What must GFCI-type receptacles indicate if installed where a grounding-type receptacle is absent?

• A. GFCI Functional Only
• B. Protected from Ground Faults
• C. GFCI Protected and No Equipment Ground
• D. No Equipment Ground Only

Answer: (C)

The correct response is that when GFCI-type receptacles are installed in locations where a grounding-type receptacle is absent, they must indicate that they are "GFCI Protected and No Equipment Ground." This is important because GFCI (Ground Fault Circuit Interrupter) devices provide protection against ground faults by monitoring the current flowing through the hot and neutral wires. However, in scenarios where an equipment ground is not present, it's essential to clearly communicate that the receptacle offers GFCI protection without a ground, which is a common setup in older buildings or certain areas. By indicating "GFCI Protected and No Equipment Ground," users understand that the receptacle offers individuals protection from electric shock due to ground faults, but they should not rely on it for grounding purposes. This differentiation helps prevent misunderstandings about the protection level and proper use of equipment that may be connected to the GFCI, ensuring safe practices in environments with limited electrical grounding.
