What is the maximum number of appliances that should be plugged into an outlet?

The correct choice is based on safety guidelines regarding electrical outlets and the risk of overloading circuits. In general, plugging in too many appliances into a single outlet can lead to overheating, potential fire hazards, and tripped breakers. The recommendation to limit to two appliances tends to minimize those risks while allowing for reasonable use of electrical devices in a nail salon setting. This practical guideline helps ensure that each appliance can operate efficiently without drawing excessive current that could compromise the outlet’s capacity.

It's important for professionals, especially in environments with multiple electrical devices, like nail salons, to adhere to these electrical safety standards to protect both themselves and their clients. Limiting the number of appliances plugged into a single outlet can ensure the longevity of the outlet and the devices while maintaining a safe working environment.
