24V AC Wire Diameter and Transmission Distance Chart
:
The transmission distance listed below are farthest ones recommended for each given wire diameter when the 24V AC 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 as 80VA, installed 35 feet (10m) away from transformer, needs a wire with a minimum diameter of 0.8000mm.
