In some instances, additional techniques not shown in this book may be required.

The projects in this book vary widely as to skill levels required: some may not be appropriate for all do-it-yourselfers, and some may require professional help.

Consult your local building department for information on building permits, codes, and other laws as they apply to your project. Typically, most simple home wiring projects are unaffected by the changes to the NEC, which is updated every three years. But according to top-notch home inspector Bruce Barker, who helped us update this book for its 6th edition, there are four code alterations that may impact homeowners and their DIY wiring projects soon.

Most local governing authorities use the NEC as the basis for their set of codes, although it usually takes a few years before the changes are adopted. And local codes always supersede any national codes. Here are the changes most likely to affect your wiring project, based on the new edition of the NEC: 1.

The available neutral at switch boxes. Some switch wiring methods require that the white wire be used and labeled as a hot wire. A single pole switch at the end of the circuit a switch leg is one example. Three- way and four-way switches are other examples. New computer-controlled and timer switches need power to operate, which means that a neutral wire is required to complete the electrical circuit. To allow easier installation of these new switches, the new NEC requires an available neutral wire in many switch boxes.

In most cases, you will just cap the neutral wire and leave it, looking a bit lonely, in the switch box. You may need to substitute 3-wire cable where you formerly used 2-wire cable, or you may need to substitute 2 runs of 2-wire cable where you formerly used 3-wire cable. Our new wiring diagrams will show you how to do this. When it goes into effect, this change will apply only to new construction and expanded circuits. AFCI protection for most circuits. The new NEC expands this requirement to include most 15 and 20 amp, volt, receptacle and lighting circuits.

Exceptions include the kitchen and bathroom receptacle circuits and the garage and exterior receptacle circuits. AFCI circuit breakers are required in most cases. Adding an AFCI device may not be as easy as installing it. Some AFCI devices may not be compatible with shared neutral multi-wire branch circuits. Some AFCI devices may not be compatible with dimmers, especially solid-state dimmers. You may want to have an electrician help you when you install AFCI devices.

Garage receptacles may not feed other outlets. You may no longer tie into a receptacle in your garage to power anything outside of the garage, such as an outdoor security light. Also, you must provide a receptacle for every parking spot in the garage. The most essential quality to appreciate about electricity is that the typical amounts that flow through the wires in your home can be fatal if you contact it directly. Sources estimate that up to 1, people are electrocuted accidentally in the U.

In addition, as many as die in fires from electrical causes. This chapter explains the fundamental principles behind the electrical circuits that run through our homes. The beginner should consider it mandatory reading. Even if you have a good grasp of electrical principles, take some time to review the material.

A refresher course is always useful. Electrical current flows in wires in much the same way that water flows Water flows under pressure inside pipes. In plumbing, water first flows through the pressurized water supply system. In electricity, current first flows along hot wires.

Current flowing Water supply pipe along hot wires also is pressurized. Electrical pressure is called voltage. Large supply pipes can carry a greater volume Drain pipe of water than small pipes. Likewise, large electrical wires carry more current than small wires.

This electrical current-carrying capacity of wires is called ampacity. Water is made available for use through the faucets, spigots, and showerheads in a home. Electricity is made available through receptacles, Water returns under no pressure switches, and fixtures.

Water finally leaves the home through a drain system, which is not pressurized. Similarly, electrical Water and electricity both flow. The main difference is that current flows back through neutral wires.

Power plants are located in all parts of electricity to large volt appliances such as clothes the country and generate electricity with generators dryers or electric water heaters.

Electricity that increase voltage to half a million volts or more. The travels through high-voltage transmission wires to service panel also contains fuses or circuit breakers communities that can be hundreds of miles from the that shut off power to the individual circuits in power plants. Certain substations then reduce the voltage for distribution high-wattage appliances, such as microwave ovens, are along street wires.

On utility power poles, smaller usually plugged into their own individual circuits to transformers further reduce the voltage to ordinary prevent overloads. Voltage ratings determined by power companies Wires carrying electricity to a house either run and manufacturers have changed over the years.

Most homes built after new devices connected to older wiring. For making have three wires running to the service head: two electrical calculations, use a rating of volts or power wires, each carrying volts, and a grounded volts for your circuits. Electricity from the two volt wires Power plants supply electricity to Substations are located near the Electrical transformers reduce thousands of homes and businesses.

A typical the high-voltage electricity that flows Step-up transformers increase the substation takes electricity from through wires along neighborhood voltage produced at the plant.

A utility pole transformer—or and reduces it for distribution along ground transformer—reduces voltage street wires. The mast is It is usually attached to the side of the house and connects supplied with three wires, two of which the insulated wires to the service mast.

The electric meter belongs to your each carry volts and originate at the nearest transformer. If you suspect the meter is not In some areas electricity enters from below ground as a functioning properly, contact the power company.

Current flows back to neutral at service mast Surges in current flow to grounding rod A grounding wire connects the electrical system to the earth Light fixtures attach directly to a household electrical through a metal grounding rod driven next to the house.

They are usually controlled with wall switches. The two common types of light fixtures are incandescent and fluorescent. According to box, distributes power to individual circuits. Fuses or circuit the National Electrical Code, all wire splices and connections breakers protect each circuit from short circuits and overloads. Switches control electricity passing through hot circuit Receptacles, sometimes called outlets, provide plug-in wires.

Switches can be wired to control light fixtures, ceiling access to electricity. A volt, amp receptacle with a fans, appliances, and receptacles. Most receptacles have two plug-in locations and are called duplex receptacles. Usually covered with white or light gray insulation.

Chandelier Wall switch Receptacles Switch loop Separate volt circuit for microwave oven oven. GFCI receptacles Separate volt circuit for water heater heater. Electric meter measures the amount the amount of electrical of electricity power consumed and displays Service panel distributes the measurement inside electrical power into circuits circuits.

Bonding wire to metal grounding rod rod. Bonding wire to metal water pipe pipe. Jumper wire is used to bypass the water meter and ensures an uninterrupted grounding bonding pathway pathway. Household circuits carry electricity from the main service panel, throughout the house, and Service back to the main service panel.

Several switches, panel receptacles, light fixtures, or appliances may be connected to a single circuit. Current enters a circuit loop on hot wires and Main circuit returns along neutral wires.

These wires are color Main circuit hot wires coded for easy identification. Hot wires are black neutral wire Circuit breakers or red, and neutral wires are white or light gray. For safety, all modern circuits include a bare copper or green insulated grounding wire. The grounding wire conducts current in the event of a ground fault see page and helps reduce the chance of severe electrical shock.

The service panel also has a bonding wire connected to a metal water pipe and a grounding wire connected to a metal grounding rod, buried underground, or to another type of grounding electrode. If a circuit carries too much current, it can overload. A fuse or a circuit breaker protects each circuit in case of overloads. Current returns to the service panel along a neutral circuit wire. Current then leaves the house on a large neutral service wire that returns it to the utility transformer.

Contrary to popular belief, electricity will take all available return paths to water and gas pipes are the most common examples.

A metal water and gas pipe could become energized by coming in contact with a damaged electrical wire. In a Metal gas pipe could become energized by a ground household wiring system, this return path is provided fault in a gas appliance such as a furnace.

A service panel. From the service panel, current returns person could receive a fatal shock if he or she touches along the uninsulated neutral service wire to a power energized metal that is improperly bonded, because pole transformer.

Bonding is also a fire safety system that in this and other books about electricity. These terms reduces the chance of electrical fires. Grounding also metal conduit, in a continuous low-resistance path provides a secondary return path for electricity in case back to the main service panel. If this metal becomes there is a problem in the normal return path.

The dead electrode. The most common grounding electrode circuit alerts people to a problem. Metal ufer ground. Current Service panel Black hot wire returns to Grounding wire transformer White neutral wire Grounding screw Grounding wire Loose hot wire Grounding wire to Grounding wire to grounding rods grounding rods 8 ft.

Small amount 8 ft. The grounding wire and bonded metal white neutral wire. Most current in the bonding and ground system flows back to the transformer; some may trickle out through the copper that leads to the grounding node.

By plugging a receptacles that accepted polarized plugs. The three-prong plug into a grounded three-slot receptacle, two-slot polarized plug and receptacle was designed to people are protected from ground faults that occur in keep hot current flowing along black or red wires and appliances, tools, or other electric devices. Use a receptacle adapter to plug three-prong The metal jacket around armored cable and plugs into two-slot receptacles, but use it only if the flexible metal conduit, widely installed in homes receptacle connects to a grounding wire or grounded during the s, provided a bonding path.

When electrical box. Note, however, mounting screw. The mounting screw connects the that deterioration of this older cable may decrease its adapter to the grounded metal electrical box.

Modern NM nonmetallic cable, Armored cable is sold pre-installed in Polarized receptacles have a long slot found in most wiring systems installed a flexible metal housing.

It contains a and a short slot. Used with a polarized after , contains a bare copper wire green insulated ground wire along with plug, the polarized receptacle keeps that provides bonding for receptacle black and white conductors. Flexible electrical current directed for safety.

Tamper resistent three-slot A receptacle adapter allows Double-insulated tools have receptacles are required by code three-prong plugs to be inserted into non-conductive plastic bodies to for new homes. They are usually two-slot receptacles. The adapter should prevent shocks caused by ground connected to a standard two-wire cable only be used with receptacles mounted faults. Because of these features, with ground. As with any tool purchase, The materials used for electrical wiring have changed dramatically in the last 20 years, making it much easier for homeowners to do their invest in quality products when you buy tools for own electrical work.

The following pages show electrical work. Keep your tools clean, and sharpen or how to work with the following components for replace any cutting tools that have dull edges. Electrical tapes in a variety of colors are used for cavities and for pulling wires through conduit. Products marking wires and for attaching cables to a fish tape. Although most household electrical repairs are simple and straightforward, the circuit breaker that controls the circuit you are servicing.

Then check to make sure the power is off by testing for power with a voltage tester. Tip: Test a live always use caution and good judgment when working circuit with the voltage tester to verify that it is working with electrical wiring or devices. Common sense can before you rely on it. Restore power only when the prevent accidents. The basic rule of electrical safety is: Always turn Follow the safety tips shown on these pages. At Never attempt an electrical project beyond your skill the main service panel, remove the fuse or shut off or confidence level.

Shut power OFF at the main service panel or the main Create a circuit index and affix it to the inside of the door to fuse box before beginning any work. Update it as needed. These fixture with a voltage tester. On damp floors, stand on a rubber mat or dry household repairs near the service mast. Extension cords are for temporary use only. Cords must be Breakers and fuses must be compatible with the panel rated for the intended usage. Never alter the prongs of a plug to fit a receptacle.

If Do not penetrate walls or ceilings without first shutting off possible, install a new grounded receptacle. Selecting the appropriate size and type and handling it correctly is absolutely necessary to a successful wiring project that will pass inspection.

Copper wire is the primary conductor of electricity in any home. The electricity itself travels on the outer surfaces of the wire, so insulation is normally added to the wires to protect against shock and fires. The insulated wires are frequently grouped together and bound up in rugged plastic sheathing according to gauge and function. Multiple wires housed in shared sheathing form a cable. In some cases, the wires are grouped in metal or plastic tubes known as conduit. Conduit also known as raceway is used primarily in situations where the cables or wires are exposed, such as open garage walls.

This chapter introduces some of the many varieties of wire, cable, and conduit used in home construction and explains which types to use where. It also will demonstrate the essential skills used to run new cable, install conduit, strip sheathing, make wire connections, and more. Solid copper wires are the best conductors of electricity and are In most wiring systems installed after , the wires and cables are insulated with plastic vinyl.

This type of insulation is very durable and can last as long the most widely used. Aluminum and copper-covered as the house itself. Before , wires and cables were insulated with A group of two or more wires enclosed in a metal, rubber. Rubber insulation has a life expectancy of about rubber, or plastic sheath is called a cable see photo, 25 years. Old insulation that is cracked or damaged opposite page. The sheath protects the wires from can be reinforced temporarily by wrapping the wire damage.

Conduit also protects wires, but it is not with plastic electrical tape. However, old wiring with considered a cable. An exception is a bare copper Wires must be large enough for the amperage grounding wire, which does not need an insulation rating of the circuit see chart, below right.

A wire cover. The insulation is color coded see chart, below that is too small can become dangerously hot. Wire left to identify the wire as a hot wire, a neutral wire, sizes are categorized according to the American Wire or a grounding wire. New cable sheathing is also Gauge AWG system. To check the size of a wire, use color coded to indicate the size of the wires inside.

Wire sizes shown actual size are categorized by the American In some circuit installations, the white wire serves as a hot wire Wire Gauge system. The larger the wire size, the smaller the AWG that carries voltage. If so, this white wire may be labeled with number. The ampacities in this table are for copper wires in NM black tape or paint to identify it as a hot wire.

The ampacity for the same wire in conduit is usually more. The ampacity for aluminum wire is less. Wires are covered with a layer of rubberized cloth, cloth fabric, but have butadditional no have no additional protection.

Metal clad cable MC and armored cable AC have been around since the s. Early versions had no grounding function, but existed solely to protect the wires that were threaded into it. Later armored cable products either had ground wire twisted in with the flexible metal cover or relied on the metal cover itself for connecting to ground. Modern MC contains an insulated ground wire along with the conductors. Metal conduit was installed during the middle of the 20th century as a way to protect hot and neutral conductors.

The conduit itself often was employed for connecting to ground. Early NM nonmetallic cable was used from until It features a rubberized fabric sheathing that protects individual wires. NM cable greatly simplified installations because separate wires no longer had to be pulled by hand through a conduit or armored cable.

Early NM cable had no grounding wire. NM cable nonmetallic was developed cable was around developed around The UF underground feeder cable has wires embedded in a solid-core plastic vinyl sheathing and includes a bare copper grounding wire. It is designed for installations in damp conditions, such as buried circuits.

It is available in lengths up to 25 ft. Or you can buy bulk cable B in any length. A NM nonmetallic sheathed cable should be used for most indoor wiring projects in dry locations. NM cable is sold in boxed rolls that contain from 25 to ft. B of cable. LearnEngineering team try to Helping the students and others who cannot afford buying books is our aim.
