For purposes of this video, we are going to take an existing light switch and change it out with an INSTEON-Compatible switch. Now switches, dimmers, keypads and toggles will all wire the same way. We going to show how to install a compatible dimmer switch.
The first step is to remove a switch. Now we’re going to want to kill the power to this switch by shutting off the breaker or the closest disconnect means to this switch for our safety.
Now that the power is off, we’re going to remove the faceplate and start taking the switch out.
Now that the switch is out of the wall, go ahead and restore the power to it and use a voltmeter to determine which leg is your hot leg and which is your switch leg. Now in some cases, this is denoted by a different color: black being your hot or maybe red or blue or another color being your switch leg. We’re going to show you how to identify that in this case.
Placing one leg on one side of the terminal and the other onto the ground wire and I’m reading the voltage.
Now that we’ve identified which is the line and which is the load, you want to make sure that the power is back off on the switch because we’re going to flag one of these with a black tape or some other color so you know which leg is which. This one here with the meter reading is the line coming in.
Now that we’ve removed the existing switch, we are going to place a SwitchLinc Dimmer in its place.
We’ve identified our hot wire, our load wire, our ground wire and we also have a neutral wire, but we’ll talk about that later. Let’s get the switch installed now.
Now this switch wired up exactly wire for wire to the switch that I took out. The only difference being the neutral wire -- which is added. Now in this box, we have a neutral wire and I’ve actually added a small piece to lengthen it so I can work it outside the box. What we’re going to do and just attach that wire like this and this switch is ready to have the power turned back on. In the event that you don’t have a neutral wire in your house, you might want to contact an electrician to help you out with this.
Now just keep in mind that this neutral wire was not attached to the existing switch. This was a wire that just passed through the box, but was identified as a white wire.
One thing we want to do also when we’re making a connection: make sure the wire nut gets on nice and tight and also covers all the copper that was exposed. You can check this by tugging on them. Make sure they are nice and secure.
Now let’s the wires back into the box. We do that by pushing them in – just like this. Then we’re going to place the switch. Make sure all the wires are all tucked safely inside the box making sure the LED is also on the left side up at the top. Now it’s time to screw the switch into place.
Now all we do is finish screwing the switch. Put the face place back now. Now we’re ready to test the switch.
Now that power has been restored to the switch, let’s go ahead and test it. The light comes on, goes off and that’s it.
