Low-voltage electrical installations - Part 7-706: Requirements for special installations or locations - Conducting locations with restricted movement
The particular requirements of this part apply to fixed equipment in conducting locations where movement of persons is restricted by the location, and to supplies for portable equipment for use in such locations. A conducting location with restricted movement is comprised mainly of metallic or other conductive surrounding parts, within which it is likely that a person will come in contact through a substantial portion of his body with the metallic or other conductive surrounding parts and where the possibility of interrupting this contact is limited.

Les exigences particulières de la présente partie s'appliquent aux matériels fixes des enceintes conductrices exiguës et à l'alimentation des appareils portatifs à l'intérieur de ces enceintes. Une enceinte conductrice exiguë est un local ou emplacement de travail dont les parois sont essentiellement constituées de parties métalliques ou conductrices, à l'intérieur duquel une personne peut venir en contact, sur une partie importante de son corps, avec les parties conductrices environnantes et dont l'exiguïté limite les possibilités d'interrompre ce contact.

Overview
HD 60364-7-706:2007 is a critical European standard developed by CLC that addresses the safety requirements for low-voltage electrical installations in conducting locations with restricted movement. These locations primarily consist of metallic or conductive surroundings where a person’s movement is limited and prolonged contact with conductive parts is likely, increasing the risk of electric shock. This standard supplements general electrical installation rules by providing specific guidance to ensure protection against electrical hazards in such challenging environments.
The standard applies to both fixed electrical equipment installed within these conducting locations and portable equipment supplied for use there. It ensures harmonized safety practices across CENELEC member countries while allowing for some national variations.
Key Topics
HD 60364-7-706:2007 focuses on:
Scope and Definitions
- Clarifies what constitutes a conducting location with restricted movement.
- Delineates that it applies only where movement is physically constrained, excluding areas with free movement.
Protection Against Electric Shock
- Prohibits protective measures relying solely on obstacles or placing equipment out of reach.
- Prescribes specific protective measures for different equipment types:
- Hand-held tools and portable equipment: Must be supplied by SELV (Separated Extra-Low Voltage) or electrical separation with limitations on transformer windings.
- Handlamps: Supplied by SELV only.
- Fixed equipment: Several options including automatic disconnection with supplementary equipotential bonding, SELV or PELV systems with required equipotential bonding, electrical separation with restrictions, or Class II equipment with residual current device protection.
Equipotential Bonding and Earth Connections
- Requires bonding between all exposed conductive parts, extraneous conductive parts, and functional earth for equipment needing functional earth, ensuring consistent and safe potential across conductive elements.
Sources for SELV and PELV Systems
- Typically must be located outside the conducting location unless integrated as part of the fixed installation inside.
Additional National Conditions and Deviations
- Allows particular countries to maintain specific deviations, such as Ireland’s prohibition of electrical separation or Italy’s disallowance of PELV in these locations.
- Notices additional national variations in countries like France and Switzerland to accommodate local laws or practices.
Applications
This standard is essential for engineers, designers, and safety inspectors involved in electrical installations within:
- Industrial facilities with confined metallic enclosures or tanks where workers have limited mobility, such as cleaning or maintenance areas.
- Shipbuilding and maritime environments featuring spaces with metallic construction restricting movement.
- Specialized manufacturing plants with equipment rooms or metallic compartments that impede free movement.
- Welding and metal fabrication sites, provided exclusions noted for arc welding under other standards.
Compliance ensures:
- Enhanced protection from electric shock in hazardous working environments.
- Consistency with European regulatory requirements and harmonization across different member states.
- Safe operation of both fixed and portable electrical equipment under challenging conditions.
Related Standards
- IEC 60364 series - HD 60364-7-706 supplements these general low-voltage installation standards by addressing special locations.
- HD 407 and HD 427 - Cover installation and use of arc welding equipment, referenced for exclusions.
- HD 60364-7-704 - Addresses requirements for locations with a conductive part present but without restricted movement.
- Residual Current Device standards (Clause 415.1) - Critical for additional protection measures mandated in this standard.
- Class II Equipment standards (Clause 412) - Referenced for equipment insulation requirements in these environments.
By adhering to HD 60364-7-706:2007, stakeholders can ensure that low-voltage electrical systems in conducting locations with restricted movement are designed, installed, and maintained with optimal safety protocols tailored to these high-risk settings.
