IEC 60364-7-713:2013

Overview

IEC 60364-7-713:2013 is an international standard established by the International Electrotechnical Commission (IEC) that specifically addresses the low-voltage electrical installations related to furniture and similar fitments. This standard sets out the particular requirements for wiring systems installed in furniture items such as desks, beds, cupboards, and shop display cases where electrical equipment like luminaires, socket-outlets, switching devices, and installation couplers are integrated.

The second edition, published in 2013, revises and expands upon the first edition from 1996. Key updates include extending the scope to cover electrical equipment connected to supplies with a nominal voltage up to 230 V and load currents not exceeding 32 A, including three-phase 32 A supplies. Additionally, it mandates enhanced protection measures such as residual current devices (RCDs) with rated residual operating currents not exceeding 30 mA.

Key Topics

• Scope and Application
  Applies to the electrical wiring of furniture connected to the building's electrical installation, ensuring safety and compliance where electrical equipment is embedded within furniture.

• Voltage and Current Limits
  Covers furniture connected to nominal voltages U₀ ≤ 230 V and total load currents ≤ 32 A, broadening the previous edition’s limits from single-phase 16 A only.

• Additional Protection Requirements
  Installation circuits in furniture must be protected using RCDs with residual operating currents not exceeding 30 mA, aligning with IEC 60364 part 4-41.

• Wiring and Cable Specifications

  • Rigid cables conforming to IEC 60227-3 or IEC 60245-1 for permanent connections or installation couplers (IEC 61535).
  • Flexible cables and cords to IEC 60245-4 or IEC 60227-5 for furniture intended to be movable.
  • Cables must be properly protected and securely fixed, including the use of ducts, conduits, or specially designed cable channels in furniture.

• Installation Accessories
  Flush-mounted and surface-mounted electrical boxes must meet the requirements of IEC 60670-1 and be designed to prevent electrical hazards from liquid spills.

• Harmonization with Other IEC Standards
  References to other IEC standards ensure integrated safety measures and proper selection of materials and equipment, such as installation couplers (IEC 61535), cable classification (IEC 62440), and special location requirements (IEC 60364-7-701).

Applications

IEC 60364-7-713:2013 is critically important for:

• Manufacturers of Electrically Equipped Furniture
  Ensuring their product designs comply with international safety and wiring standards to reduce risk of electric shock and fire.

• Electrical Installers and Contractors
  Guiding safe installation practices when integrating electrical systems into furniture, including desks, beds, cupboards, or retail display units.

• Facility Managers and Building Engineers
  Managing and inspecting furniture installations in commercial, residential, and institutional environments to ensure compliance and operational safety.

• Retail and Display Environments
  Where shop display cases and similar fixtures embed lighting and powered outlets for consumer products or lighting effects.

• Regulatory and Compliance Bodies
  Enforcing standard adherence in national electrical codes and regulations, facilitating consistent worldwide implementation.
