Appendix
24VAC Wire Diameter and Transmission Distance
Comparison Chart
When the line diameter size is certain, when the 24VAC voltage attrition rate is lower than 1 0%, the
recommendation maximum transmitting range. (Talking of the exchange power supply's equipment, the
biggest permission voltage attrition rate is 1 0%. For example: An equipment rated power is 80VA, the
Installed Min diameter size which is 35 feet away from the transformer (10m) needs is 0.8000mm .
