General knowledge on wire colors will come in handy during minor electrical emergencies such as changing an overhead light fixture, replacing a wall light, or installing new bulbs, lamps, and switches. Wires are color-coded to avoid wiring errors that may lead to accidents and electrical inconvenience to household, the whole block, or—in some cases—the town. Black Wires Black wires are specifically used for hot wires and voltage transmissions. Most of these wires are utilized as switch legs and may feed an outlet as well. You should not use these wires for a ground or neutral connection. Red Wires Red wires are second to black wires when used as hot wires and switch legs for volt installations.
Electrical Outlet Is Wired Backwards
Typically, a black wire, a white wire and a ground come from the breaker or fuse panel to the first switch. The black is usually ‘hot’, the white is ‘return’. From the first switch to the second switch, you have black, red, white and ground. The black wire and the red wire take turns being ‘hot’, depending on the position of switch 1.
White is still ‘return’, and ground is ground.
Jun 23, · Since you have no way of determining which wire is ‘hot’ at switch 2, you can’t hook up your receptacle as ‘always on’ there. You could tie it to the light though, so when the light is Status: Resolved.
A brand new GFI comes from the factory in a tripped state and cannot be reset till it is hooked up right and power turned on. They are under the impression that the outlets there are not already protected. This may not be true. It doesn’t actually hurt to double-protect, but it can get confusing. For instance, if something at the bathroom outlet tripped a GFCI, it might trip the device that had been added right there as an “upgrade,” or else it might trip the original one in the garage — whichever one happened to respond more quickly.
If you don’t know the complication, you won’t be looking in the right place to restore power. Besides having to hook a GFI up correctly, anytime you introduce GFI protection onto existing wiring and existing loads, you may find unexpected tripping. Although this could be detecting a shock hazard you weren’t aware of before, there are also a few wiring conditions from the past that are not GFCI friendly.
One unintentional condition would be where a ground wire is contacting the neutral side of a receptacle. Some intentional conditions would include places where the neutrals of two circuits are unnecessarily and improperly combined in a multi-gang box, or where the neutral for lights of a GFCI-protected 3-way switch system is introduced from somewhere ahead of the GFI you put in.
Tripped or just dead? If a ground-fault interrupter is giving trouble, can you tell the difference between its re tripping and its simply failing to reset? The reset buttons of newer GFIs from on will purposely not catch hold if they are not receiving power or are not hooked up right.
Hooking up a combination switch with outlet and another switch
So where do the wires go: And what if there is no ground wire? On a conventional volt “two pronged” electrical outlet that accepts grounded plugs two prongs plus the rounded center ground connector prong , your circuit will have three wires: You can see our white neutral wire connected to a silver screw on the receptacle in our photo. You will see the hot black wire connected to the bronze or darker-colored screw on the receptacle shown at below right.
The receptacle we used for these photos happens to be a A rated device that permits the wire to be inserted straight into a clamp that is tightened against the wire by the screw.
Alternate 3-Way Switch Wiring Diagram 1, NMLine voltage enters the light fixture outlet box. No longer allowed after NEC (if no neutral wire in switch boxes) Alternate 3-Way Switch Wiring Diagram 2, NMLine voltage enters the first 3-way switch outlet box, light fixture is located between switch longer allowed after NEC (if no neutral wire in switch boxes).
You guys have always helped me with anything else I’ve asked. Since we are in an apartment, it’s simply mounted on the ceiling, but as there is no ceiling light outlet, I am using this: The wall outlet has a switch on my wall that controls it, on and off. It only controls ONE of the 2 plugs on the wall, which is where I have the track light plugged in of course.
I got to thinking that I would like to change that switch to a dimmer switch to dim the lights when needed. So like I mentioned about, I want to know if this is even really possible? When I googled what I want to do, the only hit of note I got was saying to not install a dimmer on a switch that controls an outlet. The example they gave was because it can blow certain things you plug into it if the switch isn’t at full, like say a Vacuum.
In my case though that switched outlet will only EVER have my light plugged into it and it’s not even an easily accessable plug, it being behind my desk which is a beast.
How to Wire a Switch Outlet Combo Circuit
Most of the outlets in your home are of the duplex variety—that is, you can plug two devices into them at one time. A half-hot or switched outlet is a duplex outlet that has one half permanently “on” or ready to provide electricity while the other half can be turned off and an via an ordinary wall switch. While the entire duplex outlet could be turned on via a wall switch, only one of the two plug-ins is usually switched; this leaves the other half permanently powered for other uses.
This kind of outlet is quite common in modern construction. If you plug a lamp into the switched side, you can turn the light off and on via the wall switch.
Hook-up boxes are available with single amp and single amp outlets, and with multiple outlets, featuring a amp outlet served by a amp breaker, a amp outlet served by a amp breaker and a number of amp outlets served by a amp breakers.
Before trying to hook up your player, make sure it is plugged in and turns on when you press the “power” button. Usually a small light or welcome message appears when the DVD player is working correctly. There are at three common ways to connect a DVD player, and each needs a different cable to work. Your DVD player should come with all of the appropriate cords, but you need to check which connections your TV accepts as well.
The three most common are. HDMI connections are the highest quality connections and you only need one cord for both the audio and video. There are three prongs at either end– red, yellow, and white — and they match up to corresponding colored inputs on both the TV and DVD player. Once you know what connection you will use, locate the cable and make sure it is not torn or frayed.
If you need a new cable, or are missing one, take a picture of the input you want and bring it to your local electronics store to find a replacement. If possible, use and HDMI cable, as they are the easiest to install and have the best quality video. Once you know what connection you will need, make sure you put the DVD player close enough to the TV so that you can reach the appropriate cables to the back.
Do not stack different electronic equipment on top of one another — they can quickly heat up when in use and damage the electronics. This prevents the likelihood of electric shocks and protects the equipment.

Wire An Outlet How to wire an outlet. Standard outlets are known as duplex receptacles. There are a few options to choose from when you wire an outlet. Most are wired so they are hot at all times but some are wired so they are switched off and on. You can also wire outlets so that only the top or bottom receptacle is hot at all times and the other is switched. To wire an outlet to be hot at all times or both receptacles to be switched requires a 3-wire cable.
To wire an outlet so that only the top or bottom receptacle is switched and the other receptacle remains hot all the time, requires a 4 wire cable. You need to know up front which scenario you prefer if your wiring a new circuit. If you are just replacing an old outlet with a new one then the instructions on this page will help you identify which scenario you are dealing with based on the number of wires that are connected to your old outlet.
