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. Wiring a 3 Way Lamp Socket Switch. Usually, a twin red cable implies a switch wire, consisting of a permanent live, and a switch return wire. Strip 3/8 in. The ground wire is designed to protect you. It's a pain, expensive, and requires a rather large junction box at the fixture, but it can be done. (assuming it is a steel box). As the diagram at Electrical 101 shows, the line cable is all you need to supply power to a pair of switches in a single electrical box. 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. 2) You existing switch has 1 wire (hot) to feed the switch from the circuit. 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. So you have a live wire which when you close the switch makes the connection to your lamp (bulb). 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. I have always attached one black and one white wire to fans, lights, etc and this had me puzzled. 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. 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. This is the wire that goes up to your light fixture. You'll often see us refer to 2-wire and 3-wire lighting systems. 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. Two white wires were attached to each other. 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. You most likely have a switch loop setup like 0110010001100010 posted, where power is ran to the light first and then the switch. You can view your wishlist by creating or login account. 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. Google "GE 45606" and you should find what you're looking for. I'll take a moment to outline each wire, it's typical color, and it's use (HUGE DISCLAIMER - YOUR WIRING MAY VARY!!!

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. 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. 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. Hope this helps. Really though what switch did you get? 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. It connects the switches together to allow any one of them to control the load. So all newer buildings should have a minimum of 4 wires at a switch. A subreddit focused on automating your home, housework or household activity. Figure 2: One example of a 3-wire lighting System. 4: Neutral wire. Do you have two blue, black or grey wires going to a connector block? 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. Switched Live is only live when the switch is on (this is where it gets its name from). However, the third wire, which typically has a green/yellow sleeve is the Earth wire. If you want to keep the Z-wave switch, you need to run a neutral by replacing the 14/2 romex with 14/3 romex from the light, which will get you a neutral at the switch box. Typically red. The term is slightly confusing as the system will actually include three wires. 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. Are you just playing a semantics game with the neutral wire? Both Leviton and Cooper have z-wave dimmers that don't need a neutral. I chose Insteon as my two wire solution and it's been rock solid. Traveler - this comes in on multi-way switches. I have a really old house and it was FULL of two wire dimmer switches. That’s a good question. A standard 2-wire lighting circuit is shown in Figure 1. Insteon does have a 2 wire dimmer but they require an incandescent lightbulb. It's been discontinued for quite a while AFAIK. See my post elsewhere in this thread. That's just how it was done then. Connect the light fixtures by wiring their black wires to the black cable wire, their white wires to the … 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.

Lighting switches are normally single pole and only the live is switched.. 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).

The simple explanation is that a 2-wire system does not include a Neutral wire at the light switch, the 3-wire system does include the Neutral at the switch. HOWEVER, this really needs confirmed with a meter. Clip off the bent end of each wire with the wire cutter. 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. Some random Internet stranger doesn't know how every house is wired. This is an important point as many products, such as relays, cannot work if installed into a 2-wire system. 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. The old switch had 3 wires: 2 black and one green. Insteon also has a native Echo intergration. The first time I saw a red wire on a light switch, it certainly confused me. Perhaps switching out your smart switch would be your best option. If the light switch has a ground screw on it (usually green and at the bottom of the switch), connect it now. Any automation questions/discussions are welcome! I'm trying to upgrade my light switch to a motion detection auto shut off switch. Connect the wires on your smart light switch to the wires inside your wall. First up, a switch only ever has two wires (minus the ground) unless it's a multi-way. Note - the Neutral is not connected to the actual switch, the two Neutrals are connected together using a connector block. Typically either bare copper or green. Connect the in wire to the … 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. A standard 2-wire lighting circuit is shown in Figure 1.

The 2 wire source feeds to an adjacent switch for a different light which then feeds this switch with 2 wires. This is a wiring diagram for a standard 3-way lamp switch. There is no neutral in this setup as it's in a junction box somewhere (likely in the light source). Multiple Light Wiring Diagram. To wire this circuit in this manner, you will need to run a #14/3 between the two light boxes. New comments cannot be posted and votes cannot be cast, More posts from the homeautomation community. 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. I'll take a moment to outline each wire, it's typical color, and it's use (HUGE DISCLAIMER - YOUR WIRING MAY VARY!!! I have one in my kitchen and it scared me for years.
