions should refer to the applicable standards or consult with an attorney. These charts show many of the possible NEMA configurations for different amperages and voltages, from the common wall socket to more rarely seen plugs and receptacles.
Other electrical configurations use the ANSI/NEMA WD 6 standard. Such standards apply to the higher voltage, 3 phase applications, and they typically serve specific uses like ship-to-shore connections. Distinguishing The Connectors, Plugs, and Receptacles.
G. W. ANSI/NEMA WD 6-1997. NEMA CONFIGURATIONS FOR LOCKING PLUGS AND RECEPTACLES. 15 AMPERE. 20 AMPERE. 30 AMPERE. 50 AMPERE.
North American Non-locking NEMA Configurations. Use this chart to determine which general purpose NEMA plug or receptacle is needed for specific applications. Information obtained from ANSI/NEMA WD-6 standard. Face and pin sizes not necessarily to scale.
All NEMA 5 devices are three-wire grounding devices (hot–neutral–ground) rated for 125 V maximum, with the 5-15, 5-20 and 5-30 being grounded versions of the 1-15, 1-20 and 1-30, respectively.
Understand NEMA plug and receptacle configurations. Selecting the appropriate equipment for your needs is essential for safety and functionality.
