No, the convention of connecting line wires to the top screws and load wires to the bottom screws is specific to GFCI (Ground Fault Circuit Interrupter) outlets and does not apply to non-GFCI outlets.
GFCI outlets have additional functionality to protect against electrical shock by monitoring the current flow between the line and neutral wires. If an imbalance is detected, such as when current leaks to ground through a person, the GFCI quickly interrupts the circuit, preventing potential harm.
The top and bottom screws on a GFCI outlet are labeled "LINE" and "LOAD," respectively:
Line: The line side of the GFCI is where the power source is connected. This is where you would connect the incoming hot (black) and neutral (white) wires from the electrical panel.
Load: The load side of the GFCI is used to protect additional downstream outlets or electrical devices. If you have other outlets or devices you want to be GFCI-protected, you can connect their wires to the load side of the GFCI.
On the other hand, standard non-GFCI outlets do not have this distinction between line and load terminals, as they do not provide the same level of electrical safety. With non-GFCI outlets, you typically have two screws for the hot (black) wire and two screws for the neutral (white) wire, and it doesn't matter which wire connects to which screw.
However, it's crucial to ensure correct wiring when installing any electrical outlet. If you're uncertain about how to install an outlet, it's always best to consult a qualified electrician to ensure proper and safe installation. Electrical work can be dangerous if not done correctly, so safety should always be a top priority.
