What does a small slot in a receptacle outlet represent?

A small slot in a receptacle outlet represents the hot or ungrounded supply. In standard electrical wiring configurations, a receptacle typically consists of three slots: one for the hot (ungrounded) wire, one for the neutral wire, and one for the ground connection. The orientation of the slots is significant; the smaller slot is designated for the hot wire. This is crucial in ensuring that devices plugged into the receptacle receive the correct voltage and function safely. The hot slot allows the flow of electrical current, bringing power to devices, which is why its identification is critical for both safety and proper operation. Recognizing the correct functions of receptacle slots helps in understanding proper electrical installations and adhering to safety standards.
