3.
If thin cable trunk line is used for a section, then refer to
and

If the electric current in both thick trunk line and thin trunk line are lower than
the values provided in the respective tables (
), then the
network can support a single supply center-connected configuration.
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.
electric current limit for 400 ft (Section 1) = 2.63 A.
electric current limit for 400 ft (Section 2) = 2.63 A.
Conclusion
: Power supply located in the center is feasible for both sections.
