How do I choose a MCB for DC?

To ensure proper selection of a suitable MCB for a DC circuit, it is essential to first determine the total current of the circuit. Once the current is determined, the appropriate MCB can be selected accordingly. It is important to note that the current rating of the MCB should not exceed the cable's current carrying capacity. Therefore, it is necessary to carefully match the MCB's current rating with the cable's capacity to avoid any potential hazards or damages.
