What are the grounding requirements for the concealed door electrical distribution box
148 (Grounding Conductor): Requires metallic junction boxes—and by extension, cabinet doors—to bond to ground using a designated grounding screw or clip. Why ground the door if the cabinet body's already grounded? Imagine this scenario: You're racing to finish wiring up a production line. Then your supervisor walks by and points at the ungrounded door— "Add a wire to that!" Ugh. In electrical installations, grounding (also referred to as earthing) is a critical aspect that ensures the safety and functionality of equipment while preventing electrical hazards. Proper grounding protects both the equipment and personnel from electrical faults, such as current leaks or surges. During fault conditions, low impedance results in high fault current flow, causing overcurrent protective. What is the goal of the NEC requirements for grounding and bonding? Section 250.
