New features

Custom IEC ampacity values for large cables 400-1000 mm²

IEC cable sizing now lets you enter your own current-carrying capacity (ampacity) values for cables of 400 mm² and larger. Before, these sizes were checked on voltage drop alone, because IEC 60364-5-52 has no tables for them. Now you can enter the values from your cable datasheet, so large cables get a full ampacity check.

How does it work? 

The Installation parameters tab now includes a table for entering ampacity values for each cable configuration, covering cable sizes from 400 to 1000 mm². These values are saved in the DWG and used in cable sizing calculations. A warning appears if a required cable size has no value entered. An info icon in the results identifies cable sizes calculated using your values. If no ampacity is provided in the table, the cable size is still determined based on voltage drop, as before.

Improvements

Labeling styles applied when re-labeling

Re-labeling an area that already has labels applies the style settings from the Labeling window along with the text. Before, re-labeling updated only the label text. To change the style, you had to delete the labels and label again, which could shift their positions. Now, you can change the styling in the Labeling window and re-label to update existing labels, without deleting and recreating them. 

How does it work?

When you re-label, the style you set in the Labeling window applies to existing labels, while any style changes you made by hand are kept. This applies to newly generated labels. 

Minor updates

• The maximum “Torque Tube bottom gap, m” value is raised from 0.5 m to 5 m, so you can now represent trackers with a higher torque tube.
• The maximum gap between frames for East-West systems is raised to 10 m, so you can leave room for access roads or obstacles without splitting your layout into separate areas.
