2-4 Wire and Cables Installation Manual
Table 2.2 Wire Gauge Table - For common system devices
The following table indicates the recommended minimum wire gauge for a given length of cable. This table reflects
the fact that there are two conductors, power and ground, running to each device.
Note: 1000 feet of cable means the supply current travels a total of 2000 feet.
