IEC 61439-7:2022

Overview

IEC 61439-7:2022 is the International Electrotechnical Commission standard that defines specific requirements for low-voltage switchgear and controlgear assemblies used in public outdoor and semi-public sites - notably marinas, camping sites, market squares, and electric vehicle charging stations (AEVCS). It applies to assemblies with rated voltages up to 1 000 V AC or 1 500 V DC, intended for generation, distribution, conversion and control of electrical energy and expected to be operated by ordinary persons (for example, to plug/unplug equipment). This second edition (2022) replaces the 2018 edition and is a technical and editorial revision.

Key technical topics and requirements

IEC 61439-7 supplements the general rules of IEC 61439-1:2020 and adds application-specific requirements. Key topics include:

• Interface characteristics and information for safe installation and use
• Service conditions for outdoor public and temporary installations
• Constructional requirements addressing mechanical strength, enclosure protection and accessibility
• Performance requirements for electrical and mechanical behaviour under real-world conditions
• Design verification and routine verification procedures, including tests for endurance, static and impact loads (see annexes such as Annex CC and mechanical test figures)
• Requirements for assemblies intended for EV charging (AEVCS) integrating Mode 3 and Mode 4 conductive charging functionality in accordance with IEC 61851-1:2017
• Normative references and environmental/mechanical tests (for example, IEC 60068 series for shock and hammer tests, IEC 62262 IK code for impact resistance)

Practical applications and who uses this standard

IEC 61439-7 is essential when designing, manufacturing, testing or specifying outdoor power distribution assemblies and cabinets that are accessible to the public, including:

• Assembly manufacturers producing pedestals, kiosks or cabinets for marinas, campsites, market stalls or EV charging points
• System integrators and electrical designers specifying safe, compliant outdoor distribution solutions
• EV charging station suppliers integrating AEVCS for Mode 3 and Mode 4
• Testing laboratories and certification bodies performing design and routine verifications
• Site operators and installers responsible for public safety, durability and regulatory compliance

Benefits include improved safety for ordinary users, documented verification evidence, and clearer interoperability with EV charging standards and national wiring regulations.
