Does the distribution box need a copper wire for grounding

The metal box itself should be processed with a "box grounding bolt" (with PE mark), which must be connected to the grounded PE bus with a copper core wire or a special braided soft wire; 3. The correct connection method of Distribution box grounding wire mainly includes the following steps: 1. When grounding fails here, it's like having a spaceship without a heat shield—everything inside becomes vulnerable to surges, faults, and electrical fires. 24 (A) (1) through (4): (1) General. The GEC connection to the neutral conductor at service equipment must be made at any accessible point. The answer to whether you need a ground rod for a sub panel largely depends on the specific circumstances of your installation, as well as local electrical codes. Generally, the National Electrical Code (NEC) provides a framework, but local regulations may impose stricter requirements.
