Appendix 3 24VAC Wire Gauge & Transmission Distance
The following table has described the recommended max. distance adopted for the certain wire
gauge when the 24VAC voltage loss rate is less than 10%. For the AC driven device, the maximum
voltage loss rate allowable is 10%. For example, for a device with the rating power of 80VA which is
installed at a distance of 35 feet (10m) away from the transformer, then the minimum wire gauge
required is 0.8000mm.
