Residential electrical wiring systems start with the utility's power lines and equipment that provide power to the home, known collectively as the service entrance. The power is run through an electric meterwhich records how much energy is used in the home and is the basis for the monthly electric bill. In general, the utility company's jurisdiction stops with the meter. After that point, all of the electrical equipment is the homeowner's responsibility. The service entrance is the equipment that brings electrical power to the home.
Most residential service includes three wires: two cables carrying volts each for a total of volts and one grounded neutral wire. If the cables are hung overhead, they are collectively called a service drop. If they are routed underground, they are known as a service lateral. A service drop connects to the home at a service head, or weather head, on the roof or exterior wall of the house. Once the power reaches the house via the service drop or service lateral cables, it passes through the electric meterwhich may be mounted on an exterior wall or may be located inside the home's breaker box.
The meter records all electricity used by the home, measured in kilowatt-hours, or kWh. A watt light bulb burning for 10 hours uses 1 kWh of electricity.SUPER EASY Boat Wiring and Electrical Diagrams - step by step Tutorial
Meters may be analog or digital type, although most new meters are digital and can be read remotely by the utility company. The main service panel, commonly known as the breaker box or circuit breaker panel, distributes power to all circuits throughout the building.
Each circuit has a breaker that can shut itself off in the event of a short circuit or overload to cut power to the circuit.

Old homes may have fuses instead of breakers. Fuses are just as effective as breakers, but most new panels today use breakers instead of fuses. It is important to note that power coming from the service lines to the electric meterand then to the main service panel, is always live.
Before working on these areas the power company must shut off the power. The power going out of the panel to the household circuits can be shut off by the main breaker in the service panel, but the power coming into the panel is not affected by the main breaker.The book is complete with and electrical codes for each project that are easy to understand, along with hundreds of on the job photos.
During the past several years while answering over electrical questions, Dave has been requested by many people to write a home wiring book. He began his writing project by researching what people were looking for which was the ideal book Dave wanted to produce: A practical guide to wiring written by an electrician featuring actual on the job experiences with electrical codes that were organized and easy to understand.
He is happy to say that this book is now available and will be of great benefit for the homeowner, students and teachers, electricians and inspectors. He is experienced with industrial, commercial and residential construction of both new and remodel projects. The work he has enjoyed most has been wiring custom homes in some of the most beautiful areas of California. As an electrical contractor, Dave has seen many projects performed by well-meaning people that are serious fire and safety hazards.
Dave has now combined his knowledge with the requests from others to produce a book that offers a full resource for home electrical wiring.

Contact your local building authority for complete information. NEC NEC Only one conductor shall be installed under a terminal screw.
In boxes with more than one ground wire, the ground wires shall be spliced with a wire tail, or pig tail attached to the grounding terminal screw. NEC and Wire Splices All splices, including ground wires, shall be made with an approved splice cap or wire nut and shall be made in approved electrical boxes or enclosures.
Switches, including dimmer switches, shall be grounded and shall provide a means to ground metal plates. NEC All conductors of the same circuit, including grounded conductors, shall be contained in the same raceway, cable, or trench. All switches, including dimmer switches, shall be grounded. NEC At all boxes there shall be a minimum wire length of 6 inches, with at least 3 inches outside the box.
When openings in non-metallic boxes are broken out and not used, the entire box must be replaced. NEC Type NM cable shall not be installed in spaces used for cold air returns, however NM is permitted to pass through perpendicular to the long dimension of such spaces.
However, if a single gang device box without a clamp is used, the cable shall be secured within 8 inches of the box. NEC The volume of electrical boxes shall be sufficient for the number of conductors, devices, and cable clamps contained within the box. Nonmetallic boxes are marked with their cubic inch capacity.

Wiring for modern homes is quite standard, and most homes built after the mids have similar types of wiring. Any new electrical installation requires new wiring that conforms to local building codes.
Here are some common types of home electrical wire. It helps to understand a few basic terms used to describe wiring. In the case of household wiring, the conductor itself is usually copper or aluminum or copper-sheathed aluminum and is either a solid metal conductor or stranded wire.
Most wires in a home are insulated, meaning they are wrapped in a nonconductive plastic coating. One notable exception is ground wires, which are typically solid copper and are either insulated with green sheathing or uninsulated bare.
The most common type of wiring in modern homes is in the form of nonmetallic NM cablewhich consists of two or more individual wires wrapped inside a protective plastic sheathing.
The Circuit Detective
As an alternative to NM cable, individual wires can be installed inside of a rigid or flexible metal or plastic tubing called conduit. Conduit is typically used where the wiring will be exposed and not hidden inside walls, floors, or ceilings. These larger wires in your home are carrying circuit voltage, and they can be very dangerous to touch. There are also several wires in your home that carry much lesser amounts of "low-voltage" current.
These are less dangerous, and with some, the voltage carried is so low that there is virtually no chance of shock.
However, until you know exactly what kind of wires you are dealing with, it's best to treat them all as dangerous. Most NM cables have a flattened tubular shape and run invisibly through the walls and floor cavities of your home. Almost all of the wiring in outlets and light fixtures a modern home is NM cable.
NM cable is now sold with a color-coded outer jacket to indicate its wire gauge:. NM cable is dangerous to handle while the circuit handles are carrying voltage. Image courtesy of Amazon. Underground Feeder UF is a type of nonmetallic cable designed for wet locations and direct burial in the ground. It is commonly used for supplying outdoor fixtures, such as lampposts. Like standard NM cable, UF contains insulated hot and neutral wires, plus a bare ground wire.
But while sheathing on NM cable is a separate plastic wrap, UF cable sheathing is solid plastic that surrounds each wire. UF cable is normally sold with gray outer sheathing. UF cable is also used for major circuit wiring, and it carries a dangerous amount of voltage as long as the circuits are turned on.
Unlike NM cable, in which two or more individual insulated conductors are bundled inside a plastic sheathing, THHN and THWN wires are single conductors, each with its color-coded insulation. Instead of being protected by NM cable sheathing, these wires are protected by tubular metal or plastic conduit. Conduit is often used in unfinished areas, such as basements and garages, and for short exposed runs inside the home, such as wiring connections for garbage disposers and hot water heaters.If you are a Homeowner This will save you on your next electrical project.Cisco sg250 dhcp relay
