3. If thin cable trunk line is used for a section, then refer to Table 23 and Figure 9.
4. If the electric current in both thick trunk line and thin trunk line are lower than
the values provided in the respective tables (Table 13 and Table 23), then the
network can support a single supply center-connected configuration.
Figure 24 shows the single supply center-connected using a thick cable trunk line.
Calculation method:
Section 1 length = Section 2 length = 400 ft.
Section 1 electric current = 0.1 A + 0.25 A + 0.2 A = 0.55 A.
Section 2 electric current = 0.15 A + 0.25 A + 0.15 A = 0.55 A.
Table 13 electric current limit for 400 ft (Section 1) = 2.63 A.
Table 13 electric current limit for 400 ft (Section 2) = 2.63 A.
Conclusion: Power supply located in the center is feasible for both sections.
