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 ...
Single-phase ~230 V/40 A/9 kW fuse box for apartment rewiring. Each appliance and each room are highlighted into autonomous circuits - this apartment has 14 individual circuits.
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 ...
An electrical drawing is a type of technical drawing that shows information about power, lighting, and communication for an engineering or architectural project.Any electrical working drawing consists of "lines, symbols, dimensions, and notations to accurately convey an engineering's design to the workers, who install the electrical system on the job".
Lighting and power receptacle circuits in North American systems are typically radial from a distribution panel containing circuit breakers to protect each branch circuit. [8] The smallest branch circuit rating is 15 amperes, used for general purpose receptacles and lighting.
The minimum required ingress protection rating in zone 0 is IPX7 in zone 1 and IPX4 in zone 2. If water jets are likely to occur, at least IPX5 is required in zones 1–3. Otherwise, in zone 3 and beyond, an ingress protection rating of IP20 is the minimum required. Equipment in zones 1 and 2 must be protected by a 30 mA residual current device ...
