How to do the wiring work inside the distribution box

11. The reserved position is usually placed on the right side of the distribution box. A complete position is reserved between the first row of main circuit breakers and sub-circuits for wiring the first row of circuit breakers.

12. The wiring between the main circuit breaker and each sub-circuit breaker in the Power distribution cabinet box is usually on the left, and the outlet wires of the distribution box are usually on the right.

13. When installing the circuit breaker, first pay attention to the position of the circuit breaker installation hole on the box cover to ensure that the circuit breaker position is in the reserved position of the box cover.

14. The neutral wire between different phases shall not be shared. For example, if the first yellow wire from phase a is connected to two 16a lighting circuit breakers, then the neutral wire of the circuit breaker matched by phase a can only be matched with these two circuit breakers, and directly connected to the neutral wire terminal after matching.
