Type A receptacles accept class II ungrounded plugs that have two flat parallel prongs that are standard in most of Central and North America. The technical name for the Type A receptacle is ungrounded NEMA 1-15. Plugs are only inserted into a Type A plug in a particular manner because the neutral blade is wider than the live blade. Type A receptacles use 120 volts.

Type B electrical outlets use 120 volts. The American grounded NEMA 5-15 three-pin plug has been in use since the 1970s. The plug has two flat parallel pins and a round, longer grounding pin. Like the Type A receptacle, the neutral pin on a Type B outlet is larger for correct positioning.

The Type C receptacle uses 230 volts, and its technical name is CEE7/16. The receptacle’s plug is ungrounded and has two round prongs. The receptacle is generally popular in class II applications with demands of less than 2.5 amps.

The Type I plug has two flat 1.6-mm thick blades that form an upside-down V. The flat grounding pin is longer than the other blades.
