Can a pluggable electrical connection be made in a cable duct?
‹ Terug naar overzicht- Can a pluggable electrical connection be made in a cable duct?
Answer: In our opinion, this question is not clearly addressed in NEN1010:2020. Our advice is as follows: • To lock any flying connections (1 male connector to 1 female connector) in cable trays. • To mount pluggable electrical connections with splitters on the outside of a cable duct using the mounting plate intended for this purpose, and to connect the connected cables to the pluggable electrical connection without mechanical strain (e.g. by relieving the strain on the cables by fitting them to the cable duct). And, of course, all connections must be locked.
Rationale:
- On the one hand, Section 2.15.04 indicates that in addition to cables, electrical equipment may also be located in a cable duct. This would then also apply to splitters or pluggable electrical connections, for example.
- Although Section 132.13 may be considered an article covering many unspecified situations, the installation must be provided with appropriate documentation. This also means that the installation must be made in such a way that the documentation is easy to interpret. However, the documentation requirements in Section 514.5.1 do not specifically state that the cable run / distribution must be visible. This is the case for some installations described in Part 7, for example Section 705.514.5.3 which applies to installations in agriculture, horticulture and livestock farming.
- Sections 132.12 and 526.3 state that all equipment must be set up so that connections are easily accessible for maintenance and inspection. However, Section 526.3 sets out exceptions that also apply to maintenance-free pluggable electrical connections. Wieland’s pluggable electrical connections are certified as maintenance-free and therefore do not necessarily have to be accessible.
- However, the following points are important:
- Section 134.1.4 states that connections must be reliable, and therefore pluggable electrical connections must be fitted with a locking device!
- Also, Section 522.8.9 requires that no mechanical forces act on conductors and connections, including pluggable electrical connections.
