Wire run lengths
•
Use the following table to estimate the gauge of wire required for the application.
•
Wire length based on 15% voltage drop at 12 or 24V using stranded copper wire.
•
The wire gauge listed is a minimum. The gauge can be increased if desired.
•
Distance = total one way wiring distance between power supply and powered device (includes both power wires).
•
For UL installations, the minimum permissible wire size to be used shall not be less than 22AWG.
