Replacing Switches & Outlets

Introduction Install the Switch Box Attach the switch box to a wall stud. The typical height is 42″ from the floor to the bottom of the box. If multiple switches are used, gang the boxes together. Follow electrical code recommendations as to the box area required for the number of switches installed. Step 1 refer to wiring plan to determine wiring route drill holes for wiring Drill Holes for the Wiring Refer to your wiring plan Image 1 to determine the most efficient wiring route from fixture to fixture. A heavy duty right-angle drill makes it easier to work in tight spaces between the ceiling joists. This tool, called a Hole Hawg, is available at most rental centers. The 12 refers to the gauge, or thickness, of the individual wires, or conductors.

Trim the peeled insulation with wire cutters. Before stripping the cables that feed the overhead fixtures, install two-screw cable connectors Image 2 into the holes called knockouts, out of the boxes. These connectors serve not only to protect the wire, but also to hold them in place. For this particular box, prepare the ground wires for two switches by fitting a copper crimping sleeve over the three incoming ground wires plus two extra pieces of bare wire Image 3.

Tightly crimp all the wires together using a multi-function stripper Image 4. To form a good electrical bond, splice the wires by twisting them together with pliers Image 5.

It’s easy to identify a three-way switch because it has three screws (two brass and one dark). Pull the switch out and label the wire hooked to the dark “common” screw. Unhook the old switch and hook up the new one: ground wire pigtailed to the box, travelers to the light-colored screws (interchangeable), and most important, the labeled wire to.

How to Install a Light Fixture With Two Lead Wires Often, homeowners purchase a new interior or exterior light fixture, then pay a handyman or electrician to hook it up because the wires are different colors. Most light fixtures have two electrical wires with colored insulation and a copper ground wire. An enthusiastic homeowner can save the cost of a professional by knowing which wires connect to which.

With this knowledge, you or a family member can do the wiring connections for one or more lights. If the breakers aren’t labeled, ask a family member to turn on the light with the switch as you cycle through the breakers until it goes off. You’ll see white wires at one side of the switch and black wires attached at the other side. One of the black and white wires goes to the light fixture. The other black and white wires are the electrical circuit for the switch.

If the light can be turned on or off from switches at each side of the room, you’ll see a blue wire that connects the electrical circuits for three-way switches. In some cases, it may run through the electrical box where the existing light is installed, but it is only a switch wire and not a wire for the light.

Power to light — to switch — to switch Wiring a 3 way switch with the power coming in through the light and flowing to the switches. Be sure to mark the white wire as noted so if any future repairs or replacement is needed, whoever goes into the box will know it is marked as a hot wire. Power to light — to light — to switch — to switch Same scenario as option 5 but with multiple light fixtures.

The white wire coming from the second or last light will be marked “hot” with black electrical tape. This way, all the wires can be used with no waste.

Monday, November 12th, , Created: Saturday, January 26th, Can I put a dimmer switch on a three way hallway light? Can she do it? I know you like that kind of an answer. In fact I don’t think I was perfectly clear about this when I did the segment on the TV show, judging by the confusion I heard after it was broadcast.

A three-way switch does not just turn the electricity on and off, but it switches the current from one line to another. That is why the three-way switch has three screws on it. One is the common wire and the other two carry that common current to one line or another. In fact a three-way switch all by itself would be of little use for your light.

It takes a pair of three-way switches as shown in the diagram to cause that re-routing of electricity that will cause the light to change whatever state it is in, on or off, to the opposite state when you reverse either one of the toggle switches. If you simply replaced one of the three-way switches with an ordinary dimmer switch, it would no longer toggle from one line to another and would only go on or off and reduce the power of the current. The top of the stairway, bottom of the stairway reversing control would no longer work.

You can however now find 3-way dimmer switches in the stores which have three wires out the back, like the three screws on the regular 3-way toggle switches, and that would replace one of the 3-way switches. A year after I wrote this page, Lutron showed me Multiple dimmer controls that can have up to 10 dimmer switches for a single light!

Most modern switches have screw terminals on each side and may also have holes in the back to accept the end of the wire. You can easily loosen the screws on the side of the device with a standard screwdriver turning counterclockwise , but you may find getting the wires out of the back of the device tricky. To remove these wires, insert the blade of a small screwdriver into the slot under the hole into which the wire is inserted and push in as you pull the wire loose.

Aug 19,  · Three-way switch wiring is more complicated and will require a timer that is specifically for three-way switches. Luckily, most things that you would want to put a timer on, like a porch light, only have one switch controlling them.

View Stubbie’s Album Quote: See the part that confuses me most is that i installed one of these fans with just a single switch and it works flawless, but i do know that regardless of whether the remote is there or not, if you hit the switch up to on the light turns right on. Putting it on a three way will not change the way it operates. You just have two places to turn it off and on. But what KBsparky says needs to be considered. You only have a black and white so switches basically turn power off to the fixture or turn power on to the fixture.

With a switch ‘off’ you have no power so the remote will not work anything. From what you have said if you turn the switch off then come back later and turn it on the light will come on regardless of the remote. So I would say there is some default that allows that to happen when power is turned off with the switch. A 3 way won’t change that but as Kbsparky has said it really isn’t meant to be installed that way.

I installed a Hunter remote ceiling fan about a month ago and it sounds pretty much to have the same operation as yours. You had a black and white from the reciever that connected to incoming power.

So on to the installation which consists of a few simple steps: Headlight Wiring Harness Connection Note: The H4 style connector 3-wire 1. The connection shown in photo A supplies the control power to the two relays in the new harness. Just plug one of the stock faded yellow headlight connectors female H4 into the bright yellow mating connector male H4 on the new harness.

Multi-way switches (also known as “three-way” or “four-way” switches) are those that allow you to control a single light with more than one physical switch. These aren’t quite as simple to install, and actually require a subtle change to the wiring.

It’s not that hard You have 3 options: Use a factory switch. Use an aftermarket switch. Make your own switch system. Factory switchMost of you will have a hotrod that uses a steering column that has a turn signal switch built in. What you need to do is find the wiring diagram for the vehicle the column came from. Just find it on the internet. It will show you which wire should go where

Email Introduction Homeowners may choose to replace or upgrade a light switch for functional or for aesthetic reasons. Changing the light switch is a simple and inexpensive DIY project. Understanding how the switch is wired is the most important part. The bare or green-wrapped ground wires serve as a backup to divert the power safely away in case of an electrical fault. The white wires will be connected to each other but not to the switch itself; this connection is typically secured by a plastic wire nut.

The ground wires will be connected to each other and attached to the grounding screw on the switch. Step 1 Turn Off Power Turn off the power to the circuit at the circuit breaker or fuse box. You can double check to ensure that it was turned off by flipping the switch in an attempt to operate a light, and by using a voltage tester once the switch plate is removed to confirm that the wires are not charged. Step 2 Remove Switchplate and Switch Use a flathead screwdriver to remove the switch cover, and a Phillips head screwdriver to remove the existing switch from the box.

Step 3 Remove Wires From Old Switch Use a screw driver to loosen the screws holding the electrical wires on the side of the switch, and then disconnect the wires from the switch itself. Pay attention to the wire colors and where they had been attached on the old switch, as you will be duplicating their placement on the new switch. Using needle nose pliers will be helpful while working in this small space.

Keep the wires separated by bending them to opposite corners of the box. If the switch is grounded, remove the grounding wire last.
