APPENDIX Ⅲ THE RELATIONSHIP BETWEEN THE 24V
AC CABLE DIAMETER AND THE TRANSMISSION
DISTANCE
It is the recommended transmission distance when the cable diameter is fixed and the 24V AC
power consumption is below 10%. For the AC device, the max permission voltage power
consumption is 10%. For example, when a device of rated power 20W installed from the
transformer 141 inches (42m), then the min cable diameter is 0.8000mm.
