Multi-circuit cables, also known as multicables, carry power from power distribution racks and dimmer racks to the lighting instruments, projectors, and other devices. Multicables include break in and break out parts, which attach to the cable and allow power to enter the multicable and to be distributed from the cable.
Some of the multicable parameters that are tedious to manually assign can be automatically assigned, as described in Assigning Circuit Information and Assigning Run ID Information.
Multicable break outs have special labels; entering some of the multicable and break out information can be accomplished from the Object Info palette of the associated label. See Placing Break Out Labels.
To insert a multicable:
Click the Multicable tool from the Spotlight tool set.
Click a polyline drawing mode from the Tool bar. For more information on the polyline drawing modes, see Creating Polylines.
Click to place the start of the cable, and draw the cable polyline, clicking at each vertex. Double-click to finish drawing the cable.
The first time you use the tool in a file, a properties dialog box opens. Set the default properties, and click OK.
After placement, the cable path can be adjusted with the Reshape tool. The properties can be edited from the Object Info palette.

Select the type of multicable |
Cable Path Length |
Displays the total length of cable required for the cable run; the label displays how much extra (unused) cable is present |
Total Vertical Distance |
If the cable needs to travel vertically (to go around an opening, for example), the vertical distance is set for each part. This parameter displays the total vertical distance required. |
Calculate Parts |
Automatically determines the parts, or segments, of cable lengths needed to make up the cable run, using the fewest possible number of connections. The drawn cable is divided into parts, up to a total of nine parts, according to the available cable lengths in stock; each part displays with its own data. |

Specifies the cable voltage provided by the power source; this value is used in the voltage drop calculation. Select Other if the provided voltage is not listed. When Other is selected for the Voltage, specify the power source voltage |
Wire Gauge |
Select the cable wire size |
Voltage Data |
Displays the voltage drop calculations and data. ● Voltage Drop Formula: displays the formula used to calculate the voltage drop. ● Voltage Delivered: displays the voltage delivered at the end of the cable (after accounting for the voltage drop). ● Voltage Drop: displays the amount of voltage lost to cable resistance. ● Percentage Drop: displays the percentage of voltage lost from the cable run. ● CM Value: displays the Circular Mill (CM) value assigned to the cable based on the wire gauge. If the voltage data are not displayed, select Show Voltage Drop Calculation from the Object Info palette. |
Inventory ID |
Enter an optional inventory code for the cable |
User Field __ |
Adds optional notes or comments about the cable, useful for reporting purposes. Field 3 is for entering a number only. |
Display on Drawing |
Enables the display of cable information on the drawing
|
Mark Connections |
Displays a marker and the cable length information where a cable connection is located; the multi head symbol may obscure the connection marker, but the multi head symbol location can be adjusted
|
Display Multi Head |
Adds a symbol at the end of the cable, to represent the break out connectors. Select the symbol to display from the Multi Head Symbol list. Adjust the location of the symbol by moving its control point; restore the symbol to its default position, and prevent it from being moved, by selecting Lock Multi Head Symbol to Standard Position.
|
Lock Labels to Standard Position |
Restores text labels to their default positions, and prevents them from being moved |
