It is also common for the120 V distribution in commercial spaces and office spaces of industrial facilities. Three-phase 120/208 Y is much less common but common for multi-unit residential buildings in some areas. It is also used somewhat in commercial buildings. Hi leg wye appears to be very rare and never used for residential units. Where is is used, the 208 volt connection is generally prevented from being used. | |
