It includes blades for both 30 amp and 50 amp wiring (3-pole, 3-wire grounding) and is designed for high-amperage 250V plug applications in industrial and commercial settings. It works with a matching NEMA receptacle – NEMA 10-30R for 30 amp, or NEMA 10-50R for 50 amp configurations.
Please refer to the accompanying chart to see other voltage ratings. The third identifier, also a number, identifies the highest amperage rating allowed for use with the device. Finally, the fourth identifier is a letter that determines whether the device is a plug (“P”) or a receptacle/outlet (“R”).
