Each appliance and each room are highlighted into autonomous circuits - this apartment has 14 individual circuits. A relay is used to control the light fixtures in a large room. In new home construction, wiring for all electrical services can be installed before the walls are finished.
A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. 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 ...
Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle) symbol for insulated wires in non-CAD schematics is recommended (as opposed to using the CAD-style symbol for no connection), so as to avoid confusion with the original, older style ...
They may not show all the conductors and termination points. Except for one-line diagrams, this should show all the circuit nodes. One-line diagrams represent the three or four conductors of three-phase power circuits with one line. Wiring diagrams are sometimes made. These show and name the termination points and names of each conductor.

First-generation wiring systems became susceptible to abuse by homeowners who would replace blown fuses with fuses rated for higher current. This overfusing of the circuits subjects wiring to higher levels of current and risks heat damage or fire. Knob-and-tube wiring may also be damaged by building renovations. [11]
A circuit diagram representing an analog circuit, in this case a simple amplifier. Analog electronic circuits are those in which current or voltage may vary continuously with time to correspond to the information being represented. A simple schematic showing wires, a resistor, and a battery
