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.
