When circuit conductors are spliced within an outlet box, what grounding conductors should be connected?

• A. Only the main grounding conductor
• B. Any and all EGCs associated with any branch circuits
• C. Only the grounding conductor connected to the outlet
• D. No grounding conductors are necessary

Answer: (B)

When splicing circuit conductors within an outlet box, it is important to connect any and all Equipment Grounding Conductors (EGCs) associated with the branch circuits involved. This ensures that all conductive pathways that might carry fault current are properly grounded. By connecting every EGC linked to the branch circuits, you create a reliable grounding system that enhances the safety of the electrical installation. This practice minimizes the risk of electric shock and equipment damage by providing a clear path for fault currents to return to the ground, thereby allowing protective devices like circuit breakers or fuses to operate effectively. Connecting only the main grounding conductor would not provide adequate safety coverage for the entire system. It fails to account for the specific grounding needs of each branch circuit that may be present, potentially leading to hazardous conditions. Similarly, connecting only the grounding conductor linked to the outlet ignores other circuits that could pose risks if faults occur. Not connecting any grounding conductors entirely defeats the purpose of grounding, which is to safeguard both people and equipment from electrical faults. Overall, the practice of connecting all relevant EGCs within an outlet box is essential for creating a comprehensive grounding system that adheres to safety codes and standards, promoting electrical safety in the environment.
