Figure 4-1 and Figure 4-2 show how length is determined for out and back tap T-Tap 
style wiring.

Figure 4-1  Calculating wire run length for a simple out and back

When using T-taps, the total length of all taps and the main bus must not exceed 
40,000 feet. This requirement must be met in addition to the maximum distance 
requirements for the various wire gauges.
