What is BS 376-2 - Symbols for circuit diagrams about?
BS 376 is a standard that discusses railway signalling symbols.
BS 376-2 provides the best industry guidance on the specification for symbols for circuit diagrams to easily understand circuit diagrams.
BS 376-2 is the second part of a multi-part series that outlines the symbols to be used on railway signalling circuit diagrams but does not provide guidance on their application.
BS 376-2 also gives a standard system of nomenclature and labelling of wires such that each wire can be readily identified with that shown on the circuit diagram.
Note 1: BS 376-2 does not cover symbols for high voltage power distribution, telecommunications, or electronic products. These are covered in IEC 60617 or an appropriate British Standard.
Note 2: BS 376-2 does not include proprietary systems and specialized applications.
Note 3: The symbols in BS 376-2 provide for apparatus in general use. Wiring symbols have been designed so that they can be combined where one does not represent the complete device. If additional information is required to support the symbol, a “#” may be used to reference a note on the diagram.
Note 4: The size of symbols as drawn are in proportion but are not necessarily relative to one another; nor do they give the specific size to be used. The relative thickness of lines may also be varied, e.g., for contact elements.
Who is BS 376-2 - Symbols for circuit diagrams for?
BS 376-2 on symbols for circuit diagrams is useful for:
- Railway trains manufacturers
- Maintenance/technical staff for railways
- Test centres
- Regulatory authorities
Why should you use BS 376-2 - Symbols for circuit diagrams?
BS 376-2 guideline assists you with signalling relays diagrams, circuit diagrams, the electrical supply to railway signalling apparatus, and nomenclature for circuit diagrams for symbols for circuit diagrams.
BS 376-2 also guides on a list of figures on drawing of wires in written circuits, typical battery supply with intermediate terminal, examples of terminals for catch handle contacts, and more for symbols for circuit diagrams. in addition, provides a list of tables on the combination of wiring symbols examples, point operating mechanisms, point detectors, contacts of relays that are hinged at the arm, and more for symbols for circuit diagrams.
With compliance and obedience to BS 376-2, you can easily identify circuit diagrams and assist in the labelling of wires such that each wire can be readily identified.
