Overview
HD 60364-4-42:2011/A1:2015 is the CENELEC harmonization document that adopts IEC 60364-4-42:2010 with Amendment 1 (2014). It covers protection for safety against thermal effects in low-voltage electrical installations, with a particular emphasis on risk reduction from electrical fires caused by arcing. This amendment introduces requirements and recommendations for arc fault detection devices (AFDDs) and updates normative references relevant to fire performance and protective devices.
Key Topics
- Scope: Protection against thermal effects (overheating and fire ignition) in low-voltage installations.
- Arc fault mitigation: Introduction of AFDDs as a recommended measure to reduce ignition risk from series and parallel arcing faults.
- Recommended locations for AFDDs:
- Premises with sleeping accommodation
- Locations with materials prone to fire (BE2)
- Buildings with combustible construction materials (CA2)
- Fire-propagating structures (CB2)
- Locations with irreplaceable goods
- Device placement: An AFDD should be installed at the origin of the final circuit it protects.
- AFDD types (per IEC 62606):
- AFDD as a separate AFD unit plus an opening device (used with a compatible overcurrent device)
- AFDD integrated with a protective device (e.g., circuit-breaker)
- AFDD unit declared to be assembled with a specified protective device on site
- Limitations: AFDDs complement but do not replace other protective measures (e.g., overcurrent protection, RCDs).
- Country notes: The amendment adds national notes such as USA requirements (NFPA 70 article 210.12) where arc-fault protection (AFCI) is mandated in specific living areas.
Applications
Who uses this standard and why:
- Electrical designers and specifiers - to select appropriate protective devices and layout final circuits to reduce fire risk.
- Installers and contractors - for correct placement and integration of AFDDs in residential, agricultural, and combustible-material environments.
- Building owners and facility managers - to apply proven measures that reduce the risk of fire and protect property and occupants.
- Product manufacturers and test laboratories - to design, test and certify AFDDs in compliance with IEC 62606 referenced by this amendment.
- Regulators and code committees - to incorporate AFDD recommendations into national standards and building codes.
