The diagram below will give you a better understanding how this circuit is wired. Notice that there is a 3-conductor cable coming into the first box, then a 4-conductor cable going from left box to right box, then a 3-conductor cable going from the right box to the load. Now for wiring, lets assume you’re looking at the switch just like it shows. The lower left screw is the common and gets the black wire from the source 3-cond. The upper left screw gets the black wire from the right box 4-cond. The upper right screw gets the red wire from the right box 4-cond. The white wires tie together with a wire nut.

Installing a three-way dimmer switch on an existing 3-way switch circuit is not only a simple job, but it will add flexibility to your lighting design and improve the overall atmosphere of your living space. The primary thing that confuses most do-it-yourselfers is the fact that only one of the three-way switches needs to be replaced with the dimmer switch. So, your first step is to think about which of the two switches you use the most. This is the one that you should replace with the dimmer.
Turn off the power to the circuit. Remove the cover plate from the switch. Remove the two screws that secure the switch to the wall box and gently pull the switch out. Double check with a voltage tester that the power is off. Position the switch so that the side with the two screws is facing your right. Hold up the 3-way dimmer next to the existing 3-way switch in the same manner.
Remove the RED wire from the existing 3-way switch and connect it to the same place on the dimmer switch.

SO I’ve been wanting to add a dedicated circuit of super white LED’s under the hood, I’ve seen a bunch here and elsewhere so that’s nothing new, I want to have the power source connected to the posts underneath the terminals so that you can disconnect the battery cables and still have lighting under the hood. I was thinking of different contact switches and another member mentioned mercury tilt switches.
Intrigued I picked one up and started screwing around with it. It seems like a little bit more of a challenge and I don’t think I’ve ever seen anyone else do it. For those of you that don’t know what a mercury tilt switch is, it’s a tiny little glass cylinder with a drop of mercury and two electrical contacts inside one end of it.

You have to run a new wire to the other 3 way switch. The red tells the other one what position the other switch is in. Of course your switches have to be changed to 3 ways. It is unclear why you would ever have two blacks but only one white wire and where they might lead, and what exactly you’re trying to do. You could be adding danger to confusion unless you figure out exactly which wire does what. Any white wire used in 3-way traveler or switched must have its insulation taped over at both ends with black or red to show it is no longer to be considered neutral.
The only time you would have neutral between two 3-ways is if the light is between the two switches rather than the switches being connected directly to each other. What does red wire black wire and green wire denote? Red and black are the two separate V hot legs of a V 60Hz supply, green is the ground. White is the neutral. Answer only for UK wiring installed before and similar 50Hz household electricity supplies. Red is the V 50Hz hot, black is the neutral, green is the earth or ground.
Those colours became obsolete for use in the UK for all new wiring installations done since

Access the wiring Now it’s time to get at your wiring. There is often a pair of screws holding each faceplate in place, at the top and bottom. Unscrew these screws then remove the plates covering each switch. A common practice is to wrap switch terminals with electrical tape once their wires are connected. In my case, the old switches had exposed terminals so I made a mental note to tape them later. Just to be safe, use a voltage pen to check for a live current.

Power to light — to switch — to switch Wiring a 3 way switch with the power coming in through the light and flowing to the switches. Be sure to mark the white wire as noted so if any future repairs or replacement is needed, whoever goes into the box will know it is marked as a hot wire. Power to light — to light — to switch — to switch Same scenario as option 5 but with multiple light fixtures. The white wire coming from the second or last light will be marked “hot” with black electrical tape.
This way, all the wires can be used with no waste. Power to light — splits to switch and to light — light to switch This scenario gets a little tricky. Power to light — splits to two 3 way switches Here is another example of wiring a 3 way switch with the power coming from the fixture. I is similar to Option 3 only with the power coming into the light fixture. This option is helpful if you are adding a light to an existing building and it is easier to drop all the lines down from an attic instead of trying to get wiring up from a finished basement or trying to fish wire up two stories.
Power to switch — splits to switch and to light In this scenario the power comes into one of the 3 way switches.

Check with your insurance provider, and with your local electrical or building authority for any required permits or approvals that may be required.
A 3 wire cable that is routed between switch 1 and switch 2 – this wire cable comes with a black / red / white wire plus the bare equipment grounding wire. 4. Insulated wire nuts to connect / join wire together, variety of sizes out there so make sure you obtain the correct size.
Ask Question Step 1: Selecting Your Switch You need to decide if you want to purchase a switch or salvage one from something else. Make sure the switch you use can handle the amount of current you need Decide if you want an off position or not. Decide if you want a sliding switch, a toggle switch, rocker switch, or even a spring loaded switch that returns to off when released. If there is a junk car around, check it for power window switches or electric seat adjusters.
Both are most often DPDT switches. Don’t forget to steal the motors or sometimes linear actuators out of the seat adjusters, if you can!!!! Broken stereos commonly have one or two switches in them If you salvage a switch, the first thing I would do is test ACROSS the switch to be sure it is double pole.
The switch has two rows of contacts with three pins per row.

Considering p duplex receptacle, if I break the tab, can both receptacles supply 20 amps? The outlet configuration – the physical design of the holes – determines what can be plugged into it. As both “halves” are the same configuration, either one can provide 20 amps. You should note, however, that trying to pull 40 amps from one 20 amp circuit will absolutely trip the breaker. In wiring a switched half-hot outlet that gets Its power from the outlet box if the end of the white neutral wire is capped in the switch box, why can’t the end of that wire also be capped in the receptacle box?
Key Wiring Components: 3-Way Switches and Cable. Three-way switches are always installed in pairs to control a light from two locations. The switches have three hot screw terminals—one “common” and two “travelers”—and a grounding terminal.
Email Introduction Homeowners may choose to replace or upgrade a light switch for functional or for aesthetic reasons. Changing the light switch is a simple and inexpensive DIY project. Understanding how the switch is wired is the most important part. The bare or green-wrapped ground wires serve as a backup to divert the power safely away in case of an electrical fault.
The white wires will be connected to each other but not to the switch itself; this connection is typically secured by a plastic wire nut. The ground wires will be connected to each other and attached to the grounding screw on the switch. Step 1 Turn Off Power Turn off the power to the circuit at the circuit breaker or fuse box. You can double check to ensure that it was turned off by flipping the switch in an attempt to operate a light, and by using a voltage tester once the switch plate is removed to confirm that the wires are not charged.
Step 2 Remove Switchplate and Switch Use a flathead screwdriver to remove the switch cover, and a Phillips head screwdriver to remove the existing switch from the box. Step 3 Remove Wires From Old Switch Use a screw driver to loosen the screws holding the electrical wires on the side of the switch, and then disconnect the wires from the switch itself.
Pay attention to the wire colors and where they had been attached on the old switch, as you will be duplicating their placement on the new switch. Using needle nose pliers will be helpful while working in this small space. Keep the wires separated by bending them to opposite corners of the box.
