NOTE: Distances are calculated in feet; values in parentheses are meters.

For example, an enclosure that requires 30 VA and is installed 94 ft (28 m) from the transformer would require a minimum wire gauge of 20 AWG.

Models with heaters require 24 VAC for the heater; the heater uses 58 VA. If the camera uses 24 VAC, add the camera power to that of the heater and refer to Table B to determine the size of wire to use.
