  2. Wiring diagram - Wikipedia

    en.wikipedia.org/wiki/Wiring_diagram

    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 ...

    en.wikipedia.org/wiki/Utility_submeter

    A typical residential water meter A typical residential digital electric submeter Before submetering, many landlords either included the utility cost in the bulk price of the rent or lease , or divided the utility usage among the tenants in some way such as equally, by square footage via allocation methods often called RUBS (Ratio Utility ...

  4. Electrical system design - Wikipedia

    en.wikipedia.org/wiki/Electrical_system_design

    A wire list is made in spreadsheet or list format. It shows the electrical assembly people what wires are to be connected and to where. When it is printed out on paper, it is easy for the assembly people to check off conductors as they are connected. The wire list contains at a minimum each wire name, terminal name, and wire model number or gage.

  5. Circuit diagram - Wikipedia

    en.wikipedia.org/wiki/Circuit_diagram

    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.

  6. Single-line diagram - Wikipedia

    en.wikipedia.org/wiki/Single-line_diagram

    In power engineering, a single-line diagram (SLD), also sometimes called one-line diagram, is a simplest symbolic representation of an electric power system. [1] [2] A single line in the diagram typically corresponds to more than one physical conductor: in a direct current system the line includes the supply and return paths, in a three-phase ...

  7. Electrical wiring - Wikipedia

    en.wikipedia.org/wiki/Electrical_wiring

    Installing electrical wiring by "chasing" grooves into the masonry structure of the walls of a building. Materials for wiring interior electrical systems in buildings vary depending on: Intended use and amount of power demand on the circuit; Type of occupancy and size of the building; National and local regulations

  8. Distributed-element model - Wikipedia

    en.wikipedia.org/wiki/Distributed-element_model

    Fig.1 Transmission line. The distributed-element model applied to a transmission line. In electrical engineering, the distributed-element model or transmission-line model of electrical circuits assumes that the attributes of the circuit (resistance, capacitance, and inductance) are distributed continuously throughout the material of the circuit.

  9. Knob-and-tube wiring - Wikipedia

    en.wikipedia.org/wiki/Knob-and-tube_wiring

    [4] [citation needed] This direct routing method has the advantage of reduced cost by allowing use of the shortest possible lengths of wire, but the major disadvantage is that a detailed building wiring diagram is needed for other electricians to understand multiple interwoven circuits, especially if the wiring is not fully visible throughout ...
