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 particuular receptacles or fixtures must be on a common circuit.
Architectural style wiring diagram, with lamps and switches shown symbolically in their physical locations on the plan view of the building.
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.

Wiring Diagram for Forced Air
Wiring Diagram for Forced AirConnect a wire from "R" on your existing
thermostat to "R" on the additional thermostat
then connect a wire from "G" on your existing
thermostat to "W" on the additional thermostat.
The additional thermostat is set to a higher temperature
to allow the blower fan to run
without running the furnace.
This is one of several variations.
If air conditioning is present, a
snap disc temperature control
should be installed on the heat
exchanger manifold to provide
an interlock for the air conditioner.
This prevents the air conditioner
from operating when the water
temperature is higher than 140F.
Thermostats may vary in
style. This is an example
illustration only.
In order for this system to
operate properly, a mini-
mum of 3 wires are re-
quired on the existing
thermostat to have both
fan and heat features. In
order for this system to
operate properly, the "G"
terminal on the existing
thermostat must be con-
nected to the furnace fan
relay.
