Magnitude’s Voltage Drop Calculator for low voltage lighting runs. By using wire AWG it allows you to receive the voltage losses over long runs. The default limit for the voltage loss is 10.5V DC on the 12 V DC line and 21 V DC limit on 24V DC line.
You may modify the limit according to your needs in the voltage window.
