Tipload module and database data
When using a pole from the Poles database in the tipload module, the module can calculate the percentage loading of that pole based on settings for Load Combinations.
For this loading, for example, the Ultimate limit column data (selected at Pole Strength class) will be used when performing that calculation.
If you were using the pole circled in red the value 21 would be used as the pole capacity, being the value in the Ultimate strength column for that record.
This value is multiplied by the Strength Reduction Factor, 0.7 in the example above (this SRF can be manually edited in the Tipload module).
