   Hello, and at my place of employment we have devices such as UPSs and   
   test equipment that require a 208 VAC 50A single-phase service.  These   
   circuits are gotten from a breaker panel that has an incoming 120/208   
   VAC 3-phase, 4-wire service.  The single phase 208V service is most   
   often terminated in a wall-mounted receptacle that is physically a   
   larger version of the standard u-ground 120 VAC 15A receptacle.  Sincerely,
