The voltage drop information box shows the calculated value, and the border is traffic light coloured to indicate if the cable is adequate.
The CSA and maximum allowable voltage drop can be set.
When determining the correct cable size for a required voltage drop, it is advisable not to decrease the CSA of the cable. Reducing the CSA may reduce the current rating to unacceptable limits. The design current and cable rating are shown in the information box, to help the user avoid this situation.
