A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the power and signal connections between the devices.
A wiring diagram usually gives information about the relative position and arrangement of devices and terminals on the devices, to help in building or servicing the device. This is unlike a schematic diagram, where the arrangement of the components' interconnections on the diagram usually does not correspond to the components' physical locations in the finished device. A pictorial diagram would show more detail of the physical appearance, whereas a wiring diagram uses a more symbolic notation to emphasize interconnections over physical appearance.
A wiring diagram is often used to troubleshoot problems and to make sure that all the connections have been made and that everything is present.
Architectural wiring diagrams show the approximate locations and interconnections of receptacles, lighting, and permanent electrical services in a building. Interconnecting wire routes may be shown approximately, where particular receptacles or fixtures must be on a common circuit.
Wiring diagrams use standard symbols for wiring devices, usually different from those used on schematic diagrams. The electrical symbols not only show where something is to be installed, but also what type of device is being installed. For example, a surface ceiling light is shown by one symbol, a recessed ceiling light has a different symbol, and a surface fluorescent light has another symbol. Each type of switch has a different symbol and so do the various outlets. There are symbols that show the location of smoke detectors, the doorbell chime, and thermostat. On large projects symbols may be numbered to show, for example, the panel board and circuit to which the device connects, and also to identify which of several types of fixture are to be installed at that location.
A set of wiring diagrams may be required by the electrical inspection authority to approve connection of the residence to the public electrical supply system.
Wiring diagrams will also include panel schedules for circuit breaker panelboards, and riser diagrams for special services such as fire alarm or closed circuit television or other special services.

Electrical Wiring Symbols. When looking at any switch diagram, start by familiarizing yourself with the symbols that are being used. The electrical symbols will not only show where something is to be installed, but what type of device is being installed.
How to Distribution Board Wiring Diagram for Single phase Wiring with DP MCB, SP MCB, earth, voltmeter, ammeter for Home wiring In the above diagram I have shown the complete method of wiring, I wired an energy meter after that a double pole, and then single pole breakers for each room or each point of circuit load.

Wiring Color Code: ... fan and TV in each room to be connected to a single phase UPS. The electrical contractor is asking for high extra payment for doing this. Would there be significant extra cost involved.
The electrical wiring inside both of indoor and outdoor units is more complicated than that of window air conditioning units. It is always factory wiring and from our point of view as electrical power engineers, it will not affect our work at all.
Depends on personal level experience, ability to work with tools, install electrical circuit wiring, and the available access to the project area. Electrical Safety: Identify the panel circuits found in the project area, turn them OFF and Tag them with a Note before working with the electrical wiring. Electrical Wiring Parts and Materials:
Connector Joining Wire Harness and Wire Harness: IA1 Gray (Europe), IA2 Gray (General), IB1 Green, IB2 Green, IC1 Gray, IC2, IE1, IG1, IN1 Yellow
A house electrical plan, also called the house wiring diagram, is the visual representation of the entire electrical wiring system or circuitry of a house (or a room).
Heat pump thermostat wiring A typical wire color and terminal diagram. As shown in the diagram, you will need to power up the thermostat and the 24V AC power is connected to the R and C terminals. The color of wire R is usually RED and C is BLACK. C is known as the common terminal. These two connections will ensure that there is power to the thermostat that you are operating.
General Diagram Types. Edraw defines some general diagram types, and divides them into various categories. Every diagram type has specific shapes and examples.
