The transmission distances listed below are farthest ones recommended for each giving

wire d iameter when the 24 VAC v oltage loss ratio is below 10%(for equipment powered by

AC, the allowed maximum voltage loss ratio is 10%).For example, 5 sets of indoor equipment

with n ominal power as 12 VA and 2sets outdoor equipment with nominal power as 50 VA,

install 28 feet (8m) away from transformer, need total power of 160VA(5

12VA 2

50VA),

need a wire with a minimum diameter of 1.0mm.
