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.

May 11, 2018 Great Wiring Diagram For Horn Relay HORN RELAY Simple Wiring ...
I'm planning for a project where I need a NC relay with a 24 VAC coil to disable my AC condenser fan, and I could use help selecting a correct relay to use and ensuring it's wired correctly. The condenser fan (OFM in the 1st diagram) is pretty typical with 3 wires, 1 coming from the contactor (CC) and 2 coming from the run capacitor (RC).
The indoor fan relay was sticking in the energized position. Since replacing the relay with this one, the indoor fan turns on and off like it's supposed to. It's great to have it repaired for only $7.30 and a little labor, rather than the cost of a house call by an HVAC pro.
Our example for today's "how to" lesson is MotorTrend tech center technician Christian Arriero's 1974 Plymouth Duster.Christian picked up a Painless Performance electric fan relay kit with a ...
WIRING DIAGRAM COMPONENT LOCATIONS. When trying to locate a component in a wiring diagram and you don't know the specific system where it is located, use this handy component locator to find the system wiring diagram in which the component is located. Then, go to that system and locate the component within the wiring diagram.
The relay included with this kit is a 60 amp relay which is a pretty high rating for the wiring, but I've not yet seen even a pair of large fans pull more than 40 amps on cold start up. A small dab of teflon thread sealant at the very top of the threads is a good idea.

The third and last type of diagram is the installation diagram. This is a tool that is used primarily by the installing contractor. It normally shows only what the terminal board connections are, and very rarely will it include any internal wiring of the unit. Figure 3 is a typical installation diagram for a residential cooling system.
