The following chart can be used as a guideline to determine the necessary wire gauge and maximum cable distance for 24VAC applications where 2-conductor wire is used to power equipment such as enclosures with 24VAC accessories (heater, blower, etc.), or other equipment using low voltage input.
(Do not use this chart to determine wire runs for pan/tilts;conductor requirements and cable distances must be determined by the manufacturers specifications.)
Distances are calculated in feet.
