What is BS 442 - Terminals for electrical apparatus used for railway signalling purposes about?
BS 442 is a European standard that discusses terminals for electrical apparatus used for railway signalling purposes. BS 442 applies to the main terminals on electrical apparatus for railway signalling purposes, to which cables external to the apparatus are connected and ensure that the terminals for electrical apparatus maintain the acceptable standards.
Terminals of both the nut and the screw type, and the insulated screw type, are specified in BS 442.
Note: BS 442 is not intended to apply to terminals inside the apparatus.
Who is BS 442 - Terminals for electrical apparatus used for railway signalling purposes for?
BS 442 on terminals for electrical apparatus used for railway signalling purposes is useful for:
- Manufacturers of terminals for electrical apparatus
- Test centres or any person involved in the testing of terminals
- Regulatory authorities
- Design engineers
Why should you use BS 442 - Terminals for electrical apparatus used for railway signalling purposes?
A terminal is a point at which a conductor from a component, device or network comes to an end. Terminals are a class of electrical connectors that are used for the transfer of electrical current from a power or grounding source to a user.
BS 442 guides you regarding the screw threads, components and assembly, materials, and finish of terminals to manufacture durable and high-quality terminals for use in electrical apparatus for railway signalling purposes.
BS 442 also guides you on the dimensions for nut type terminals, screw-type terminals, and insulated screw-type terminals to manufacture terminals of the required size and thus, avoid wastage due to incorrect sized terminals.
With obedience and compliance to BS 442, you can enhance the efficacy of terminals for electrical apparatus used for railway signalling purposes.
