Insert a one-line dual power feed circuit

In this part of the exercise, you insert a dual power feed circuit. A dual circuit has two distinct circuits running off the same bus-tap. Each circuit can be independently configured.

1. Click Schematic tabInsert Components panelCircuit Builder drop-downCircuit Builder.
2. The Circuit Selection dialog box displays.
3. Select One-line Power Feed: Vertical - Dual feed.
4. Click Configure.
5. Specify an insertion point on the one-line bus.
   

   The Circuit Configuration dialog box displays. Notice that some circuit elements have a “(2)” prefix. These elements make up the second circuit in the dual circuit.

6. In the Circuit Elements section, select Load Setup.
7. In the Setup & Annotations: Load Setup section, select the Browse button.

   The Select Load dialog box displays.

8. Select Type: Transformer, Voltage (V): 480, and Phase: 3.
9. Select an entry from the grid and click OK.
10. Continue selecting Circuit Elements for the first circuit:

    Load: Generic box

    Disconnecting means: None

    Terminal strip or connector: Square
