In power distribution systems, the rated voltage parameter of the terminal power distribution block indicates the maximum voltage level it is designed to withstand. A distribution box is a low-voltage electrical enclosure that receives incoming power and distributes it safely to multiple outgoing circuits through protective and switching devices such as MCBs, RCDs, RCBOs, fuses, isolators, busbars, neutral bars, earth bars, and surge protective devices. The. Voltage, measured in volts (V), represents the electrical potential difference between two points in a circuit. It's the “pressure” that pushes electrical current through conductors, similar to how water pressure moves water through pipes. Different voltage values correspond.
