Overview

HD 60364-7-729:2009/A11:2017 is a CENELEC harmonization document that amends the HD 60364-7-729:2009 rules for low-voltage electrical installations specifically addressing operating and maintenance gangways. Published in August 2017, this amendment (A11) updates requirements for safe access, clearances and passageways used for operation and maintenance of LV electrical equipment. The document is published in English, French and German and is intended for adoption by CENELEC member bodies.

Key topics and requirements

The amendment focuses on practical safety and access details for gangways in electrical installations. Key technical topics include:

• Gangway widths and minimum clearances between barriers, enclosures, switch handles and walls to ensure safe operation and maintenance.
• Distance requirements: amendment A11 records changes to national provisions (example: Denmark’s minimum distance of 700 mm between barriers/enclosures or switch handles and the wall or opposite limit of the gangway).
• Annex modifications: changes to Annex ZB and additions to Annex A (A.1) clarify national application and door/circuit-breaker considerations for maintenance positions.
• Harmonization and national implementation rules-outlining latest dates for national adoption and withdrawal of conflicting standards (dop 2018-05-31; dow 2020-05-31).

Note: this summary reflects the amendment content; designers should consult the full published text for complete specifications and dimensional tables.

Applications and who uses it

This standard is used where safe access to low-voltage switchgear and control equipment is required:

• Electrical designers and engineers specifying layout and clearances in switchrooms, control rooms and plant electrical rooms.
• Installers and contractors implementing gangways and barriers to meet regulatory safety distances.
• Maintenance teams and safety managers ensuring adequate access during operation and service.
• Inspection bodies and regulators verifying compliance with harmonized LV installation rules.
• Manufacturers and integrators of switchgear designing enclosures and access arrangements.

Practical scenarios include planning maintenance aisles in substations, arranging clearances for withdrawable circuit-breakers, and designing doors or barriers that can be fixed open for servicing.
