how to wire a three way switch

How to wire a three way switch

I don't wire enough three way switches to keep the logic straight in memory, so I made a logic diagram of several ways they can be wired and a PDF version of this diagram to print out.

A three-way switch has four screw terminals

  • green ground screw for the green or bare ground wire which is used to ground the switch to the main electrical panel.
  • dark common screw for the hot wire which either comes from the main electrical panel or goes out to the fixture, depending on where the switch is in the circuit.
  • Two brass traveler screws for the hot wires which run from one switch to the other.

Switches interrupt only the hot wire to the light fixture

  • Switches never interrupt the neutral wire or the ground wire.
    • The ground wire is connected to the switch to ground its metal parts for safety.
    • The neutral wire is never connected to a switch.

CAUTION - the white wire may be hot

You'll note in the diagram that in some wiring schemes the white wire is used as a hot feed. This is contrary to the general rule that the white wire is grounded at the main electrical panel. So, as always in working with electric wiring, never assume a wire is dead. Turn the circuit breaker off. Test it. Test it again. Be careful.

If you want more information The Home Improvement Web has a good article with details about how to install a three way switch.

How Much Does it Cost to Wire a House?

How much does it cost to wire a house these days? You need to take several things into consideration such as size, location, specification etc. This article gives you tips on what technical aspects you need to be aware of, avoid the pitfalls and get the best price to wire your house.
1) The Size Of Your House
The size of your house directly affects the cost. The cost of wire,  outlets, switches etc will increase proportionally with the increase in square feet of your property. Of course other factors like whether it is single/multi storey, the layout etc will affect the price.
If it is a new house build you will also have to factor in the cost of connecting to the grid, which can be very expensive depending on location.
2) The Current System
Is the house running an older fuse-type system or a circuit breaker system? If you are unsure, ask the electrician when they are quoting what type of system it is.
3) Planning For The Future
This type of work is done rarely so make sure you plan it carefully. In addition to the standard outlets, lighting etc you may want to have external power to a garage, patio or deck. It is cheaper to have all the work done in one go rather than doing a further project later so plan for all eventualities.
If you are planning to sell the house in future, a good idea is to take photo's or video of the work being done so you can prove you had the work done to any prospective buyer.
4) Walls and Finishing
If your walls are made from solid brick there will a be more work to chase out spaces for the wires. If your walls are plasterboard, it will be much easier. Remember also you will have an additional cost to plaster/finish the walls, so factor this cost into your budget.
5) General Tips
a) Do not attempt the work yourself unless you are qualified. Electricity is potentially lethal so ensure your electrical contractor is a member of trade associations and their work is up to local safety standards. It is your family's life you are risking by cutting corners.
b) Always get 3-5 prices, and be prepared to haggle. With the current financial climate you will be able to find a great deal. A reputable firm will not ask for payment up front and give you a free estimate.
c) Get a fixed price and do not deviate from the original specification once the project is underway, this will just increase the cost.
d) Choose a timescale that suits you and the contractor. There will be a lot of disruption while the work is underway so discuss your requirements in detail and get a written agreement on what work will be carried out.
e) Get the relevant inspection certificate on completion (don't pay in full until you receive this).
f) Get recommendations from family and friends. Price is not the only consideration.
As a rule of thumb, for an average sized house, with regular fixtures and fittings, you will be looking at a cost of $2000-$5000.
This should answer the question how much does it cost to wire a house. Make sure you do some planning, find out the size of your house and what specification you need and you will able to find a suitable contractor and most importantly the best price.
Mike Donaldson has been an electrical contractor for over 30 years. Here are his recommended websites to find reliable electrical contractors and home improvement contractors.

how to wire a light switch

Wiring a Light Switch - End of Circuit

The easiest place to wire a light switch is at the end of a circuit. This does not mean that you should plan all your circuits so that your light switches are necessarily at the end. A light in the middle of a circuit really isn't that much harder.
Before beginning any electrical work, it is wise to turn off the circuit and then to test to make certain that the circuit is indeed off with a circuit testing device. Circuits generally use either 12 or 14 gauge wire. In wire gauges, the bigger number designates a smaller diameter wire. As a rule of thumb you should use 12 gauge wire for 20 amp circuits and 14 gauge wire for 15 amp switches.
When placing the switch boxes, be sure to choose an easily accessible spot near the door about hand height. If you are in doubt as to where this should be, examine the positioning of other switches in your house. If you haven't any installed yet, 45 to 48 inches from the floor should work about right. It is best to make them all about the same.
In our diagram the source of power comes through the switch box. The black wire, which is the "hot" wire leads directly to the bottom connector on the switch. The switch, of course, should be oriented so that the "on" position is up and the "off" position is down. On most switches there are two ways to connect the wire to the switch. There are two little holes in the back of the switch as well as two screws on the side. You can either push the stripped wire (About 1/2 inch of the insulation can be removed with a wire stripper or more laboriously with a utility knife.) into the hole or curve it into a hook with a pair of pliers, wrap it around the appropriate screw and then tighten the screw.
Meanwhile, you should have set up the box for the light and run a wire between the two boxes. The white wire from the source is connected to the white wire from the light. Our diagram shows a ground wire connection (usually bare or green) directly to the box. This is only necessary on a metal box. On a plastic box merely connect all of the ground wires together. Take the black (hot) wire that leads from the light and connect it to the top connector on the switch. Now twist the white wires together and use a cap or electrical tape to insulate the splice.
In the light box, connect the black and white wires to the light, this will generally be a fairly obvious process as most lights come with both black and white wires as well as a ground connection. If the light is one of the simpler ones, you can generally distinguish between the connectors, one will usually be made of wire that is silver in color, the other will be vaguely brass. The ground wire can be hooked directly to a metal box or to a connection on the light itself. Sometimes there will be a green wire.
Generally, it is wise to test your light before screwing the switch into the wall or the light into the ceiling. Test again after all the components are made secure.
If you are in any way confused by this explanation, please refer to our diagram.
