Appendix II

Wire Diameter & Transmission

Distance Comparison Chart

The transmission distance listed below is the farthest recommended for each given

wire diameter when the 24Vac voltage loss ratio is below 10% (for equipment
powered by AC, the allowed maximum voltage loss ratio is 10%). For example, a
set of equipment with nominal power of 80VA, installed 35 feet (10m) away from
transformer, needs a wire with a minimum diameter of 0.8000mm.
