Yes.
Generally speaking you should use only existing knock outs. But it is certainly acceptable to make your own access. Be careful to use the correct connector, if required, and that your connector and wire do not interfere with installing the device safely into the box.
Yes, provided that you have a ground wire in the box and that the ground wire is properly connected in the electric panel.
Power into the first outlet and out to all other outlets, black to gold and white to silver screw, ground wires to ground screw. From the outlet closest to the light switch run power from that outlet up to the switch box. Run another wire from the switch box up to the light. In the switch box tie all the whites together under a wire nut and push them back into the box. Tie all the ground wires together and connect that to the ground screw on the switch. Connect the 2 black wires you have left to the 2 screws on the switch. Does not matter which if you only have power in and power out to the light.
More to the point is how are YOU going to get wire to and from the box. Installing the box is the easy part. You first find a stud and measure the box dimensions onto it with one side almost touching the stud. Now, using a 'Keyhole' saw or drywall saw, cut out the box shape. At this point, I insert a 'fish' tape and pull the wire through, usually from the top. I pull the wire out enough to feed into the box and then push the box into the cut shape. Then screw the box into the stud obliquely, or if you've got an 'old work' box, turn the screws on the box to fix the 'ears' and secure the box. Now you can wire the outlet or switch in. -Turn off power first .
If the wiring system into which you are installing an outlet has no ground available, use an ungrounded outlet. In an ungrounded system, an outlet with a ground contact would allow the outlet user to mistakenly, and perhaps dangerously, assume that a ground was present. A suitable ground may be available as a ground wire accompanying the hot and neutral wires in the cable, or a ground may be available via conductive conduit and a metal outlet box. In any case, use a tester to confirm the integrity of the assumed ground. A voltage test from the hot wire to the ground should show the same voltage as between hot and neutral (the black and white wires respectively). If you are replacing an ungrounded outlet, you need not assume there is no ground present. You may find, in the box, ground wires that were not connected to the outlet. You may come across grounded outlets that have no ground wire attached because they rely on grounding via the mounting screws through the outlet ears to the metal box. This is a less reliable grounding method. It is better to buy a ground-wire "pigtail," fasten the wire directly to a hole in the metal box with the supplied screw, and attach the other end of the ground wire to the outlet via the outlet's ground screw.
Just make it a junction box. Remove the outlet, tie the blacks together under a wire nut. The the whites together under a wire nut. Tie the ground wires together under a wire nut. Push all the wires back into the outlet box and cover it with a blank cover. Paint the cover the same color as the wall. Do not sheet-rock over the outlet box. All junction boxes must be accessible.
To run electrical wire from the breaker box to an outlet, you will need to turn off the power, plan the route for the wire, drill holes for the wire to pass through, run the wire through the holes, connect the wire to the breaker box and outlet, and secure the wire in place. It is important to follow all safety guidelines and local building codes when doing this task.
To safely and correctly install a 3 wire dryer outlet, follow these steps: Turn off the power to the circuit at the breaker box. Remove the cover plate from the outlet box. Connect the white neutral wire to the center terminal, the black hot wire to one of the side terminals, and the red hot wire to the other side terminal. Secure the wires with the appropriate screws. Attach the outlet to the box and secure it in place. Replace the cover plate. Turn the power back on and test the outlet to ensure it is working properly.
To wire an outlet, first turn off the power to the circuit. Remove the cover plate and outlet from the electrical box. Connect the black wire to the brass screw, the white wire to the silver screw, and the ground wire to the green screw. Secure the outlet back into the box, replace the cover plate, and turn the power back on to test the outlet.
To install a ground wire in an outlet, first turn off the power to the outlet at the circuit breaker. Next, remove the outlet cover and unscrew the outlet from the electrical box. Connect the ground wire to the green screw on the outlet and secure it with a wire nut. Finally, reattach the outlet to the electrical box, replace the cover, and turn the power back on at the circuit breaker.
To properly install and wire a switched outlet in your home, follow these steps: Turn off the power to the outlet at the circuit breaker. Remove the existing outlet from the wall. Install a new electrical box for the switch next to the outlet. Run a new wire from the outlet to the switch box. Connect the black wire from the outlet to one terminal on the switch. Connect the white wire from the outlet to the neutral wire in the switch box. Connect the black wire from the power source to the other terminal on the switch. Connect the ground wires together and to the switch and outlet. Install the switch and outlet back into the wall. Turn the power back on and test the switched outlet to ensure it is working properly.
To properly wire an outlet, first turn off the power at the breaker box. Remove the old outlet and connect the black wire to the brass screw, the white wire to the silver screw, and the ground wire to the green screw. Secure the wires with wire nuts and attach the outlet to the electrical box. Finally, turn the power back on and test the outlet to ensure it is working safely and correctly.
To wire an electrical outlet properly, first turn off the power to the circuit. Remove the cover plate and outlet from the electrical box. Connect the black wire to the brass screw, the white wire to the silver screw, and the ground wire to the green screw. Secure the wires with the screws and carefully tuck them back into the box. Finally, reattach the outlet and cover plate, and turn the power back on to test the outlet.
To wire an outlet safely and correctly, first turn off the power to the circuit at the breaker box. Remove the cover plate and outlet from the wall. Connect the black wire to the brass screw, the white wire to the silver screw, and the bare copper wire to the green screw. Secure the wires with the screws and carefully tuck them back into the outlet box. Finally, reattach the outlet and cover plate, and turn the power back on to test the outlet.
To wire a plug outlet correctly, first turn off the power to the outlet at the circuit breaker. Remove the cover plate and unscrew the outlet from the electrical box. Connect the black wire to the brass screw, the white wire to the silver screw, and the green or bare wire to the green screw. Tighten the screws securely and carefully push the outlet back into the box. Replace the cover plate and turn the power back on to test the outlet.
To wire a single toggle switch and outlet with a two-wire system, you will need to connect the hot wire (black) to the brass terminal of the switch. Then connect a short jumper wire from the brass terminal to the brass terminal of the outlet. Connect the neutral wire (white) to the silver terminal of the outlet. Finally, connect the ground wire (green or bare copper) to the green screw on the switch and the green screw on the outlet.
To wire an electrical outlet, first turn off the power to the circuit. Then, connect the black wire to the brass screw, the white wire to the silver screw, and the bare copper wire to the green screw. Finally, secure the outlet in the electrical box and turn the power back on to test the outlet.
To wire up an outlet properly, first turn off the power to the circuit. Remove the cover plate and outlet from the electrical box. Connect the black wire to the brass screw, the white wire to the silver screw, and the bare copper wire to the green screw.
