7 APPENDIX Ⅲ Ⅲ Ⅲ Ⅲ 24V AC Cable Diameter and Transmission
Distance Relationship

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.
