Can you wire multiple lights from one junction box?
You can do this light switch wiring in one of two ways. The most common is to daisy-chain the light fixtures by connecting them to each other and hooking the first one up to the switch. The other way to wire multiple lights to one switch is to connect all of them directly to the switch in a "home run" configuration.

Should you wire lights in series or parallel?
The common household circuits used in electrical wiring installation are (and should be) in parallel. Mostly, switches, Outlet receptacles and light points etc are connected in parallel to maintain the power supply to other electrical devices and appliances through hot and neutral wire in case if one of them gets fail.

And you're also going to repeat this process when we start hooking up the hot wires.
Can two ground wires touch each other?
The reason that wiring devices have grounding connections that accept only one wire is that otherwise, if two ground wires were connected to the device, then if someone later removed that wiring device and then re-applied power without wire-nutting the grounding conductors, there would be a break in the ground path for ...
Do light switches need to be grounded?
Grounding light switches have become commonplace, used as a preventative safety measure. It is perfectly legal to wire a light switch without the inclusion of a ground. Dimmers will require a ground wire but traditional toggle-type switches will not. Omitting a ground wire on any switch is not recommended.
Do ground wires need to be connected to each other?
No matter the method, it's important that the ground circuit provides an unbroken path to the earth. Ground wires must be firmly connected at all points. And if conduit or sheathing is used as a ground path, connections must be tight.
What wires bypass a switch?
The white, or neutral, wires bypass the switch, so the one coming from the power source and the one from the light get spliced and capped in the box. The ground wire, on the other hand, must connect to both switches, and the easiest way to do this is to make a pigtail as you did with the hot wires. Advertisement.
Why do three way switches have extra terminals?
A three-way switch has an extra terminal because a pair of three-ways has to be connected to each other as well as to power and the light. You can see a diagram at Electrical 101. The cable you use to connect three-way switches to each other has three conductors and a ground, and the extra conductor is usually red.
How to make a pigtail with two wires?
You make a pigtail by twisting the three wires together and screwing on a wire cap to insulate the connection .
What is the red wire on a light switch?
The red wire connects one set of brass terminals on the two switches, and the black wire connects the other set. The bottom terminal on one of the switches is used for the black wire coming from the power source, and on the other switch, it connects to the black wire going to the light. Advertisement.
Where is the pigtail wire in a switch?
Make the pigtail in the box into which the line cable enters, or Box 1. One wire in the pigtail is the line wire and one goes to the switch in Box 2, and the third is a single jumper wire needed to hook up the switch in Box 1.
Can you wire two light switches?
You can wire two light switches with one power supply. Image Credit: Grace Cary/Moment/GettyImages. It's common to power two or more light switches from a single power supply, and the switches can be in the same electrical box or different parts of the house. The power source is typically the building's main electrical panel.
Can two light switches control one light fixture?
Two light switches connected to the same power source can control a single light fixture too. In this configuration, the switches are called, confusingly, three-way switches. It is recommended to contact an electrical professional to take care of any of your wiring needs.
How to connect a gang box to a gang box?
Connect the three white wires inside the gang box together by twisting a red wire connector on all three wires. Connect the three bare copper wires together with another red wire connector. Push these two sets of wires into the back of the gang box.
Can you add a light fixture to a gang box?
Adding an additional light fixture and powering it from an existing gang box is not complicated if you expand the existing gang box and power both lights with separate switches. Some gang boxes are in locations that do not allow the box to be expanded to add a separate light switch.
Can you wire two single pole lights in the same box?
You can wire two single pole light switches in the same gang box using a device that combines two separate single pole light switches into one device, using the original single switch space. Advertisement.
How to connect two black wires to a switch?
Slice open a spare length of cable that is 6 inches long with a utility knife and remove the black and bare wires. Remove 1/2 inch of insulation from both ends of the black wire. If you've mounted two switches in the same electrical box, prepare two black wires. Connect one end of the 6-inch wire to the top terminal of the first switch.
How to connect a second switch to a pigtail?
Twist the other end together with the black wire from the incoming circuit cable and the black wire from the cable going to the second switch to form a pigtail. Twist a wire cap onto the end of the pigtail. Use the other 6-inch wire to connect to the top terminal of the second switch if it is mounted in the same electrical box. ...
How to connect a switch to a ground terminal?
Connect the 6-inch length of wire to the green ground terminal. Twist the other end together with the ends of the three bare wires in the box. If the switches are in the same box, connect the ground terminals with one 6-inch wire and twist that wire together with the other two. Twist all the white wires in each electrical box together and cap them.
How to connect a 12 gauge cable to a switch?
Pull a 12-gauge cable from the power source, making sure that the power is off and the cable is dead. Feed it through the back of one of the switch boxes and strip the wires. Run a second 12-gauge cable from the first switch to the second one and strip the wires on both ends.
Can you wire two lights and switch?
It isn't unusual to wire two or more light and switch combinations from the same power source -- in fact, it's common practice. Typically, the source is a circuit breaker in the main electrical panel that has a rating large enough to handle the lights.
Can you mount a switch side by side?
You can mount the switches side-by-side in a double-gang electrical box or in different locations, each in a single-gang box. For each fixture and switch you have the choice of nailing a rough-in box to a stud or rafter or mounting a remodeling box on the drywall. Run 12-gauge electrical cable between each switch and the light it controls.
