Single-Phase Connection to Three-Phase
For single-phase items that are connected to a three-phase bus, you can select from AN, BN, CN, AB, BC, or CA (where A, B, and C represent the phase, and N represents neutral). EasyPower automatically adjusts the calculations and base kV based on your selection. When you change phases on a phase connection, EasyPower attempts to match the phase on connected items and warns you if there are any issues.

Note: Your phase descriptions may be different than described here if they have been customized in Tools > Options > Terminology.
The first time you connect single-phase equipment to a three-phase bus, a phase connector symbol is displayed at the connection point. The phase connector appears as two diagonal slash marks below the connection point. .
