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