Longline Electrical Information

The following table is provided for reference only to assist with choosing an appropriate electrical conductor size for your longline application. 

Minimum voltages and actual draw for your remote equipment should be checked in the manufacturer's documentation. Actual voltage drop can vary with a number of factors such as condition of the wire, temperature, connectors, etc. Therefore, for critical situations the user should calculate voltage drop for their specific scenario. An online voltage drop calculator can be found here.

Custom electrical configurations may be available on request.  Contact us to discuss your specific requirements.

The table below shows estimated output voltage at the bottom of a longline with a nominal input voltage of 28VDC and a draw of 5 amps, representing a solenoid on a remote hook or water bucket.
