Full title and description

STB VDE 0604-2-4 / DIN EN 50085-2-4:2010-04 — Cable trunking systems and cable ducting systems for electrical installations. Part 2-4: Particular requirements for service poles and service posts (German version of EN 50085-2-4:2009). This document specifies particular requirements and tests for freestanding installation units (service poles / service posts) used to accommodate and, where required, provide protective separation for insulated conductors, cables and ancillary electrical equipment in electrical and communication installations.

Abstract

This standard defines the design, construction, classification and test requirements for freestanding cable trunking and ducting installation units (service poles and posts). It addresses mechanical, electrical and environmental properties relevant to safe installation and operation up to the rated voltages covered by the parent standard, and gives criteria for mounting, accessibility, segregation of circuits and tests to verify conformity. The standard applies to installations with maximum voltages up to 1 000 V a.c. and 1 500 V d.c. where specified.

Scope

This part of the EN/DIN standard series covers particular requirements and tests that apply to freestanding installation units (service poles and service posts) intended to provide routes and support for insulated conductors, cables and associated equipment within buildings and similar installations. It applies where such units are used as part of electrical or communication installations with rated voltages up to 1 000 V a.c. and 1 500 V d.c., and it complements the general requirements of Part 1 and other parts of the EN 50085 series. Excluded are systems covered by other standards (for example cable tray, ladder systems, conduit systems and busbar trunking covered by their own standards). The document also describes mounting options, segregation requirements, mechanical strength and electrical separation tests specific to service poles/posts.

Key topics and requirements

• Definitions and classification of freestanding installation units (service poles / service posts).
• Mechanical requirements: stability, impact resistance, resistance to static and dynamic loads for freestanding mounting.
• Electrical requirements: clearances, creepage, electrical separation where required, and suitability for specified maximum voltages (≤ 1 000 V a.c. / ≤ 1 500 V d.c.).
• Segregation and wiring accommodation: separation of circuits, compartmentation, and internal arrangement for cables and accessories.
• Mounting and installation: requirements for anchoring, floor fixing, and if applicable, weighted or hinged arrangements for safe freestanding use.
• Type and routine tests: electrical, mechanical and environmental tests to verify conformity with the particular requirements of Part 2-4.
• Marking and documentation: required information for safe installation and use, including voltage ratings and manufacturer instructions.

Typical use and users

Used by manufacturers of cable trunking and service pole systems, testing laboratories, product designers, electrical installers, consulting engineers and compliance officers. Typical applications include open-plan offices, public buildings, retail spaces and temporary installations where freestanding service posts provide power and communications distribution without permanent wall or ceiling mounting. Installers and specifiers rely on this part for product selection, type testing and ensuring safe separation of circuits within freestanding columns.

Related standards

This part is one element of the EN 50085 (Cable trunking and cable ducting systems) series; related documents include Part 1 (general requirements), other Part 2xx documents covering different particular requirements, and product-family standards that may cover conduit, cable ladder, tray and busbar trunking systems. The document has later editorial corrections (Berichtigung 1:2020) and national adoptions; note that the EN/DIN series continued to be updated in later years under IEC/EN harmonized numbering (e.g., conversion to EN IEC 61084-series documents). Users should check national standards bodies for the most recent consolidated edition.

FAQ

Q: What is this standard?

A: It is the German national adoption (VDE/DIN) of EN 50085-2-4:2009 published as DIN EN 50085-2-4 (VDE 0604-2-4) specifying particular requirements for freestanding service poles and service posts used in electrical and communication installations.

Q: What does it cover?

A: It covers definitions, classification, mechanical and electrical requirements, mounting and installation rules, segregation of circuits, and type/routine tests specific to freestanding cable trunking/service pole systems — for use up to 1 000 V a.c. and 1 500 V d.c. It complements the general requirements in Part 1 and other parts of the series.

Q: Who typically uses it?

A: Manufacturers, product designers, testing laboratories, installers, electrical engineers and specifiers who design, produce, test or install freestanding service poles/posts for building electrical and communication distribution.

Q: Is it current or superseded?

A: The DIN EN 50085-2-4 (VDE 0604-2-4) edition referenced here was published nationally in April 2010 and has a published correction (Berichtigung 1) from July 2020. Users should verify national catalogues for later consolidations or supersessions: the EN/IEC numbering for cable trunking standards has been subject to revision and replacement work (documents under the EN IEC 61084 series have been introduced in later years). As of the publication information available here this 2010/2020-corrected edition remains the documented DIN/VDE adoption, and further consolidated editions under IEC/EN numbering were announced for release in later program cycles — check your national standards body for the absolute latest effective date before relying on a supersession.

Q: Is it part of a series?

A: Yes — it is Part 2-4 of the EN 50085 series (Cable trunking and cable ducting systems). The EN 50085 series contains Part 1 (general requirements) and several other Part 2/x documents addressing particular product types; the family has later been harmonized with the EN IEC 61084 series in subsequent revisions.

Q: What are the key keywords?

A: Cable trunking, cable ducting, service pole, service post, freestanding installation, VDE 0604, DIN EN 50085-2-4, electrical installation, segregation, mechanical testing.
