Definition of Standard U.S. Outlet

An electric outlet that can accept an ungrounded type A or grounded type B plug.

Ungrounded type A plugs typically have two flat prongs and are generally polarized while grounded type B plugs have two flat prongs and a rounded grounding plug.

A polarized plug can only be inserted into an outlet one way since it’s usually made of two differently-sized prongs—the large one is the neutral line and the small one is the hot line.

Additionally, a standard U.S. outlet supplies about 120 volts.
