Note:
1. The specifications are applicable at ambient temperature of 25°C. If the temperature is too high, the CSA of the cable should be
increased.
2. The battery cable should reach at least +90°C heat durability. It is recommended to use double-insulated copper-core flame
retardant cable as battery cable

To prevent the MCB stop working upon over-load, the recommended MCB capacity is 1.5 to 2 times of load peak
capacity.
The CSA of the system earth cable should be consistent with that of the max. power distribution cable and not less
than 35mm
