I would have to say wiring a light switch is one of the most basic wiring projects in your home. Splice the white or neutral wires together. All ground wires bare copper are all now connected incoming ground, load ground and switch ground.
In this picture, you can see the strip gauge on the back of the switch. This simple step-by-step guide will show you everything you need to know, so let's get started! Motion lights have black, white and red wires. Now a typical circuit will contain a known as romex. This is achieved by connecting the fixed earth wire to the earth terminal on the socket or switch and then connecting a short length of wire from this terminal to the earth terminal in the wall box. Also, if you are not experienced at working with electricity, seeking the help of a qualified electrician is sensible. The new light switch and old ones are just not looking the same.
First of all we should connect the ground wires to the box. I'm talking just your normal run-of-the-mill switch. Once you have connected the hot feed, the black and red wires that are connected to the light need to be attached to the other side of the double switch. The device or outlet box must be connected to the ground wire if it is a metal box and to a plastic device box if there is a ground screw and grounding strap as an integral part of the box. Step 4 - Prepare Short Wire Pieces Locate the two short pieces of insulated electrical wire that you prepared earlier. You should only have two wires connected to the main switch terminals; one being a white wire identified by black tape or marked with a black felt pen to one terminal, and one black wire connected to the other terminal. William Machin began work in construction at the age of 15, while still in high school.
The 4-way switch is used in combinations with two 3-way switches when one or more lights are to be controlled from three or more locations. Simply strip the wire to the length specified and push the wire into the hole. The electricity flows from the hot wire black through the 2-way switch shown in off position and then to the light and returns through the neutral wire white. Mark the white wire with a piece of electrical tape to indicate that the wire is now a hot wire. Connect your ground to the switch ground terminal and the box if it is metal. If the switch operates correctly, turn off the power and finish switch installation by securing the metal switch tabs with their mounting screws to the electrical box. Repeat the steps and keep testing the new switch light until you have a fully functioning light.
Take off the cover, and note the color of the wire insulation for the wires that connect to each side of the switch. The number of insulated wires and bare copper ground wires entering and leaving the box will determine which of the three switch types you will need to install. Steps for Wiring a Single Pole Light Switch There are two basic wiring configurations for installation of a single pole light switch. Add up the wattage of all the bulbs in the fixture to determine the maximum wattage required. It is important to note that electrical codes change, and that in some areas local electrical codes are not the same as the National Electrical code.
This site is merely a collection of how some people do home improvements. Once you have done that for both wires coming out of the box, you will see two black wires, two white wires, and two bare copper wires. When purchasing the switch, be sure it is a double pole versus a single pole switch. Wiring a 2-Way Switch How to wire a 2 way switch. Do not connect this switch directly to a ring circuit. If you are installing a ceiling fan you will need a.
The white wires are wire nutted together so they can continue the circuit. Check the wires in the device box with the non-contact voltage detector. Use the needle-nose pliers to create a hook in the piece of bare copper wire that will be used to ground the new double outlet as well. That configuration is the one that will be explained in detail here. Remember to ensure a tight connection.
Connect the 6-inch length of wire to the green ground terminal. Whichever light switch project you need done, if you are unsure or uncomfortable about handling a wiring project, the better course is to hire a pro that will ensure that the job is done correctly. The third type of switch you may encounter in the home is the four way switch. Switches shall not be installed whithin wet locations in a tub or shower spaces, unless installed as part of a listed tub or shower assembly. The double pole or 2-pole switch is essentially two single pole switches operated by one toggle. Step 4 — Voltage Detector Use the voltage detector to check that there is no electricity running through the wires.
Step 6 - Mount Receptacles and Cover Now that the wiring to the receptacles is complete, install the wires on the mounting plates in the junction box. The 1-pole light switch will have two terminals on it, and possibly a third terminal that is a ground connection. The neutral wires are usually white and connect to the silver screw on the side of the switch. We're going to replace it with a non-pull-chain type of light and we want a switch where the kids can reach. First, twist the two bare copper ground wires together.
If the light switch has a ground screw on it usually green and at the bottom of the switch , connect it now. Remove the front cover of the switch and hold it in position where you want it to be mounted. There are certain spaces within a house that that are wired with a double switch light. Would it be permissible to run a switch loop from the light into the 2-gang? These connect to the corresponding black and white electrical wires that run from the switch to the electrical box where the existing fixture is installed. This makes for a safe protected circuit by having all grounds intact.
