Appendix 3 24VAC Wire Gauge & Transmission Distance 

The following table describes the recommended max. distance adopted for the certain wire gauge 
when the loss rate  of  24VAC voltage  is less than 10%. For the AC driven device, the maximum 
allowable voltage loss rate 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 0.8000mm is required as 
the minimum wire gauge.
