Does the incoming conduit of the distribution box need to be grounded
Systems operating below 50V aren't required to be grounded or bonded per 250. 30 unless the transformer's primary supply is from a 277V or 480V system or an ungrounded system [250. The neutral conductor is typically the grounded conductor connected to the system's neutral point, carrying current under normal operation. Part V of NEC's Article 250 states the rules for bonding services, communication systems, other enclosures, hazardous (classified) locations, piping systems. To quickly remove dangerous voltage on metal parts from a ground fault, the effective ground-fault current path must have sufficiently low impedance to the source so fault current will quickly rise to a level that will open the circuit overcurrent protection device. Bonding is connecting things together with a conductive path to establish electrical continuity. Both are foundational safety concepts in the NEC, and. In the 2023 NEC®, Section 705.
