So where do the wires go: And what if there is no ground wire? On a conventional volt “two pronged” electrical outlet that accepts grounded plugs two prongs plus the rounded center ground connector prong , your circuit will have three wires: You can see our white neutral wire connected to a silver screw on the receptacle in our photo. You will see the hot black wire connected to the bronze or darker-colored screw on the receptacle shown at below right. The receptacle we used for these photos happens to be a A rated device that permits the wire to be inserted straight into a clamp that is tightened against the wire by the screw. We don’t recommend using the push-in type backwire method that relies on a simple spring-clip connector inside the device. You can also see our ground wire connected at the left side of our previous photo, above-left. When wiring an electrical receptacle, what do I do with the red wire? Can I ground it?
How do I wire a double-switch light?
Most people ask if I can explain the RV electrical system in simple to understand terms. The electrical system in your RV can seem complex and confusing until you have a basic understanding of how it works. Your RV actually has three separate electrical systems. We are primarily concerned with the volt DC and volt AC coach systems. The majority of campgrounds you go to will provide you with an external volt electric source to plug into.
Light is controlled by two three-way switches with the light between the switches and the power first going through a switch, then to the light, and onto the second three-way switch. The ground wire is pigtailed with a wire connector at the switch boxes and the ceiling box.
Outdoor wiring projects are not difficult for a do-it-yourselfer, but, for safety reasons, outdoor wiring codes must be followed. Outdoor wiring projects fall into two general categories: Functional lighting illuminates high-use areas such as steps, stairs, gates, walkways, and outdoor grills. Decorative lighting adds dimension and mood to exterior space such as highlighting tress and shrubs with light.
Functional lighting can also be decorative. Local Codes First, contact the municipal building inspector to determine the requirements for outdoor wiring, if the home center or building material outlet where you do business doesn’t know. Sometimes these retailers service many different communities with many code variations, and, therefore, may not know specific codes in your specific neighborhood. In some areas, only a professional electrician can make the final electrical hookup.

Current flows through a switch to the load, such as a ceiling light. When you flip the switch off, it breaks the circuit and interrupts the flow of electricity. A basic light switch has two terminals and sometimes a ground terminal. The hot wire from the power source is connected to one of the terminals.
The hot wire going to the load such as a light is connected to the second terminal. Please read our safety information before attempting any testing or repairs. References to existing wiring assume that it is properly wired, which may not be the case in your home. Which Wires Get Connected to the Switch?
How to replace your old, outdated 3-way light switches
Sharp knife or slitting tool Wire strippers Drill with long auger electrician’s bit Coil of electrician’s fish wire Grounding screws Black tape Three-way switches require a three-wire cable: The cable should also have a ground wire, or a total of four wires in the cable. The system also requires three-way switches.
The switches are wider than regular single-pole switches and they have three terminal screws on the side sometimes back of the switch housing. Two terminals will be on one side of the switch housing; one terminal on the other side. Four-way switches have four terminals.
The mains hook up stuff consists off an RCD, two breaker, two sockets and a V mains indication light. The RCD and breakers are housed in the garage consumer unit (left). Each breaker feeds one socket which gives the option of a 6A feed and a 16A feed.
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.

Whether it’s trying to figure out that rat’s nest behind your television set or just simply changing over an electrical wall switch or outlet, I’m here to help. I’ll not only show you how to wire a 2-Way Switch or how to wire a 3-Way Switch or even how to wire an Outlet , but also teach you a little bit of theory on how the circuit is controlled.
From the standpoint of electrical engineering theory, the Philippine system is similar to that used in the U.S. and Europe. From the utility pole to the residence panel box we have one or two load wires and neutral conductor. We have a ground (earth) provided by the homeowner.
A good electrician can make those interactions easier in a hundred little ways, so it’s best to communicate your needs early—ideally after the house is framed and before the drywall or insulation goes up. That’s when master electrician Allen Gallant, who has wired many This Old House TV projects, takes his customers on a job-site walk-through, showing where he plans to put switches, lights, and receptacles.
Once Gallant starts wiring a house, virtually every aspect of his work is controlled by codes, both local and national. These codes are the final word on safe installation practices. Gallant is meticulous in adhering to them, yet he often goes a step further to make his electrical systems even safer and easier to use. On the following pages, you’ll see the basics of wiring a house to meet code, along with a look at Gallant’s extras.
When given a choice between installing outlet boxes made of blue PVC or those made of steel, Allen Gallant chooses plastic. But so is plastic—it’ll be around forever—and it’s about 70 percent cheaper. Local code has the last word, however; in some communities, plastic boxes are forbidden. Gallant does use metal boxes for one application: He learned that rule the hard way, when a heavy alabaster fixture broke loose from a plastic box and smashed to pieces on the floor.
Massachusetts requires electrical outlets every 12 feet; Gallant puts one every 8 feet. For added safety, Gallant mounts exterior floodlights controlled by a switch in the master bedroom.
What Wires Go to What When Hooking Up a Light Fixture?
Instructions Follow these steps to wire a volt switch: Find the electrical panel and turn off the circuit for the room that contains the switch that you will be working on. Test the outlet with a circuit tester to ensure that the circuit is off and the outlet is safe to work on.
The original light over the sink was rechromed, a new socket base with switch installed, and now uses a 12v E27 base bulb that screws right into the conventional V light bulb base. On the right is the sconces above the side windows with the same bulbs installed.
The single-pole switch is used when one or more lights are to be controlled from a single location. The 3-way switch is used in pairs when one or more lights are to be controlled from two locations. 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. The terminology used with these switches may sound daunting but the actual wiring is straight-forward and simple.
Check the wires in the device box with the non-contact voltage detector. The non-contact voltage tester will beep loudly if there is still voltage present in the box and remain silent if the circuit is safe to work on. 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. Wiring the light switches 1 Install a single-pole light switch by connecting the black wire entering the box to the bottom, brass-colored screw and the black wire leaving the the box to the top, brass-colored screw.
Make the connections by placing the wire loops under the screws in a right-hand direction and tightening the screw snugly down on the wires.

I assume that you mean the box on the ceiling has those wires in them, not the ceiling fixture that you bought, since that would have had a wiring diagram that explains what the wires would be for. If I had to guess, I would say that the box contains three wires because it may have had a ceiling fan that operated on a different switch than the light, or perhaps the light can be controlled from two different switches on different sides of the room, or perhaps both of these.
Do you have an AC voltage tester to see which wires are hot live and which are not? I hate to suggest this, but probably your best bet is to follow the wires back to their source to see what they are for. Do you have a false ceiling you can open up?
Choose Proper Switch: Make sure the timer is rated for the same amperage as your existing wiring. A amp timer will replace most standard light switches. Turn Off Power: Turn off the circuit breaker or unscrew the fuse that controls the wall switch and fixture. Remove Switch Cover Plate: Remove the cover plate and use an electrical tester to verify that the power is off.
First of all we should connect the ground wires to the box. If the light switch has a ground screw on it usually green and at the bottom of the switch , connect it now. Second twist the two white wires together and screw on a wire nut. It is usually a good idea to put some black electrical tape around the nut to make sure it doesn’t come off. These wires hold the power. Connect the “source” wire to the bottom terminal of the switch and the other black wire to the top terminal.
In this picture, you can see the strip gauge on the back of the switch. This gauge is when you want to use the “quick-connect” method when wiring a light switch. Simply strip the wire to the length specified and push the wire into the hole. Push the white wires into the box and screw the switch in place.
