2200 W DC Power Distribution Box

2200 W DC Power Distribution Box

Figure 5-11 shows a 2200 W DC power distribution box.

Figure 5-11 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 5-12 shows a -48 V two-way short-circuiting bar.
