They are also known as safety switches. GFCIs and RCDs are used to protect against electric shock in case of ground faults and leakage currents and trip the circuit. According to IEC and NEC, it is must to use and install these devices in watery areas like laundry, kitchen, spa, bathroom and other outdoor installation.
Now, you have got the idea as we are going to show different wiring circuit diagrams for single pole, two poles, three poles and four poles both single phase and three phase RCD RCCB or GFCI circuit breakers. Keep in mind that the the difference between single pole and two poles normal circuit breakers and a GFCI is that there is a builtin white wire on the back side of GFCI and it must be connected to the neutral busbar in the mains supply or it will not work and protect the circuit properly.
The following wiring shows an ordinary outlet has been wired and protected through single phase single pole GFCI circuit breaker. The builtin white wire in the ground fault circuit interrupter circuit breaker should be directly connected to the incoming supply neutral bar in the home mains distribution board or it will not work otherwise.
The GFCI breaker load neutral has been connected to the load terminal of outlet. The ground terminal of outlet is connected to the ground bar in the mains distribution board. The same wiring can be done for V, 13A circuit using the correct wire size, proper circuit breaker rating and suitable rating of switches and outlets. The following wiring shows an ordinary outlet has been wired and protected through a double pole GFCI circuit breaker.
The two wires as output hot and neutral are connected to the line terminals of ordinary outlet. In case of V and V, the same wiring diagram should be follow expect only one line L 1 or L 2 should be connected as hot to the input terminal of GFCI.
The following wiring shows hot water tub spa or whirlpool spa has been wired and protected through a three pole GFCI circuit breaker.
As we know that in V, there is no need to connect the neutral, but in some cases the appliances should be connected to the neutral according to the needs provided by the manufactures and user manuals. This is a 4 wire GFCI wiring diagram. As mentioned above, the builtin white wire has been connected to the neutral busbar in the main DB.
As shown in the fig, the three output terminals has been connected to the SPA control box followed by the printed marking i. At last, the ground wire from ground busbar has been connected to the ground terminal in SPA control box. The lower four terminals and ground wire of RCBO has been connected to the spa control box by the following sequence. In case of three phase spa wiring, use 12 or 10 gauge wire size for each line.
For example, use 12 or 4. Use 8 or 6. In case of higher wattage, use the proper wire size according to the table and use manual. Related Wiring Installation Diagrams and Tutorials:.

GFCI devices are especially useful for cord connected appliances and equipment used outdoors or near water. The following figure shows what a GFCI is and how to wire it? As shown in the above fig, 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 outlet.
In GFCI, the Load and Line Terminals marking should be verified by the nameplate date rating printed on it or by user manual provided by the manufacturer. In simple words, only two outlets in the GFCI are protected. In the first diagram, the single way switch and light bulb is connected to the load terminal of GFCI. This way, the switch and light bulb is GFCI protected. In the second diagram, the light switch is connected to the line terminals of GFCI. It means, the light switch is not GFCI protected and will operate as a normal circuit.
In the following diagram, the normal outlet is connected to the direct line supply i. This way, the ordinary outlet is not GFCI protected. It means, all the connected loads to the load terminals of GFCI are protected. The toggle switch in the combo switch outlet controls the first light bulb while the single way switch controls the second bulb. In short, all the loads is GFCI protected. In the following diagram, the above load mentioned before i.
This way, the combo switch — outlet, light switch and ordinary outlet are not GFCI protected. You can add more loads according to your needs but keep in mind that the maximum allowable number of boxed per circuit breaker is 12 where one circuit consists of all boxes on one circuit breaker. In addition, see the following general rules of thumbs and safety precautions for GFCI installation as well.

An initial look at a circuit layout may be confusing, however if you can review a subway map, you can read schematics. The purpose is the very same: getting from point A to point B. Literally, a circuit is the path that permits power to circulation. Voltage: Measured in volts Vvoltage is the pressure or pressure of power. This is usually provided by a battery such as a 9V battery or mains electrical energy, the electrical outlets in your home run at V.
Electrical outlets in various other nations operate at a different voltage, which is why you need a converter when traveling. Current: Existing is the circulation of power, or more specifically, the flow of electrons.
It is gauged in Amperes Ampsand also could just move when a voltage supply is linked. Resistance: Gauged in Ohms R or Oresistance defines just how easily electrons could move through a product.
Materials such as gold or copper, are called conductors, as they conveniently enable circulation of movement reduced resistance. Plastic, wood, and also air are instances of insulators, inhibiting the activity of electrons high resistance.
DC Direct Current. DC is a continuous circulation of present in one instructions. DC can stream not simply via conductors, however semi-conductors, insulators, and even a vacuum cleaner. Air Conditioning Alternating Existing. In Air Conditioning, the flow of existing regularly alternates between two instructions, usually creating a sine wave.A typical application for this method would be to protect more than one bathroom, or the all of the receptacles in your garage.
Below you will see some photos of recent projects that I have selected to help you with your project. Question: Chad, from Louisville, Kentucky asks: I recently installed a new electrical outlet on a kitchen wall that previously had none.
I basically ran the new wire down to our basement and tapped into an existing box that is running two additional outlets. I flipped the power on, plugged in the toaster oven and microwave and the clocks on both power up. However, when I run either of the two appliances, they tend to work for about minutes and then stop. It doesn't trip the breaker, but the outlet simply quits working. Without doing anything, the outlet will turn itself back on after about 10 minutes or so I know this as the clocks on the appliances power back up.
Could it be the fact that I have plugged in two appliances that surge which is causing this to happen? Why would they work for a bit and then stop but then work again? I am very confused. Answer: My first thought is to identify the circuit that you have tapped into and find out where that circuit originates from and if there could be any problems occurring with that circuit.
GFCI outlets do not do well when they are overloaded. You have not mentioned, but it may be that the GFI outlet is rated for 15 amps and the circuit is actually a 20 amp circuit. If this is the case then installing a 20 amp rated GFI outlet may solve the problem. Question: Using the feed through method, is there a limit on either the number of downstream receptacles or the distance beyond the GFCI outlet? Answer: You can add any reasonable number of outlets, the concern is to stay within the amperage load of the circuit, distance is not a problem as long as your under feet, depending on the connected types of load placed on the circuit.
Question: This feed through is really good, but how would I wire it if it were a quad with a GFCI in the first position to protect all 3 standard down stream outlets? I would like to put in two quads. Do I just use short wires to connect the outlets in each quad together? Thanks, Dan. Answer: Yes Dan, It's basically the same wiring as shown except that you are wiring the LOAD side out to all your outlets and they may be connected by making jumper wires or tails from each set to one connection for the LOAD Set of wires.
Does it say on the outlet? You will also notice that on a 20 amp GFCI Outlet the left or neutral plug opening will have both the vertical and horizontal opening for a 20 amp plug.

You may notice that with some brands of 15 amp GFCI Receptacles have a 20 amp rated feed through, therefore a 15 amp GFCI receptacle may be installed on a 20 amp circuit.
When installing downstream outlets from a GFI should these be used? This is new construction in Indiana. Thanks Charlie. Answer: Dave's Reply: The square design that you are referring to for the other outlets is just a different decorative design and really does not have any significance to GFCI protection that is provided by the GFI outlet.
The design of the GFI outlet was adopted most likely because of the extra space that was needed for the ground fault circuit components. The GFCI is rated for 20 amps and it is protecting my new 12 amp hot tub. Could the new hot tub be a lemon? Answer: Keep in mind that the existing circuit rating should be identified. Check to see if the hot tub requires it's own dedicated circuit. Sharing a circuit with a hot tub could cause nuisance tripping of a GFCI outlet if the circuit is loaded up to capacity.
The hot tub could be tested for possible inconsistencies, and it may help to search for feedback about the reliability of the unit as well. Somewhere between the GFI and the wire in the garage the wiring has changed from Romex to the old style with 3 black stranded wire.
GFCI Outlets, How To Wiring Diagram
I tried to wire a GFI into this wire making sure the hot went into the hot terminal, and determining that another wire was the neutral, and the third being the ground. When I install the GFI this way the tester shows that it is installed correctly until we push the GFI test button on the tester and then it says that the Hot and neutral are reversed.
When you reverse these wires it still indicated that the hot and neutral are reversed.This is not entirely the case. The GFCI does not rrequire a ground to function as it is sensing the current in both the supply and return leg is within 5 mA of each other. Louis County still uses NEC and does not modify this rule in their own code.
All St. Louis municipalities, likewise…but get a hold of the actual code for the City of St. They write their own electrical code and this may not be allowed in it.
The tester needs a ground to be able to simulate a leak to cause it to trip. It will still trip if there is an actual current leak or if you use the device test button which does not require a ground to work. I believe that the on-board test button uses a resistor to simulate a leak.
The NEC requires receptacles installed on 15 and 20 ampere branch circuits to be of the grounding-type and it requires the grounding contacts of those receptacles to be effectively grounded to the branch circuit equipment grounding conductor .
Yep, lets not forget the structure of the NEC and other documents. The test button does not trip the breaker. This is due to no ground being in the system.
Using 2 screw drivers is the easiest and most convenient thing to do when that is all you have to see if what you did is correct. We wired the wires correctly to the plugs everything works great when they are plugged in. But we wanted to be sure what was supposed to pop when it gets overloaded or a change in 5mA. Even on a 2-wire system with No ground. Apparently the receptacles are improperly wired, or faulty.
The test button has nothing to do with tripping the breaker. It simply shunts the current to the grounding conductor.By code, the number of conductors allowed in a box are limited depending on box size and wire gauge. Calculate total conductors allowed in a box before adding new wiring, etc. Check local regulations for restrictions and permit requirements before beginning electrical work. The user of this information is responsible for following all applicable regulations and best practices when performing electrical work.
If the user is unable to perform electrical work themselves, a qualified electrician should be consulted. How to Read These Diagrams.
