DC Circuit
The following figures show the DC circuit description for the system. 19" systems have 20 bullet-style
distribution positions per panel. 23" systems have 26 bullet-style distribution positions per panel. The
positions in the initial distribution panel are selectable between either battery inputs or load outputs.
Figure 3 shows the option where all load positions are connected to the system through a low voltage
load disconnect (LVLD). Figure 4 shows the option where the battery positions are all connected to
the system through a low voltage battery disconnect (LVBD). Breaker sizes up to 250A, TPS fuses to
70A and GMT fuses to 12A are available bullet modules for this system. DC Connections are made with
double hole lugs on ¼-20 studs on 5/8" centers. The maximum tongue width for breaker connections
is 0.68".
