Metal distribution boxes must be grounded to prevent electrical hazards. According to NEC standards, metallic boxes and cabinet doors require bonding to a grounding conductor using dedicated screws or clips, ensuring that any stray electricity is safely directed to ground . Non-metallic boxes, such as PVC or composite enclosures, generally do not require grounding unless they include metallic frames or components . In industrial and commercial applications, each distribution box and controller is typically grounded using specified wire sizes (e.g., 10 AWG in the US or 6 mm² elsewhere), with connections to a central grounding point to maintain low resistance (<0.1 Ohm) across the system . Proper grounding ensures safety and compliance with electrical codes, protecting both equipment and personnel. Older installations or DIY setups may have ungrounded boxes due to outdated wiring or improper installation, which poses a safety risk and should be corrected .
