Recommended maximum distances for 24 VAC with 10-percent voltage drop.
(10-percent is generally the maximum allowable voltage drop for AC-powered devices.)
EXAMPLE: An enclosure that requires 80 vA and is installed 35 feet (10 m)
from the transformer would require a minimum wire gauge of 20 Awg.
NOTE: Distances are calculated in feet; values in parentheses are meters.
