Snap switches are considered to be part of the effective ground-fault current path when which condition is met?

• A. They are installed in a residential building
• B. They are not covered by insulation
• C. They are connected to a dedicated circuit
• D. They meet specific installation criteria

Answer: (D)

Snap switches are considered to be part of the effective ground-fault current path when they meet specific installation criteria. This is important because the role of the effective ground-fault current path is to ensure that in the event of a ground fault, the fault current can properly return to the source of the supply, thereby allowing protective devices to operate correctly and help prevent electric shock or fire hazards. For snap switches, these installation criteria may include aspects like the proper bonding and grounding of the switch to the electrical system, ensuring the switch is properly mounted, and verifying that it is connected to adequately grounded conductors. Meeting these criteria ensures that the switch can effectively conduct any fault current, which is crucial for safety.
