What type of receptacles must be GFCI protected when installed within 6 feet of a wet bar, laundry, or utility sink?

In residential wiring, GFCI (Ground Fault Circuit Interrupter) protection is crucial in areas where there is an increased risk of electric shock due to moisture. When outlets are installed within 6 feet of a wet bar, laundry, or utility sink, both 15-ampere and 20-ampere receptacles must be GFCI protected. This requirement is set forth in the National Electrical Code (NEC) to enhance safety in environments where water is present, as water and electricity can create dangerous combinations.

The reasoning behind this regulation is that GFCI devices monitor the electrical current flowing through the circuit. If they detect an imbalance, which may occur if a person comes into contact with a wet surface while using an appliance plugged into the receptacle, they immediately cut off the power. This can prevent serious injury or fatality due to electric shock.

Thus, it is essential for both 15-amp and 20-amp receptacles in areas near water sources to have GFCI protection to ensure that safety standards are upheld in residential electrical installations. This applies to the wide range of receptacle types commonly used in homes, including standard duplex receptacles, which are frequently installed in these high-risk areas.
