The second terminal of switch then connected back to the brass terminal of outlet. Take the outlet and start by connecting the ground wire to the green screw.
The black wire will go from the usb outlet directly to the switch.
How do you wire a usb outlet. Follow this procedure for all but the last outlet in the circuit. Securely attach the two wires provided with the usb outlet to that wire and pull them back down and through the hole where you will mount the new outlet. You can do this by curling the wire around the screw itself and tightening it.
If your usb outlet has prewired leads, use those in place of pigtails for that outlet. (2 small green wires used for the ground) the green wire will go from the green ground screw on the usb outlet to the green screw on the switch and then grounded into the metal housing box. You just reverse the whole process, but with the new outlet.
The white wire will get spliced from the usb outlet to the white wire. Ideally you want the wire to be a round cord but you can use electrical tape to create the bulk or squirt some silicone seal into the hole with the wires and then tighten down the fitting to compress the grommet and sealant around the wires. The hot side of the circuit (black wire) should be wired to the brass screws while the neutral side of the circuit (white wire) should be wired to the silver screws.
In order to extend this wire you will want to strip the plastic coating off the tips of each wire. Attach the black wire to the outlet you want to always be on (usually the top one) and the red wire to the switched outlet. In this wiring, a switch is added to to an existing outlet by removing the hot wire from outlet brass terminal and connected to the first terminal of switch.
Just take the stripped end of the wire, place it under the clamp, and tighten the screw on top of the. The black wires attach to the brass screws, the white wires attach to the silver screws, and the ground wire attaches to the green ground screw. The hardest part of the whole process is probably going to be fashioning the cover for the usb port, and that's really if you want it to look pretty.
Sometimes outlets have small holes on the back that you can stick the end of the wire into and tighten the screw down, but this isn’t always the case. It depends entirely on the design of the power supply built into the outlet, and there is a lot of room for variation. In today wiring tutorials, we will be showing how to wire and install a combo switch and outlet device in residential areas to control the lighting point, adding an outlet to the existing combo device, connecting switch and outlet from different sources, adding a gfci protected combo switch/outlet and use the switch in the combo device to control the outlet in it.
You’ll have three cables in the existing box: With many usb outlets, you can have two usb ports in every outlet, if you. (if you go that route, i recommend something like this.)
Reattach all the wires to your new outlet. You only want to create an opening through the interior paneling. If you wanted to ignore code and wire your outlets in series, the procedure would be the same.
A usb port is a standard cable connection interface for personal computers and consumer electronics devices. Connect the black wires to the brass terminals on the outlet you're wiring, connect the ground wires to the ground terminal, then twist the white wires together and cap them. One side of the receptacle has (2) brass screws and the other side has (2) silver screws.
Unless you can do that i would not install your new receptacle because you are creating a false sense of security by not having the ground leg of your receptacle tied to anything and anyone who comes along to plug something in could be tricked and possibly hurt or killed. Your 12v usb charger will come with a small length of black and red wire attached to it. Perhaps putting that in small electrical box to code as well.
You’ll do this for all of the wires. Then, measure and cut the length of red wire and black wire that you will need to. If you find it wrapped around a nail or screw on or around the jbox you can tie into it to create a true 3 wire grounded 120v circuit.
You can also use a wire cutter to cut the wires off, but you'll have to strip about ½ of sheathing to attach them to the new receptacle then. Some devices give you the option of a small brass clamp under the screw head. A power supply, a line feeding downstream outlets and your new cable.
You can now screw the outlet to the box and proceed to the switch box. Either that or essentially put an outlet inside the wall (instead of showing) that i simply plug the device in to like normal. Feed a stiff wire or hanger through the hole you cut toward and out of the existing hole for the fixture you removed.
Make a pigtail from each colored wire. Usb ports allow usb devices to be connected to each other with and transfer digital data over usb cables. If you’ve made it this far, the final step is the easiest:
Connect the pigtails to their corresponding terminals on each outlet. Do the same with the white wires connecting the white pigtail to the silver screw. Connect the white wire to either of the chrome screws (remember, they are still joined) and the ground wire to the green ground screw.
If you need to remove your old outlet, you can follow the directions in this post on replacing an ugly old outlet. Then wire that plug into the existing house wires like any other outlet. Here's one from lowes but you can get nylon on amazon (in bulk) and other places.
You must make a black pigtail (short wire), connect the two existing black wires together with the black pigtail using the proper size wire nut and then connect the black pigtail to the proper side of the outlet (dark screw). It also shows you how to install the outlet it if you are starting with a new construction junction box. Hit the link for the full instructions.
This way, the outlet is wired and controlled (on/off) through the switch. You only need to connect to (1) screw on either side.
