Insert and configure a circuit

Use Circuit Builder to insert and configure a 3-phase motor circuit.

You now construct a new motor circuit on the extended 3-phase bus.

Insert and configure the circuit

1. Click Schematic tab Insert Components panel Circuit Builder drop-down Circuit Builder. Find
2. The Circuit Selection dialog box displays.
   
3. Expand 3ph Motor Circuit.
4. Select Horizontal - FVNR - non reversing.
5. Change the Rung Spacing: Horizontal to 0.5.
6. Select Configure.
7. Specify insertion point at rung 217.
   

Circuit Configuration

A circuit is made up of individual circuit elements and the wiring that connects them. Circuit Builder inserts a template drawing. This template contains the base wiring for the circuit and strategically positioned “marker blocks”.

The “marker blocks” control what circuit elements are presented in the Circuit Configuration dialog box. For example, a “marker block” indicates the need for a Disconnecting Means in the circuit. Various options for the Disconnecting Means are presented in the dialog box. The option selected for this circuit element is inserted at the location of the “marker block”. Circuit Builder dynamically builds the complete circuit based on the selections you make on this dialog box.
