The black of the 14/2 line wire will wire nut to the black of the 14/2 going to the first light switch.Light Fixture Power going out to Switch #1 The National Electrical Code requires a neutral at almost every switch. This j gives you 4 current carrying conductors along with a ground. In this scenario it will require you to run a NM 14/4 between the two switches. If your main power comes into the light fixture then from one switch to the next: Extra Wire - Extra wire is good for making pigtails.Wire Nuts - Wire nuts are used to tie wires together.Needle-nosed Pliers (Optional) - Needle-nosed pliers can be used to make the hooks on the end of wires.Electrical Tape - Electrical tape will be used to wrap the outlet around the termination screws as another layer of safety.Utility Knife - A utility knife will be used to remove the outer jacket to expose the individual wires.Wire Strippers - Wire strippers are used to strip the insulation off the individual wires.Screwdriver - A screwdriver will be used to make the wire terminations and install the cover of the outlet.Voltage Meter - A voltage meter allows you to verify the power is off.Read Also > How To Wire A 220-Volt Plug With 3 Wires? Supplies You'll Need To For 3-Way Switch Wiring For around the house projects it is good to have a few yellow and red wire nuts on hand. You need to have the correct size for the amount and gauge of wires that you will be using. The National Electrical Code requires devices to be wired so that if one has to be removed, it doesn't disrupt anymore down stream. This is a piece of wire about 6 inches long that will wire to the switch and then be tied in with other wires using a wire nut. When wiring up your switches you will need to create what is called a pigtail. A green screw - This is the ground screw, the bare copper ground wire will land here.Two lighter brass-colored screws - These are the traveler screws the traveler wires run in-between the two switches and MUST land on these screws.A dark colored screw - This is the common screw the wires carrying power to the switch or to a light get landed on this screw.Both ways are used frequently each creates unique ways on how the wires are run to the switches. One is by bringing the power into your switch box and the other is by having the power go to the light first. There is a couple of methods to get line power to your lights. NM 12/3 - 12 gauge wire with a yellow outer jacket enclosing 3 current carrying conductorsįor this guide we are going to assume you will be working with 14-gauge wire, though it is possible to have 12 gauge wire.NM 12/2 - 12 gauge wire with a yellow outer jacket enclosing 2 current carrying conductors and a ground.NM 14/3 - 14 gauge wire with a white outer jacket enclosing 3 current carrying conductors and a ground.NM 14/2 - 14 gauge wire with a white outer jacket enclosing 2 current carrying conductors and a ground.Most likely you will run into either 14 or 12 gauge wire, and 'in the trade' the cables are known as follows: NM comes in many different styles, but for this job you only need to be familiar with two of them: the 2-conductor and the 3-conductor. Homes are typically wired with NM cable this refers to the non-metallic outer jacket surrounding the individual wires. Electrical shocks can be very dangerous, and safety needs to be a priority! Most jurisdictions also require you to get an electrical permit to install new 3-way switch wiring, which will come with a small fee. It is very important that before beginning that you verify that there is no power on the wires you will be working with. When getting ready to wire, be sure you have the proper wire for your job! This allows you to control one or more lights from two different locations in your house. What You Need To Know When Wiring A Three Way Switch?Īnytime you use a 3-way switch, you will always have a pair of them.
