Does the jumper wire in the distribution box need to be grounded
The distribution cabinet needs to be grounded. Grounding is to ensure the safe and reliable operation of electrical equipment, and to avoid safety accidents caused by electrical faults. The neutral conductor is typically the grounded conductor connected to the system's neutral point, carrying current under normal operation. For a grounded system, an unspliced main bonding jumper must connect.
