2.3.2  Connection 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. 

Busbar type 

Max. load number   

Note 

Battery -48V busbar 

0~5 

High-priority load busbar 

0~19 

Low-priority load busbar 

0~28 

Total number of the load should not 

exceed 20 with 18mm-width MCB or 

not exceed 28 with 13mm-width MCB. 

 

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:
