Wire Gauge
Maximum distance from transformer to load
Table A. 24 VAC Wiring Distances
The following are the recommended maximum distances for 24 VAC applications
and are calculated with a 10-percent voltage drop. (10-percent is generally the maxi-
mum allowable voltage drop for AC-powered devices.)

Total vA consumed
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.
