Wiring Diagram Letters

The letter part of the name identifies the type of component r s for resistors c s for capacitors u s for integrated circuits etc.

Wiring diagram letters. Each component name on a schematic should be unique. The number is sometimes followed by a letter indicating that components are grouped or matched with each other e g. Electrical symbols and electronic circuit symbols are used for drawing schematic diagram. Wiring sold for electrical projects often carries labeling to help you choose the right product for your needs.

A wiring diagram is used to represent how the circuit generally appears. The symbols represent electrical and electronic components. Standard auto wire diagrams pdf automotive wiring diagrams. If you have multiple resistors in a circuit for example they should be named r 1 r 2 r 3 etc.

A reference designator unambiguously identifies a component within an electrical schematic or on a printed circuit board the reference designator usually consists of one or two letters followed by a number e g. Rb is red with a black tracer. Automotive wiring diagrams and electrical symbols. The color is shown as a two letter code which can be identified by referring to the wire color code chart fig.

Wiring diagrams show components mounted in their general location with connecting wires. 1 which identifies the main circuit part of the main circuit gauge of wire and color. Wiring code identification information wire code identification each wire shown in the diagrams contains a code fig. At first glance the repair diagram may not convey how the wires use many colors and diameters.

They show the diameter of each wire using a label placed at some point along side its drawn line 1 0 8. Component names help us reference specific points in. Components such as diodes transistors and integrated circuits don t have values. This represents an orange colored wire with a black tracer stripe.

Instead they have manufacturer s part numbers. The letters k and m are used to denote thousands and millions. Schematic diagrams are used to troubleshoot and install control circuits. These can take some effort to locate on fold out map type diagram.

Schematics are generally easier to read and understand than wiring diagrams. Electrical symbols electronic symbols. For example a 10 000 ω resistor is identified as 10k in a schematic. Letters numbers and wording on wiring labels tell you important information such as the wire material the size of the wire and the type of insulation used on the conducting wires.

An example would be the letters ob.
