Line and Load Connections when Wiring GFI Outlets
- Receptacles that are called GFI, Ground Fault Interrupter, and GFCI Ground Fault Circuit Interrupter are the same and provide the same protection.
- The LINE side of the GFI Receptacle is for the Incoming circuit power.
- The LOAD side is the Outgoing power from the receptacle.
- The ground fault protection is provided at the receptacle, and additional receptacles and devices depending on the circuit wiring configuration.
- Make sure the GFI outlet Test and Reset buttons are functioning.
- If the Test and Reset buttons do not function then the wiring configurations is incorrect and you will need to double check your corrections.
- Make sure the incoming power source is attached to the Line side and the Outgoing wiring is connected to the Load side of the GFI Outlet.
EXAMPLE of the Line and Load side of a GFCI Receptacle
- The Line side and the Load is typically identified by lettering that is visible on the back side of the GFCI receptacle.
- As shown above with this Leviton GFCI Receptacle, yellow tape is placed over the LOAD side to prevent confusion, and the LINE side is open and ready for wiring.
