Which of the following is NOT a common type of electrical outlet?

• A. GFCI outlet
• B. AFCI outlet
• C. USB outlet
• D. Power strip outlet

Answer: (D)

A power strip outlet is not typically classified as a standard electrical outlet. Instead, it functions as an extension of a wall outlet, providing multiple outlets in a single unit, often with a built-in circuit breaker or surge protection. While power strips are widely used for convenience in connecting multiple devices, they are not permanent wiring solutions like the other types of outlets. GFCI (Ground Fault Circuit Interrupter) outlets are designed to protect against electrical shock by interrupting the circuit when a ground fault is detected. AFCI (Arc Fault Circuit Interrupter) outlets protect against electrical fires by detecting arc faults in wiring. USB outlets are specialized outlets that provide direct charging capabilities for devices via USB connections. Each of these types—GFCI, AFCI, and USB—are recognized as standard electrical outlet types used in residential and commercial applications, unlike the power strip which is a temporary and portable solution.
