Cable directly connected to the live wire bar of the main distribution box
The circuit's neutral wire connects directly to a terminal on the breaker. The breaker then connects internally to the panel's neutral bus bar, often via a factory-installed pigtail wire or a plug-on neutral tab. A distribution board or distribution box is where the main power supply is distributed to multiple loads. Always begin with disconnecting the main supply before accessing any enclosure containing distribution components. This prevents arc faults and ensures safety when modifying or inspecting current paths. In the following tutorial, we will show how to wire 120V single-phase and 240V split-phase circuit breakers and loads inside a residential main panel. The figure below shows a typical breaker panel used for 120V and 240V. 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.
