2.3.2Connection Of Load Cables

Loads are connected to the MCB with suitable capacity to avoid their failure to function in the case of overload. The capacity of the MCBs is recommended to be about 1.5 times of the peak value of the load capacity. The load circuit breakers are shown in Figure 1-7. The circuit breakers can be ABB or CBI circuit breakers.

We take the CBI circuit breakers of 13mm for example to illustrate the load cable connection, as shown in the Figure 2-10.

Explanation: the load MCBs and battery MCBs can be configured flexible according to the actual requirements. Their setting range is shown in the following table.

Table 2-3 Configuration number of load MCBs and battery MCBs

Busbar type	Max. load number	Note
Battery -48V busbar	0~5	Total number of the load should not
		exceed 20 with 18mm-width MCB or
High-priority load busbar	0~19
		not exceed 28 with 13mm-width MCB.
Low-priority load busbar	0~28

Cable connection to MCB: strip the power cable end, crimp-connect the copper core to an H terminal, See Figure 2-4 for the cable mounted with a H terminal. After attaching the H terminal to the cable, insert the cable into the wiring hole of the MCB, then tighten the screw to fix the copper core, as shown in Figure 2-11:
