4.7 Cable Type Catalog Data
Cable type data is critical of tray and conduit sizing. The cable OD is always used for tray sizing.
The override cable area is only used for conduits. Since separate ground conductors are not run
in tray but are run in conduit, you should input an override cable area when the ‘Ground
Conductor’ value is ‘Y” (meaning a separate ground is included with the cable). Please note that
number of conductors are for one cable jacket. Take care that the all conductor sizes have been
input to the pull downs in the project data table. If the number of conductors (per cable jacket) is
greater than ‘1’, CableMatic uses traysizing rules for multi-conductor cables.
The last field is “Number of Current Carrying Conductors”. This value is for the entire cable. If
you leave this value blank, CableMatic assumes the value to be the product of the Number if
Cable Jackets and Number of Conductors per Cable Jacket. This data is used to restrict cables
in conduits and is related to data that is entered in the Service Levels table. This value is used
during cable routing and when reporting conduit fill.
In addition the number of conductors plus the ‘Chart Name’ provides data for preparing
termination data.
Permissible segregation codes do not affect cable routing. However CableMatic provides a
check to identify cables that use a cable type that does not have a corresponding segregation
code.
