EXAMPLE: An enclosure that re-
quires 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.

The following are the recommended maximum distances for 24 VAC applications
and are calculated with a 10-percent voltage drop. (Ten percent is generally the
maximum allowable voltage drop for AC-powered devices.)
