The electrical distribution box at the construction site lacks a grounding wire
148 (Grounding Conductor): Requires metallic junction boxes—and by extension, cabinet doors—to bond to ground using a designated grounding screw or clip. When properly done, current from a short or from lightning follows this path, thus preventing the buildup of voltages that would. California's 2025 electrical code sets clear grounding and bonding rules for service equipment, solar systems, pools, and more. California's grounding requirements come from the 2025 California Electrical Code (CEC), which took effect January 1, 2026, and applies to all new electrical installations. The EGFCP helps operate devices such as circuit breakers and fuses or ground-fault detectors in ungrounded systems. Why is it so important to ensure you have proper grounding and bonding for your electrical system? First and foremost is the safety of personnel within a building. We'll blend insights from field experiences and code requirements to give you clarity you can actually apply—no technical jargon fluff. Which circuit conductor must be grounded.
