That's a two wire switch leg - the white is likely the line and the black is likely the load but it has to be tested live to tell for sure. The socket is used with a three way bulb containing 2 separate elements that are energized separately and then together as the switch knob is turned for varying degrees of light. Note - the Neutral is not connected to the actual switch, the two Neutrals are connected together using a connector block. As someone else already mentioned this is a switch leg. I'm moving a light switch to a different wall and have found that the cable from the switch to the light has 3 wires but I don't know why. You'll often see us refer to 2-wire and 3-wire lighting systems. This is why most of the so call 2-wire smart switch in the market is not really 2-wire ready, unless you are still using incandescent lamp at your home. For a smart tips, you are highly recommended to check the capability of supporting low power LED bulb when you are choosing an electronic switch which can be used with 2-wire (no neutral wire) installation. After reading where the red wire goes in a light fixture, someone asked me where to connect the red wire to a light switch. The source is at SW1 and 2-wire cable runs from there to the fixtures. When I opened the outlet box, the switch was connected to two black wires. New comments cannot be posted and votes cannot be cast, More posts from the homeautomation community. Note wirees 1 and 2 should always have power. 4: Neutral wire. Google "GE 45606" and you should find what you're looking for. There will be an additional wire needed (often red) to connect the switches together to a dedicated screw or input on the switch that is specifically marked for this purpose. An example of a 3-wire lighting circuit is shown in Figure 2. Multiple Light Wiring Diagram. Hope this helps. Always turn off the power at the breaker or fuse box before you work on electricity. I'll take a moment to outline each wire, it's typical color, and it's use (HUGE DISCLAIMER - YOUR WIRING MAY VARY!!! Use a switch that does not require a neutral, like Lutron Caseta. The brown wire is Live (also know as permanent live), this brings the live supply to the switch. Press J to jump to the feed. Comes in from somewhere, goes two other places, one being the light fixture. Traveler - this comes in on multi-way switches. 2: Hot wire to your switch. The new switch has 4 wires: black, red, red/white striped, and green. As I have already mentioned in the introduction paragraph, a two way switch is very useful in staircase lighting as you can turn on the light just before you start to climb the stairs and once you reach upstairs, you can turn off the light simply by toggling the switch placed near the top of the staircase. Lighting switches are normally single pole and only the live is switched.. Is it not acceptable to drain this onto ground instead? The instructions for these will say they only work with incandescent/halogen bulbs, but my experience has shown that they do work with some newer generation dimmable LED bulbs, even single ones. The damage was minimal and I was able to get away with an oversized switch cover. I have one in my kitchen and it scared me for years. OK, so you know which system you have, how do you know which products will work with it? Each product that can be used in a lighting system has an icon so that you can quickly see which system it is designed to work in. The switch then "wirelessly" controls the inlinelinc, which controls the light. The two black wires were attached to the wires coming out of the wall and the green wire was attached to nothing. If You Want the Switch to Control Both the Light and the Outlet. With the power coming to the switch and then going to the lights, you will notice that there are two black wires, two white wires and two ground wires (bare wires). got links/info to the insteon, smartthings bridge setup you have please? If so you MAY have a 3-wire system, but you should confirm this with a voltage meter or consult a qualified electrician. Or call in an electrician and have the circuit re-run with 14-3 wire, so there's a black, white, and red, and then red becomes your load. Notice the black wire is the only wire that we are controlling through the 2-way switch. Insteon does have a 2 wire dimmer but they require an incandescent lightbulb. The brown wire is Live (also know as permanent live), this brings the live supply to the switch. See my post elsewhere in this thread. If not, you'll have to use Lutron's hub in conjunction with your main smart hub if they are capable of communicating with each other. The ground wire is designed to protect you. Copyright 2021 Vesternet All Rights Reserved. The first time I saw a red wire on a light switch, it certainly confused me. The blue wire is known as the Switched Live and takes power to the light. When you see a red wire in a light switch box, it can mean two things. Do all the wires have a brown sleeve on them? Are you just playing a semantics game with the neutral wire? Can I attach the new switch somehow? If you have a 2-gang or 3-gang switch you may have black and grey wires, however these will have a brown sleeve on them as they are also switched live wires. Both Leviton and Cooper have z-wave dimmers that don't need a neutral. Wire nutted together in the back of the box. Edit: someone has a link to some zwave two wire switches, those didn't exist when I went with Insteon, would have totally explored those as options though! That’s the only purpose the ground wire … First of all we should connect the ground wires to the box. If you want the switch to control the … GE makes a 2 wire smart switch with a model number of 45606. ;). This is the wire that goes up to your light fixture. The switch in question is a single pole. A three-way light switch is one where you have two switches that have the ability to control the same light or set of lights. This is a wiring diagram for a standard 3-way lamp switch. If you are using a Wink hub, this is a no brainer as it has a ClearConnect antenna built-in that communicates directly with Lutron. This will allow you to connect the first light as you described above, and to run this additional light from the same switch by utilizing the red conductor in the 3-wire as the “switched” conductor, and the black wire as the continuous hot wire. 2) You existing switch has 1 wire (hot) to feed the switch from the circuit. There are a couple of ways in which you can make a two-way switch connection. Pull the wires apart to release the fixture and set it aside. Sensors, switches, cameras, locks, etc. I chose Insteon as my two wire solution and it's been rock solid. The 3-wire system is less common than the 2-wire system, it includes a Neutral at the switch as well as the Live and Switched Live wires. The Insteon app is garbage, so don't count on that to run the show. White is generally the line at a switch. If you're using a Z-wave switch you need a neutral line to tap off of in the switch box so you can power the Z-wave functionality of the switch with the light off. A standard 2-wire lighting circuit is shown in Figure 1. Clip off the bare wire loops on the ends of the wires in the switch box with the cutting tip of a pair of … I guess it wasn't clear I was talking about connections TO THE SWITCH here. Is that a dimmer switch? While a standard switch DOES in-fact only have two wires connected to it (plus ground) things can get a bit more complicated with a smart-switch or multi-way switches. Two-way switches are single pole single throw (SPST) with two connection wires and are wired with 12/2 or 14/2 cable between the switch and fixture. After making sure the power is off, you strip the black wire in the two-conductor cable (which also has a ground wire) and make a pigtail with two 6-inch lengths of black wire salvaged from a spare piece of cable of the same wire gauge. However, the third wire, which typically has a green/yellow sleeve is the Earth wire. ): Line - this comes from the panel and is your "hot" wire. NEC 404.2c requires a neutral at switch boxes. Switched Live is only live when the switch is on (this is where it gets its name from). Any automation questions/discussions are welcome! If the answer is YES to either of these points, you have a 2-wire system. Typically it's black. Works in a 3-wire system, a Neutral is required (full information above). Test to verify. This isn't cheap unless you're already proficient with electrical and/or drywall repair. If you have something like Lutron Caseta, then it will work. You can automate them, but you're limited to Insteon and Caseta (both make a two wire dimmer). Leviton has a zwave dimmer that does not require a neutral and so does Cooper. It's been discontinued for quite a while AFAIK. Insteon also has a native Echo intergration. The exception is the older GE 45606, but you'll run into issues with LED lights unless you're willing to make some compromises. A 2-wire system includes two wires - Live and Switched Live. SmartThings compatibility will be available in the near future. (assuming it is a steel box). Typically white. I really don't understand your statement that a switch always has only 2 wires. Some random Internet stranger doesn't know how every house is wired. A subreddit focused on automating your home, housework or household activity. I've heard that some Lutron switches don't need a neutral wire (which it appears you lack here). Agreed. https://s-media-cache-ak0.pinimg.com/564x/29/f2/e7/29f2e74dbddace17a9e20e0d4255d4ff.jpg. Connect the light fixtures by wiring their black wires to the black cable wire, their white wires to the … Two white wires were attached to each other. 3: Switched hot wire. Firstly, what do we mean by 2-wire and 3-wire systems. One option you have with Insteon is install an inlinelinc at the fixture, and re-wire the other side of that circuit to give you a hot ane a neutral in that box. http://www.leviton.com/OA_HTML/ProductDetail.jsp?partnumber=VRI06-1LZ§ion=67552&minisite=10251, http://www.cooperindustries.com/content/public/en/wiring_devices/products/lighting_controls/aspire_rf_wireless/dimmers/aspire_rf_600w_incandescent_smart_dimmer_rf9534.html. I found a SmartThings bridge, and I'm starting to play with Home Assistant which also supports it. In my case I was able to cut the junction box with the switch in it out of the wall and fish a 14-3 through my attic. Load - goes to the load (such as a light). By using our Services or clicking I agree, you agree to our use of cookies. Note - the switched live has a brown sleeve on it, this highlights that the wire is actually a live wire, even though it is blue, this ensure that it is not confused with a neutral wire. That’s a good question. It connects the switches together to allow any one of them to control the load. Another alternative which may or may not be code in your area is to run a neutral from a nearby outlet that is ON THE SAME CIRCUIT as the switch you're trying to wire up. Really though what switch did you get? As the 2-wire system is the most common, it's probably best to start with the assumption that you have a 2-wire system, especially if you're in the UK or if your house is more than 3-5 years old. The switch does work with this configuration. The Earth is a very important part of the electrical system and all switches, appliances and lights must be correctly earthed. Or could it be a dimmer? 5: Ground wire… You could alternatively just run a single wire from the light instead. Most light fixtures have two electrical wires with colored insulation and a copper ground wire. At least in new wiring that's how it works. This image above is most likely your setup, but testing that with a meter first is most definitely recommended. The hot and neutral terminals on each fixture are spliced with a pigtail to the circuit wires which then continue on to the next light. Neutral - not connected to the switch. In your case, judging by the fact that the second wire is white I'm assuming that's coming from the load something like this: https://s-media-cache-ak0.pinimg.com/564x/29/f2/e7/29f2e74dbddace17a9e20e0d4255d4ff.jpg, In that case the white is actually the line, then the black is the load. Usually, a twin red cable implies a switch wire, consisting of a permanent live, and a switch return wire. Remove the Three-Way Switch From the Circuit Start with the three-way switch that will be removed. You can double … Perhaps switching out your smart switch would be your best option. Figure 1: A standard 2-wire lighting System. In the event that the live wire comes loose and touches the light fixture, the ground wire diverts the power and blows the breaker, instead of you feeling an electrical shock when you touch the fixture. Untwist the connectors holding the two black wires and the two white wires together. If the light switch has a ground screw on it (usually green and at the bottom of the switch), connect it now. To wire this circuit in this manner, you will need to run a #14/3 between the two light boxes. This is an important point as many products, such as relays, cannot work if installed into a 2-wire system. But for the sake of simplicity we ignore the Earth wire when explaining wiring as it plays no active role in the day-to-day workings of your light circuits. This is the most common lighting system in Europe, almost all homes use this system, especially in the UK and Nordic regions. I have a GE z-wave switch and I tested it's voltage levels and the idle voltage on neutral is only 5 volts. Turn Off Power. HOWEVER, this really needs confirmed with a meter. You have an incoming hot wire (black) going to one screw (it does not matter if you use the brass or silver screw) on the side of the 2-way switch and a black wire from the other screw on the 2-way switch going to the load (light, ceiling fan etc..). 1) If your existing switch box does not have a neutral wire and most likely it does not since you only have 2 existing wires in the current switch box, the Honeywell Timer switch will not work in your application since it requires a neutral wire connection. I'm sure it's still up to code to do that in many places today. A standard 2-wire lighting circuit is shown in Figure 1. Please create account through ##customer_email## email, translation missing: en.general.accessibility.skip_to_content, APNT-1: Installing a Fibaro Dimmer module in a Wall Switch, APNT-2: 2-way Lighting Using Fibaro Dimmer Modules, APNT-4: 2-way Lighting Using LightwaveRF Dimmers. Turn off the power to the circuit at the circuit breaker or fuse box. Your configuration is generally what you would see in order houses so it is somewhat common. A single-pole, single-throw switch — such as a light switch — works by interrupting the hot wire, so it has two brass terminals for the hot connections and no silver terminals for neutral. Do you have two blue, black or grey wires going to a connector block? Ground - should be connected to the switch and the box (if metal). of insulation … I have a really old house and it was FULL of two wire dimmer switches. Power controlled by this switch. Load - this goes to the load (such as a light) and is also typically black. There is no neutral in this setup as it's in a junction box somewhere (likely in the light source). The 2 wire source feeds to an adjacent switch for a different light which then feeds this switch with 2 wires. Switched Live is only live when the switch is on (this is where it gets its name from). One '2-Core + Earth' cable takes Live and Neutral to the switch back box, a second cable takes the Neutral and Switched Live to the light. Strip New Wire Ends. Built in 1961 if that makes a difference. While a standard switch DOES in-fact only have two wires connected to it (plus ground) things can get a bit more complicated with a smart-switch or multi-way switches. Click to expand... No, there are no other wires present, each cable for each light is simply twin and earth, and it is just this one cable in question, which is two reds and earth. Typically either bare copper or green. We've tried to make this as easy as we can. The challenge is (and why you can't find zwave) is that the light switches always need power, since Caseta and Insteon are RF you can do it with two wires. Strip 3/8 in. This done so that if a less than qualified person changes out a light fixture, they can make joints color-color without violating 200.10c. That's just how it was done then. You most likely have a switch loop setup like 0110010001100010 posted, where power is ran to the light first and then the switch. So all newer buildings should have a minimum of 4 wires at a switch. This keeps you safe from potential electric shock. The term is slightly confusing as the system will actually include three wires. Typically red. Where I live that white wire should have been wrapped with black tape to signify that it's also a hot wire and not a neutral like white normally is. I'll take a moment to outline each wire, it's typical color, and it's use (HUGE DISCLAIMER - YOUR WIRING MAY VARY!!! Figure 2: One example of a 3-wire lighting System. Wiring a 3 Way Lamp Socket Switch. Most require a neutral which you don't have. ): Line - this comes from the panel and is your "hot" wire.
