How to you install a Leviton Slide Dimmer with Preset No. IPI06 to a double switch box where one switch controls the ligth fixture over the table(the one I want to connect the dimmer to) and the secon
Hi Velie, I am an electrician and can help you wire this switch. If I understand correctly, you have a two-gang switch box in the wall. In it, you have two switches installed. One switch is a 3-way type, and is one of two (or more) switches used to control preparation area lighting. The other switch is a single pole type and controls a light over your kitchen table. Right?If this is correct, remove the double switch wall plate. Let's set aside concerns with the 3-way switch. We have nothing to do to this switch so we will not need to remove it from the box, nor will we need to disconnect it. It works independently of the switch that controls the light over the table.Remove the switch that operates the light over the table. If it is indeed a single pole switch, it will have just two terminals for wires to connect. It will probably also have indications for ON and OFF on the handle. If installed correctly, flipping the toggle up or pressing the top of the switch will turn the light on. If is a 3-way switch, it will have terminals for 3 wires to connect. One of the terminals will be a dark color from the other two. Additionally, no ON and OFF markings are on the switch handle and the light may turn on in either handle position (depending on the position of other switches controlling the light). With this information, I assume that you have now verified that it is in fact, a single pole switch. Right?If all is going as expected, then we can continue. Shut off the power. Since a single pole switch has only two wires to connect, this should be fairly easy to do. One terminal should have a single wire that goes to the light over the table. The other terminal should have a wire that is powered all the time. It is very possible that the wire that connects to this terminal is ALSO is connected to the the 3-way switch either directly, or by a short length of wire that has a wirenut to connect several wires together. If you need to verify a connection to the 3-way switch, remove the switch from the box if needed (do NOT disconnect any wires). The wire should be connected to the dark colored terminal screw of the 3-way switch. This would indicate that this wire - and those connected by wire nut to it - is the source of constant power. Carefully fold the wires into the box and re-secure the 3-way switch if you pulled it from the box. You new switch has a single RED wire and TWO black wires. Twist a wirenut cap on ONE of the black wires (it does not matter which). Remove the wire that was determined to be powered all the time (was also connected to the 3-way's dark colored terminal) from the old switch, and twist it around the dimmer switch's remaining BLACK wire with a wirenut. Disconnect the remaining wire from the old switch and twist it around the dimmer switch's RED wire with a wirenut. Add the dimmer switch's GREEN wire in to the bundle of uninsulated ground wires in the wirenut inside the box. Fold all the wires gently into the box and secure the dimmer to the box. Install the wall plate and turn on the power. I hope this helped & good luck!
