Relational Table of 24VAC Line
Diameter and Transmission Distance
The maximum transmission distance s recommended in the situation that
the line diameter is fixed and 24V AC voltage wastage rate is below 10%. As for
the AC main power supply device, a device with an 80VA rated power is installed
in a place 35 feet away from the transformer, then the required minimum line
widths should be 0.8000mm.
