（重定向自Duplex receptacle）

Common 125-volt receptacles in general use throughout North America. All accept a 1-15P plug, and the two on the left accept a 5-15P plug. The NEMA 5-15R device on the far left is most common.

NEMA 5-15P plug and NEMA 5-15R receptacle (different scales, blade spacing is 0.5 inches (12.7 mm) for both.) Each receptacle also accepts an ungrounded plug, whether polarized or unpolarized.

NEMA receptacles, with their common US uses listed

NEMA connectors are power plugs and receptacles used for AC mains electricity in North America and other countries that use the standards set by the US National Electrical Manufacturers Association. NEMA wiring devices are made in current ratings from 15 to 60 amperes (A), with voltage ratings from 125 to 600 volts (V). Different combinations of contact blade widths, shapes, orientation, and dimensions create non-interchangeable connectors that are unique for each combination of voltage, electric current carrying capacity, and grounding system.
