Suppose you have a PDB SLD with three buses that have the following arrangement:
-
Bus A has two incomers (CKT-I1 and CKT-I2) and 8 feeder circuits (CKT-1A to CKT-8A).
-
Bus B has an incomer (CKT-I3), 4 feeder circuits (CKT-1B to CKT-4B), and a coupler circuit, CKT-5B (C).
-
Bus C has two incomers (CKT-I4 and CKT-I5), 4 feeder circuits (CKT-2C to CKT-5C), and a bus riser circuit, CKT-1C (R).
-
The bus riser-coupler pair connects buses B and C.
The diagram appears as follows when there are no bus breaks, with illegible labels:
The drawings below show how different parts of the SLD appear when you select to force bus breaks and specify a maximum of three feeder circuits to display per bus section.
Breaks on Bus A
The first bus break appears after the third feeder circuit. The final bus section contains the last two feeders. Note that both of the incomer circuits appear on the first bus section only.
Breaks on Buses B and C
The first break on Bus B appears after the third feeder circuit; the second section does not break after the coupler, even though it is the third circuit on that section; instead, the coupler-riser pair is displayed on the same row, and the software forces a break after the third circuit on Bus C.
