Devices that need to be plugged into an electrical outlet should be connected to which of the following?

Devices that need to be plugged into an electrical outlet should always be connected to a ground fault circuit interrupter (GFCI). This is particularly important for devices used in areas where water is present, such as swimming pools or locker rooms. GFCIs are designed to protect against electrical shocks by immediately shutting off the electric circuit if they detect any imbalance in the electrical current.

When a GFCI is functioning properly, it can prevent serious injuries or fatalities by cutting off the power to the device before a person can receive a potentially harmful electric shock. This safety feature makes it essential in environments where the risk of water contact with electrical devices is high. While other options such as standard outlets, surge protectors, and extension cords can have their own uses, they do not provide the same level of protection against electrical hazards that GFCIs offer.
