2200 W DC Power Distribution Box
Figure 4-7 shows a 2200 W DC power distribution box.
A 2200 W DC power distribution box can use -48 V two-way short-circuiting bars, each of which provides JG input terminals. A -48 V two-way short-circuiting bar allows a maximum of 120 A input current and converts one input into two outputs to circuit breakers. Figure 4-8 shows a -48 V two-way short-circuiting bar.
A 2200 W DC power distribution box provides short-circuit protection and overload protection.
Table 4-11 lists specifications of a 2200 W DC power distribution box.
