After the neutral leaves a transformer, which of the following can be connected?

• A. Only the EGCs.
• B. Only the SBJ.
• C. Both the GEC and the SBJ.
• D. None of the above are permitted.

Answer: (D)

The correct response highlights an important principle related to grounding and bonding in electrical systems. After the neutral leaves a transformer, it is essentially part of a system where the bonding and grounding practices must adhere to specific codes to ensure safety and proper functioning. The neutral wire's primary purpose is to provide a return path for current, while equipment grounding conductors (EGCs) and system bonding jumpers (SBJs) serve to protect against electrical faults and establish a reference point for ground potential. When the neutral exits the transformer, the electrical code prohibits connecting it directly to EGCs or SBJs because this could create parallel paths for current, which could lead to safety hazards like improper fault operation and electric shock risks. Therefore, the situation described in the question is one where no additional connections can be made after the neutral has left the transformer, in compliance with safety standards and codes. This ensures that the system remains safe, effectively preventing potential electrical hazards.
