The wiring in the distribution box has a joint

‌Wiring Direction‌: Wiring between the main circuit breaker and each branch circuit breaker in the box generally goes on the left, and the wiring out of the distribution box generally goes on the right. Choosing the right junction box: Select the junction box according to the environmental conditions, for example, surface-mounted for damp environments or flush-mounted for. ‌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 junction box handles connections and wiring for multiple circuits, making it perfect for places where you need easy access for future changes or repairs. A joint box simply joins wires together, usually in a more permanent setup. It is a secure and organized way to manage the complex network of connections and ensure the safety and efficiency of the system.
