Standard for incoming line of circuit breaker in 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. In a distribution box, the way circuit breakers, busbars, neutral conductors, and grounding...
