Table C describes the recommended maximum distances for 24 VAC applications, which are calculated with a 10 percent voltage drop. (Ten percent is generally the maximum allowable voltage drop for
For example, an enclosure that requires 30 VA and is installed 94 feet (28 m) from the transformer would require a minimum wire gauge of 20 AWG.
