Why would a light switch have two black wires for power and two whites caped off?

Black represents Hot and White common. For the light to operate it needs a white and black wires. The switch box has two cables with a white and black wire plus a ground. One wire is from the supply and the other to the light. Connecting the whites just provides common directly to the light. The blacks go into and out of switch because it is the hot side that is being switched.

Having two black wires connected to a light switch indicates that it is a switch loop, where one black wire brings power to the switch and the other black wire carries power to the connected light fixture. The two white wires capped off are neutral wires from the power source and the light fixture, which are typically not connected to the switch.

Have 3 lights Power to light 1 Need to connect light 2 then light 3 then down to single pole switch How do you wire?
You can connect the three lights in series by running a connected wire from the power source to light 1, then another wire from light 1 to light 2, and finally a wire from light 2 to light 3. From light 3, run a wire down to the single pole switch to complete the circuit. Make sure to connect the neutral wires together at each light and the switch.
How do you connect multiple lights to one switch starting at the light?
To connect multiple lights to one switch starting at the light, you will need to run a cable from the first light fixture to the switch. Connect the hot wire to the switch, along with a pigtail wire to connect to each light. Then connect each light fixture to the pigtail wire to create a parallel circuit. Make sure to follow proper safety precautions and consult a professional if needed.
How do you wire a light and switch with the 2 wire old romex?
To wire a light and switch using 2-wire Romex, connect the black wire to the brass screw on the switch, the white wire to the light fixture, and the white wire to the silver screw on the switch. Make sure to cap the unused wire at both ends for safety. Be sure to turn off the power before starting and consult a professional if you are unsure.
How do you connect two way electrical switch?
The two way switches work in pairs. We find most of them in our houses where the light bulb can be operated by two switches each at the far end to the other. Each switch consists of three terminals two of which are connected. When one switch is open and the other is closed then the bulb glows and viceversa
How do you wire a basic off switch to a light?
To wire a basic off switch to a light, you will need to connect the switch in line with the hot wire (typically black) leading to the light fixture. The wiring involves cutting the hot wire and connecting each end to the terminals on the switch. Make sure to turn off the power supply before working on the wiring for safety.
I have four outside light fixtures on the same circuit The first box has a black a white and a bare wire coming into and out of it The light itself has a black a white and abare How do you wire this?
If you are down stream from the switch then all blacks together, all whites together and all grounds (bare wires) together.

Can you change an electrical outlet into a switch for a light?
Sure. For a light you need a fixture to hold the light and the light itself. The light needs to be connected to a voltage supply which you can get from the outlet. In the outlet box you will have a black, white and bare ground wire. Essentially you connect the white and bare wires directly to the light and switch the black wire (hot) through a switch.

How do you remove 240 volt light sensor and return to switch operation?
To remove a 240-volt light sensor and return to switch operation, you can simply disconnect the light sensor wires and reconnect the original wires for the switch. Make sure to turn off the power supply before doing any electrical work and follow proper safety precautions. If you are unsure, it's best to consult a licensed electrician for assistance.
Why can l only get power the the kitchen light switch when turning on the bathroom light switch?
It sounds like the feed for the kitchen is fed through the bathroom switch box. The black feeding the kitchen light is connected to the wrong side of the switch. There should be two black on one side of the switch and one on the other. One of the two blacks need to be moved to the other side of the switch. **BE VERY CAREFUL or CALL A LICENSED ELECTRICIAN** Even with the switch OFF the live side of the switch will be LIVE!!
How do you hook up one light to one switch in a basement lighting system that has all 10 lights connected to one switch?
If you have good access to the wiring this is relatively easy to do. Each of the 10 lights is connected to another in parallel in a "daisy chain" fashion. Light 1 is connected to the switch, light 2 is connected to light 1, light 3 is connected to light 2 and so forth. Let's say it is light 5 that you wish to switch separately. You can first install the new switch by either adding a new box or modifying old switch box. There are two gang switches that will fit the form factor of a single switch. TURN OFF THE POWER TO SWITCH BOX. Using the same supply input at original switch, add a new black wire to the wire nut for input to original switch and connect this to the input of new switch. Then run a new wire to light 5 and connect black wire to the output of new switch. Connect all the white wires together in switch box and separately connect all bare wires together in switch box. Now at light 5 undo the black and white wire coming from the fixture, and reconnect the wire nuts so that there is a direct connection between light 4 and light 6. Do the same for the ground if present (bare wire). You now have the fixture wires hanging free. Now connect the black wire from new switch to the fixture black wire and white to white and you are done.
