Phase wires in the distribution box

Live (L) Wire Connection: In a distribution box setup, the incoming live wire (also known as phase or hot wire, denoted as L or Line) connects to the line terminal of the circuit breaker. This serves as the primary source of electrical energy from the mains supply. ‌Arrangement order‌: The circuit breakers should be arranged from left to right, and the reserved position is generally placed on the right side of the distribution box. ‌Wire color‌: The neutral wire is blue, and the color of the phase wire (A phase is yellow, B phase is green, and C phase is red). A distribution board or distribution box is where the main power supply is distributed to multiple loads. Single Phase Distribution Box generally consists of Double Pole MCBs, Single Pole MCBs, and RCCBs. This guide shows you how to organize circuit breaker wiring properly. 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.
