APPENDIX C
24 Vac Wire Gauge and Transmission Distance
The following table shows the recommended maximum distance adopted for the different wire sizes when the 24 Vac voltage loss 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 80 VA which is installed 35 feet (10 m) from the transformer, the minimum wire gauge required is 0.8000 mm.
