However, code-wise [ You are required to have a neutral splice at your switch box unless this lighting circuit will be located in a location where the switch does not serve a habitable room or bathroom, such as in an attic. So, as long as your lights aren't in a "habitable room or bathroom", you are able to go with this wiring diagram.
The other exception would be as long as you are able to get back to the box later on to add a neutral without disturbing the finish of the wall. Leaving grounds and neutrals out of the discussion: you need a black for your always-hot down to the switches, the red for the switched hot back to fixture 1. A quality electrical supply house will sell it by the foot. It's used for just this sort of application.
Now you can pull anything you want anytime you want. EMT because it's steel so it provides a ground - that's one less wire to pull. Pull single-conductor THHN because it lets you pull exactly what you need for the job, Your local electrical supply can give you unusual colors by the foot, so your work is clear - I'd use yellow and orange for the 2 switched hots.

According to your answers to these questions, open this Explanation and click the appropriate diagram to expand it:.Do you have a question about wiring a GFCI outlet? You can consult with our in-office electricians in Mesa Arizona free of charge. Give our local Mesa electricians a call; they will save you both time and money.
Free estimates are also available. Wiring a GFCI receptacle is a little more complicated than hooking up a regular outlet but easily learned once explained. You can also learn about wiring GFCI outlets in the following 7 steps.
Tools Needed. Materials Needed. At the circuit breaker box or fuse box, turn off the electrical power.
Confirm that the power is shut off with a voltage tester. Do not depend on the circuit breaker labels, often times these are mislabeled. Remove the 2 mounting screws that are securing the existing electrical outlet and pull it all the way out of the box. Disconnect the attached wires on the existing electrical outlet from the terminal screws.
Cut the ends off the wiring the previously connected portion and straighten them. Note: If only 1 black, 1 white and 1 green or bare wire are present in the electrical outlet box you can skip past this step. Pull the wires out of the electrical box and separate all black and white conductors so no one can contact another. Your green or bare conductors can and should remain spliced together. Turn the power back on and using your voltage tester, carefully touch the black probe to the ground wire.
Using the red probe on your voltage tester, touch each black wire until you find the live one. This is the identified hot wire and it will get attach on the line side brass terminal screw on your new GFCI outlet. Keeping the red probe in contact with the identified hot black wire, remove the other probe from the ground and touch each individual white conductor until voltage is detected again. This will be the identified white wire and it will get attached on the line side silver terminal screw on your new GFCI outlet.
Carefully cap off the ends of each of these identified conductors with your yellow wire nuts. Do not put any wires together, the power is still on!How to read Wiring Diagrams, part 2 of 2
Note: Line and load will be clearly labeled on the back of the GFCI outlet and often times the load side will be covered with a piece of tape. Refer to the diagram above about wiring GFCI receptacles for additional help.
Loosen the silver and brass terminal screws on the line side of the outlet. If more than 1 black and 1 white conductor are in the electrical box, also loosen the load side silver and brass terminal screws.
How to Wire a 3 Way Light Switch
Take the black hot wire the identified black one with the yellow wire nut on it. It gets attached on the line side brass screw. Take the identified white wire the white wire with the yellow wire nut on it. It gets attached on the line side silver screw. Take any remaining black wires and attach them on the load side brass screw. Take any remaining white wires and attach them on the load side silver screw. Take the bare or green wire and attach it to the green screw on the GFCI outlet.
You may have to splice these ground conductors together and add a small piece of wire to the splice. This is often referred to as a pigtail and it attaches to the ground screw. Fold the ground conductor into the electrical box first. It is best to try to position the ground furthest back in the box to avoid any unintentional short circuiting to the terminal screws. Next fold the white and black wires into the box.Amateurs us 12 ga for everything, thinking bigger is better.
To do your own wiring not recommendedyou can buy a detailed wiring book that incorporates the latest electric code. The book will not include your state and local codes. Be aware that faulty wiring causes many home fires. Faulty wiring can also be a shock hazard to you and your family. It would not be good to burn down your first home. Ask your insurance company if they will cover your claim if you do your own wiring.
Good luck. Comply with the codes and have your work inspected. Be very care taking advise here. I have seen some very dangerous and just plain wrong answers concerning electricity. You have a black, white, and bare copper. The 12 is the gauge of the wire and determines how much current it can carry. For 12 wire, it will carry 20A. Cut this off,and tape the ends closed, you do not need it, You would use it if you were wiring a V circuit.
I suggest that you get an electrician to do the work. You would hate to burn down the house when you just got it. The black is the hot and goes to the copper color lug.
This will be on the side with the shorter slot in the recepticle. The white goes to the other side, the one with the longer slot and the silver covered screws. The bare wire will go the green screw and is the ground. If you do decide to do the work, please be sure to turn off the power before you go getting in to it.
First, know this, household electrical kills more people than any other type of electrical. A very important thing to do is make sure it is off with an electrical tester Inductive and make sure someone isn't going to turn it back on when you are working on it.
Get yourself a basic electrical book at a hardware store.Ask a Question! See How to Wire it Right! Estimated Time: Depends on personal level experience, ability to work with tools, work with electrical wiring, and the available access to the project area.
Important: Modifying existing electrical circuits or installing additional electrical wiring should be done according to local and national electrical codes with a permit and be inspected.

3 Way Switch Wiring Diagram
The trick is that each circuit uses a different hot wire, but they share the common wire and ground wire. This technique is used more for lighting circuits.
Shut off power to the main power panel. At the first light fixture, connect the black wire to the light fixture's black wire and top the splice with a plastic splice cap. Connect the white common wire to the white common wire of the light fixture, but do not place a splice cap yet. Connect the ground wires if the light fixture has one. At the first light fixture, connect the common white wire that runs to the second fixture to the splice with all of the other common wires and add a splice cap.
Also, connect that ground wire to all the other ground wires and add a splice cap.
Residential Electrical Wiring Diagrams
Place a splice cap on the end of the black wire that runs to the second light fixture. That wire will remain unused.
Secure the first light fixture and move to the second light fixture. Place a splice cap on the black wire that runs back to the first light fixture. That wire will not be used. Connect the red hot wire to the black hot wire of the light fixture and add a splice cap.
Connect the ground wires if applicable and add a splice cap. Secure the light fixture and move to the main power panel. In the main power panel, choose to use either two separate circuit breakers for the red and black hot wires or a single double breaker that would shut off the red and black hot wires at the same time.
Remove the breaker cover and knock out a single or double slot in the cover. When using two separate breakers, connect the black hot wire to one breaker and connect the red hot wire to the second breaker. When using a single double breaker, connect the black wire to first terminal on the breaker, and connect the red wire to the second terminal on the breaker.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. This page contains wiring diagrams for household fans including: ceiling fans and light kits, dimmer switches, fan speed controllers, 3 way fan switches, and bathroom exhaust fan circuits.
This is true of most Hunter and Harbor Breeze ceiling fans found at your local home store. The black wire is usually the hot for the fan and the blue wire is the hot for the light.
The white wire is the neutral for the fixture and the green is the ground. The white wire from the fixture is connected directly to the source neutral wire, either at the fixture box or through a splice at the switch box. The ground wire is spliced to the source ground and to any outlet box terminal using a pigtail. In some household circuits, the white wire may also be used to substitute for a hot wire.
In these cases, it should be wrapped with black electrical tape or otherwise marked to identify it as hot. This wiring diagram illustrates the connections for a ceiling fan and light with two switches, a speed controller for the fan and a dimmer for the lights. The source is at the switches and the input of each is spliced to the black source wire with a wire nut.
From the switches, 3-wire cable runs to the ceiling outlet box. At the switch box, the black wire is splice to the output on the speed controller and at the other end to the black fan wire.
The red wire is spliced to the output on the dimmer and at the other end to the blue light wire. The neutral from the source is spliced in the switch box with the white wire running to the fan and at the other end to the neutral wire on the ceiling fixture. Likewise, the ground wire is connected to any grounding terminals in the switch box and spliced to run to the fan location.
