What is the interrupting current of a GFIC receptacle?

• A. 3-4 mA
• B. 5-6 mA
• C. 7-8 mA
• D. 9-10 mA

Answer: (B)

The interrupting current of a Ground Fault Circuit Interrupter (GFCI) receptacle is typically set at a level designed to protect individuals from electrical shocks. The correct choice, indicative of the standard operation range for a GFCI, is 5-6 mA. This range is crucial for the safety function of a GFCI receptacle. If the ground fault current exceeds this threshold, the GFCI is designed to trip, disconnecting the power to prevent any harm to individuals who may be exposed to electricity in a wet or conductive environment. The choice of 5-6 mA is backed by safety standards, which stipulate that this interrupting current is effective in providing protection while minimizing nuisance trips under normal conditions. Therefore, recognizing the critical role of GFCIs in safety applications, the 5-6 mA threshold aligns precisely with these safety standards and reflects the correct understanding of the GFCI's functioning.
