If you’re installing or replacing a GFCI outlet, you may have asked what is the difference between GFCI line vs load.
These terms refer to the different sets of wires that connect to the outlet and understanding the difference between them is crucial for a safe and effective installation.
The line wires are the incoming power wires that provide electricity to the outlet.
These wires are typically black and white, but can sometimes be red or blue.
The load wires, on the other hand, are the wires that carry power to other outlets downstream from the GFCI outlet.
These wires are also typically black and white, but may be a different color depending on the wiring configuration.
It’s important to correctly identify which wires are the line wires and which are the load wires, as connecting them incorrectly can result in the GFCI outlet not functioning properly or even creating a dangerous electrical situation.
In the next section, we’ll go over some tips for identifying the line and load wires when installing or replacing a GFCI outlet.
GFCI Line Vs Load
When it comes to installing a ground fault circuit interrupter (GFCI) outlet, it’s important to understand the difference between the line and load connections.
The line terminals are where the power comes into the outlet, while the load terminals are where the power is carried to downstream outlets.
Line Connections
The line terminals are where the power comes into the GFCI outlet from the electrical panel.
These terminals are typically labeled “line” or “hot” and “neutral.”
The black wire should be connected to the hot terminal, while the white wire should be connected to the neutral terminal.
Load Connections
The load terminals are where the power is carried to downstream outlets.
These terminals are typically labeled “load” or “hot” and “neutral.”
If you want the downstream outlets to be protected by the GFCI outlet, you must connect the wires to the load terminals.
It’s important to note that if you connect a downstream outlet to the line terminals instead of the load terminals, it will not be protected by the GFCI outlet.
You must connect the downstream outlet to the load terminals in order for it to be protected.
Wiring Tips
When wiring a GFCI outlet, there are a few important tips to keep in mind:
- Always turn off the power before working on electrical wiring.
- Make sure to follow the manufacturer’s instructions for wiring the GFCI outlet.

- Locate the GFCI outlet.
- It will have two buttons in the center: a “test” button and a “reset” button.
- Press the “reset” button.
- If it clicks, the outlet has been reset.
- If the outlet won’t reset, try pressing the “test” button first, then the “reset” button.
- If that doesn’t work, you may need to call an electrician.
Identifying Load Line Wiring Errors
If your GFCI outlet is wired incorrectly, it won’t work properly.
Here are some common wiring errors and how to fix them:
- Reversed line and load wires: If the line and load wires are reversed, the GFCI outlet won’t work.
- To fix this, switch the wires so that the line wire is connected to the line terminal and the load wire is connected to the load terminal.
- Load wires connected to line terminals: If the load wires are connected to the line terminals, the GFCI outlet won’t work.
- To fix this, disconnect the load wires from the line terminals and connect them to the load terminals.
- Multiple wires connected to a terminal: If there are multiple wires connected to a terminal, the GFCI outlet won’t work.
- To fix this, remove the wires and connect them to a pigtail, then connect the pigtail to the terminal.
Remember, if you’re not comfortable working with electricity, it’s best to call a licensed electrician to help you troubleshoot your GFCI outlet.
