_________ is an example of an electrical safety device that you may encounter when working as a beauty and wellness professional in a salon or spa.

• A. Ground fault circuit interrupter
• B. Surge protector
• C. Extension cord
• D. Circuit breaker

Answer: (D)

Electrical safety devices protect people and property by cutting power when something goes wrong. A circuit breaker does this by sitting in the main electrical panel and automatically disconnecting a circuit if the current becomes too high or a short is detected. That prevents wiring from overheating and reduces the risk of fire, which is especially important in a salon or spa where high-wattage tools are used. You may encounter a breaker that trips and needs resetting after an overload, which is a common safety reminder in these settings.

Surge protectors guard against voltage spikes for connected devices but don’t shut down the circuit; extension cords simply extend reach and can create hazards if overloaded; ground fault circuit interrupters are also safety devices—often used in wet areas—but the typical built-in protective device you’ll interact with in the salon’s electrical system is the circuit breaker.
