Basic of wiring diagrams symbols

Some common symbols used in wiring diagrams are: · Switches – Symbols for switches may vary depending on the type, but generally, they are depicted by a rectangle, with two inputs and one output. The inputs may be labeled with letters or numbers, such as A and B, or 1 and 2. The output may be labeled with C or 3. The switch may also have a symbol inside the rectangle to indicate its function, such as a line for a normally open switch, or a dot for a normally closed switch . · Relays – These components are usually represented by a triangle, with three inputs and one output . The inputs may be labeled with letters or numbers, such as A, B and C, or 1, 2 and 3. The output may be labeled with D or 4. The relay may also have a symbol inside the triangle to indicate its function, such as a coil for an electromagnetic relay, or a spring for a mechanical relay . · Batteries – These components are represented by two or more parallel lines of different le

Mounting of cable routing

The installation film explains the cable ladder system and its variety. The different components from the track to the fittings and installation accessories are presented. The intelligent rung allows the cable ladders to be laid on both sides. Furthermore, the ladders can be installed both horizontally and vertically, either suspended or by direct wall mounting.

NATIONAL CAD STANDARD FOR ELECTRICAL DRAWINGS

1. Layering Layer Names: The NCS uses a hierarchical system for layer names, such as E-POWR for power systems, E-LITE for lighting systems, and so forth. Layer Filters: Helps in managing complex drawings by filtering layers based on their purpose. 2. Symbols Standard Symbols: Symbols for various electrical components like switches, outlets, lights, and junction boxes are standardized. Symbol Libraries: CAD software often comes with libraries that include these standardized symbols, ensuring consistency. 3. Annotations Text Styles: Typically, a simple, legible sans-serif font like Arial or Helvetica is used. Annotation Blocks: Predefined blocks for common annotations help maintain uniformity. 4. Drawing Set Organization Title Blocks: Standard title block formats including project information, sheet number, and drawing title. Sheet Order: General to specific order (e.g., general notes, plans, details, schedules). 5. Sheet Identification Sheet Numbering: A systematic approach like E101 fo
