What signifies that an outlet is correctly wired and functioning?

An outlet is considered correctly wired and functioning when it can supply power to appliances. This ability indicates that the outlet is connected properly to the electrical circuit and that the wiring is intact, allowing electrical current to flow. When an outlet can deliver power, it confirms that the internal connections are secure, and the outlet is part of a functional electrical system. This functionality is essential for the proper operation of any devices or appliances plugged into the outlet, thereby confirming its reliability.

While being covered with a junction box may indicate safety and compliance with electrical codes, it does not directly confirm that the outlet is operational. Similarly, a visible symbol on the plan may indicate where the outlet is located, but it doesn't provide evidence of its operational status. Lastly, the outlet's distance from wet areas is a consideration for safety and code adherence, but again, it does not directly relate to whether the outlet is functioning correctly. The primary indication of an outlet being correctly wired is indeed its ability to supply power, making it usable for appliances.
