If the electric current determined in Step 2 in a given section exceeds the maximum
electric current capability according to the respective tables, then based on the
circumstances, execute one of the following:
If the electric current exceeds the maximum,
a. In one of the two sections, then execute one of the following actions:
– Move the position of the supply along the overloaded section and
recalculate.
– Move the power supply to push one of the nodes from the overloaded
section to the other section.
b. In both sections
– use two power supplies.
Figure 25 shows an example of a single supply center-connected network, which
uses a thick cable trunk line with a overload.
Calculation method:
Section 1 = Section 2 = 400 ft.
Section 1 electric current = 1.1 A +1.25 A + 0.5 A = 2.85 A.
