If power is going to the switch first, you'll place the hot conductor on one screw of the switch, with the conductor on the other screw going to the hot (generally copper colored) screw of the GFCI on the line side. The neutrals in the switch box will be wire nutted together, with the neutral conductor leading to the receptacle box going to the silver screw on the line side. Grounding is still done as common. If power is going to the receptacle box first, you'll have to run a switch-leg. In this case, the neutral entering the receptacle box will be placed on the silver screw on the line side, but the hot will be wire nutted to a new piece of Romex. Personally, I nut the black (hot) conductor to the white that heads up to the switch (of course, you tape the white conductor over with black electrical tape on both ends). Both the white and black in the switch box are landed on the screws of the switch, and back in the receptacle box, the black lands on the hot screw (generally copper colored) on the line side. Grounding is still done as common, don't forget to connect the ground in the switch leg so you can ground your switch box, too. Have you used a switched GFCI before? In my experience, it's a common problem in bathrooms that a GFCI is tripped when a light (which is on the protected, or load, side of the GFCI) is turned on. You may find that he GFCI trips out when you fire up your dust collection unit sometimes. All you have to do in this instance is to hit the "reset" button, but it can be an annoyance.

GFCI Combo Switch and Outlet Wiring Circuit Diagrams and Installation
As discussed before, GFCI also known as ground fault circuit interrupter is a protection device against electric shock which detects the ground faults and leakage currents especially in outdoor and watery areas such as bathroom, kitchen, laundry etc.

In our previous wiring tutorial, we have shown that how to wire a GFCI outlet with different protected and unprotected loads. The GFCI Outlet/Switch is different than the GFCI outlet as there are two outlet in a GFCI outlet and one outlet and one switch in the combo GFCI switch and outlet. There are additional two wires on the back side of GFCI Combo switch/outlet and we will show how to use them to control the different loads or GFCI combo itself.
For more details, see the NEC Code Requirements for GFCI.
What is GFCI Combo Switch/Outlet and How to Wire It?
Before installation, it is must to differentiate between a GFCI Combo Switch Outlet and ordinary Combo switch/ outlet . In both outlets, the Line (live, hot or phase) terminals are narrow blade while Neutral terminals has wide blades. In a GFCI outlet, there is no break away fin between the upper and lower terminals as like in normal combo outlet for line terminals. In normal combo switch-outlet, the line should be connected to the one Line terminal which is interconnected via break away fin i.e. both terminals are internally connected. The second i.e. wide blade of outlet should be connected to the neutral wire and load can be connected through the switch.
In today wiring tutorials, we will be showing how to wire and install a GFCI combo switch and outlet in residential areas to protect the light switch, ordinary outlet / receptacle, light and switches and use the switch in the GFCI combo to control the outlet in it. You may also read the basic difference between GFCI and AFCI in the previous post.

Wiring a GFCI Combo Switch Outlet with a Light bulb
In the first wiring diagram, the connected load (as light bulb) is GFCI protected as it is control by the combo switch and connected to the load terminals of GFCI.
In the second wiring diagram, the lamp is connected directly to the line terminals of GFCI (i.e. direct main power supply). This way, the light can be control by the GFCI switch but it is not GFCI protected load.
Wiring a GFCI Switch/Outlet with an Ordinary Outlet / Receptacle
Same as the above wiring, the ordinary outlet / receptacle is GFCI protected and controlled by the switch as it has been connected the load terminals of GFCI.
In the following wiring diagram, the ordinary outlet is control by the GFCI switch but not GFCI protected as it has been connected and wired to the line terminals of GFCI.
Wiring a GFCI Combo Switch/Outlet with Protected Light & Outlet Receptacle
In this special case wiring diagram, Both light and ordinary outlet is connected to the load terminals of GFCI. The light ON/OFF operation can be controlled through the GFCI switch while the ordinary outlet is directly connected to the GFCI load terminals. This way, both loads i.e. light bulb and outlet and additional load connected to the ordinary load is GFCI protected.
In the following related wiring diagram, the ordinary outlet is connected to the load terminals of GFCI while the light bulb is connected to the line terminals of GFCI. This way, the ordinary outlet receptacle is GFCI protected while the light bulb is not GFCI protected.
Wiring a Switched GFCI Combo Outlet
In this wiring tutorials, the switch in the GFCI combo switch – outlet has been controlled through the switch in it. In other words, the outlet in GFCI can be turn ON/OFF via upper switch in the GFCI combo.
To do this, simply connect the upper wire (there are two builtin wires on the back side of GFCI) to the line terminal of GFCI while the second wire should be wired to the incoming line (phase, live or hot) wire. Connect the ground / earth terminal to the ground wire from the main board. This way, the outlet in the GFCI can be controlled (ON/OFF operation) through the switch in the GFCI combo.
- Switch off the main circuit breaker to make sure the power supply is OFF before wiring a GFCI outlet.
- Use the suitable voltage and ampere rating of switch with appropriate wire size and proper size MCB according to the load rating.
- Use the correct polarity i.e. verify the Load and Line terminals while installing a GFCI for protection. In other words, connect the wires to the correct side of outlet for proper operation.
- Regular maintenance, check and test is recommended while test the portable GFCI before each operation.
- Contact the authorized and licensed electrician for GFCI installation if you are not sure about the wiring diagrams.
- We have used Red for Hot, Black for Neutral and Green for Ground for illustration only. Follow your own area wiring color codes according to NEC, IEC etc.

GFCI Switch/Outlet Wiring Diagrams
Wiring a GFCI Outlet and Light Switch
This wiring show the connections for a gfci outlet switch combo used to control an unprotected light fixture.
Here, the source hot wire is spliced to the LINE hot terminal on the combo and one of the built-in switch wires. A 2-wire cable runs from the GFCI device to the light fixture and the black wire is spliced with the other built-in switch wire. At the fixture the black wire is connected to the hot terminal on the light. The source neutral is spliced with the LINE terminal on the GFCI and the white wire running to the neutral on the light fixture. The LOAD terminals on the GFCI remain available to connect more receptacles or other protected devices.
