    An ordinary household electrical plug in the United States. Characterized by having two flat blades and a semi-round ground pin. A plug rated at 20 amps will have one blade perpendicular to the other, where a standard 15 amp plug has the two blades in parallel with each other. Some are also polarized so the neutral blade is larger than the hot blade, so when there is no ground pin the plug can’t be inserted backward. outlet
