Not incompatible. Normal wiring is three wires - black, white, and copper. The black is the "hot" wire, the white is the neutral, and the copper is the ground. When you put a switch in a circuit you now have 6 wires - three coming in and three going out. Since the switch cuts the power on and off, there will be a black wire coming into the switch and a black wire leaving. The whites are normally just connected together with a wire nut and the coppers are connected together with a wire nut or grounded to a metal junction box. So the new switch has four wires. Follow the directions. The white gets connected to the other two whites, The black gets connected to the incoming black. The blue gets connected to the outgoing black, The ground (green?) gets connected to the other two coppers or just taped off. Follow the directions. It is important to connect the switch's black wire to the INCOMING house black so that the switch has power to run the circuitry in the switch. Hope that helps. If you don't understand, call an electrician.
Sorry, there was a problem. Please try again later.I have suitiation with 4 black wires on 3 switches all 4 whites tied together and all black wires hot. When checked with voltage meter only ground reading 24 volt with neutral or black wire
Sorry, there was a problem. Please try again later.White is common Black is hot Blue is load or to the light Green is ground If you don't have a common, white wire, in the switch box, and most do not, you will have to pull in a common from another box.
Sorry, there was a problem. Please try again later.Most older homes only have 2 wires, so this won't work for that unless you rewire your switch/light. Most newer homes have at least a 3rd wire which is all you need. The ground wire isn't required. Lutron makes a switch where you don't need a neutral wire, but that's really your only option, except for using smart bulbs. So, you either have 2 or 3 wires connected to your current switch. If you have 2 wires (typically black and white), you either rewire or use another option. If you have 3 wires and one is a ground (typically black, white and yellow/green), then you are still out of luck. If you have 3 wires and one isn't a ground but is a neutral (typically black, red/black and white), then you'll be fine without a ground. I through in some recommended products for situations where you don't want to rewire.
I would recommend:
Sorry, there was a problem. Please try again later.Line (hot) Load Neutral Ground A normal switch opens and closes the hot, and neutral is not used. But a switch is not a powered device. This switch is a powered device, so it needs hot and neutral to power itself. It switches hot to load when engaged. Ground is simply ground.
Sorry, there was a problem. Please try again later.It's a device that requires power, even when the switch is off. You can't get this power from the switch wire because any current would need to complete the circuit with the light. So you could never really turn the light off. Fortunately if your house was wired properly, there is going to be a wire in the switch-box for the hot side of the circuit, You need to connect there to have an always on circuit to power the switches electronics.
Sorry, there was a problem. Please try again later.How do i wire 4 wires coming out of the wall to my range that has 3 wires
Sorry, there was a problem. Please try again later.1. Live wire (power source) 2. Live wire (supply to light) 3. Ground 4. Neutral
Sorry, there was a problem. Please try again later.Four wires, Yes. These "smart" switches require a neutral unlike traditional light switches. You must have a neutral wire in the box where these will be mounted. If your house is not too ancient, there should be neutral wires in the box connected together. (White wires)
Sorry, there was a problem. Please try again later.Have red, black, white and green. Black are tied together and not on switch. Reds power switch. Can nit get dinnercti wirj other two switches nor dim.
