How to wire the incoming line to the primary distribution box
Welcome to our channel @Electricalgenius In this video, we'll take you through a detailed step-by-step guide on wiring a home distribution DB (Distribution Board) box. Single Phase wiring installation is the most common wiring in residential buildings. In Single Phase supply (230V in UK, EU and 120V & 240V in the US & Canada), there are two (one is Line (aka Phase, Hot or Live) and the other one is Neutral) incoming cables from the utility poles to the kWh energy. Distribution board is a safe system designed for house or building that included protective devices, isolator switches, circuit breaker and fuses to safely connect the cables and wires to the sub circuits and final sub circuits including their associated Live (Phase) Neutral and Earth conductors. A distribution board or distribution box is where the main power supply is distributed to multiple loads. At the heart of the panel is the main breaker, a large switch that controls power to the entire system and provides overcurrent protection for all branch circuits.

What is the square millimeter size of the incoming line to the distribution box
For distribution boxes that handle only lighting circuits or small power loads, if the incoming wire size is less than 10 square millimeters and the number of circuit switches is fewer than 20, the width of the box should be calculated by summing the width of the switches and adding. For distribution boxes that handle only lighting circuits or small power loads, if the incoming wire size is less than 10 square millimeters and the number of circuit switches is fewer than 20, the width of the box should be calculated by summing the width of the switches and adding. The maximum length of absorption lines used in conjunction with the gravity distribution shall be 60 feet. (i) For accessibility, it is necessary that the distribution box be located and have a removable cover not more than 12 inches below grade. Lug pad dimensions are included for main incoming line compartments. Front-access switchboards align at the rear.
