What route separation means here
This planner handles a routing-organization problem: multiple cable groups must be assigned to distinct tray zones while considering separation classes and a simplified capacity limit. It does not claim that the entered classes represent a universal code requirement.
How the allocation works
Each cable group receives a separation-class label and a planning size. Groups are then allocated to the least-loaded eligible zone. Groups with the same class can share a zone, while groups with different classes are kept apart whenever another available zone exists.
Why separation class is configurable
Projects may define cable groups around power, control, instrumentation, communications or other categories. Actual separation requirements depend on the project, cable system and applicable rules, so the planner avoids inventing fixed distances.
Worked example
Suppose five groups have classes POWER, CONTROL, POWER, SIGNAL and CONTROL. With three zones, the planner attempts to place similar classes together and preserve capacity, producing a practical preliminary routing allocation.
Capacity interpretation
The planning size is an abstract entered quantity rather than a fabricated tray-fill calculation. It can represent whatever consistent size metric your planning workflow uses.
Limitations and safety
Verify actual segregation requirements, cable compatibility, tray fill, shielding, electromagnetic compatibility, fire requirements and project-specific routing rules before installation.
Frequently asked questions
Does this determine legally required separation distances?
No. Separation class and capacity are user-defined planning inputs.
Can different cable classes share a tray zone?
The planner may allocate them only when no better separated zone is available, but final suitability must be verified separately.
Is planning size the same as cable diameter?
It can be used as a consistent planning measure, but the tool does not convert it automatically to cable-fill area.
