8:  In the Select Template dialog box, Select Acad_Electrical.dwt. Click Open.
 

9:  In the Create New Drawing dialog box, click OK.

10:  On the Schematic tab, Insert Wires/Wire Numbers panel, click Insert Ladder.
 

11:  In the Insert Ladder dialog box, for Width, type "9.00"

12:  For Spacing, type "0.75"
 

13:  For Rungs, type "25"

Notice that the ladder length is automatically calculated when you click somewhere else in the dialog box.
 

14:  For 1st Reference, type "100" and then click OK.

15:  Select an insertion point for the ladder at approximately 5.00,20.00 or type "5,20" then press ENTER.

16:  On the Schematic panel, Insert Wires/Wire Numbers tab, click Insert Ladder again.

17:  In the Insert Ladder dialog box, for Width, type "8.00"

18:  For Spacing, type "1.00"

19:  For Rungs, type "15"

20:  Notice the 1st Reference is automatically set to 125, which is the next sequential ladder reference number. Click OK.
 

21:  Select an insertion point at approximately 18.00,20.00 or type "18,20" then press ENTER.

22:  The remaining steps will Edit the Ladders:
> On the Schematic tab, Edit Wires/Wire Numbers panel, click Ladders > Revise Ladder.
 

23:  In the Modify Line Reference Numbers dialog box, change the Rung Count value for ladder 1 to "20"

24:  Change the Rung Count value of ladder 2 to "20"

25:  Change the Reference Number Start value for ladder 2 to "150"

26:  Click OK.
 

27:  On the Schematic tab, Edit Wires/Wire Numbers panel, click Trim Wire.
 

28:  On the first (left) ladder, trim rungs 101 and 103.

29:  On the second (right) ladder, trim rungs 151 and 153.
 

30:  On the Schematic tab, Insert Wires/Wire Numbers panel, click Wire.
 

31:  Add a wire starting on rung 100, about one-quarter of the way from the left bus, and ending on the left vertical bus and 101.

32:  Add a wire starting on rung 100, about three-quarters of the way across and ending on the right vertical bus at 101.
 

33:  Add a wire starting on rung 150, about one-quarter of the way across, running down to rung 151 (click) and moving to the right, approximately three-quarters of the way across (click). Continue running the wire down, selecting the ending location on rung 152.

 

34:  On the Schematic tab, Edit Wires/Wire Numbers panel, Add Rung flyout, click Add Rung.
 

35:  Add ladder rungs at references 103 and 153.
